NAME
       perltidy - a perl script indenter and reformatter

SYNOPSIS
	   perltidy [ options ] file1 file2 file3 ...
		   (output goes to file1.tdy, file2.tdy, file3.tdy, ...)
	   perltidy [ options ] file1 -o outfile
	   perltidy [ options ] file1 -st >outfile
	   perltidy [ options ] <infile >outfile

DESCRIPTION
       Perltidy reads a perl script and writes an indented, reformatted script.

       Many users will find enough information in "EXAMPLES" to get started.  New users may
       benefit from the short tutorial which can be found at
       http://perltidy.sourceforge.net/tutorial.html

       A convenient aid to systematically defining a set of style parameters can be found at
       http://perltidy.sourceforge.net/stylekey.html

       Perltidy can produce output on either of two modes, depending on the existence of an -html
       flag.  Without this flag, the output is passed through a formatter.  The default
       formatting tries to follow the recommendations in perlstyle(1), but it can be controlled
       in detail with numerous input parameters, which are described in "FORMATTING OPTIONS".

       When the -html flag is given, the output is passed through an HTML formatter which is
       described in "HTML OPTIONS".

EXAMPLES
	 perltidy somefile.pl

       This will produce a file somefile.pl.tdy containing the script reformatted using the
       default options, which approximate the style suggested in perlstyle(1).	The source file
       somefile.pl is unchanged.

	 perltidy *.pl

       Execute perltidy on all .pl files in the current directory with the default options.  The
       output will be in files with an appended .tdy extension.  For any file with an error,
       there will be a file with extension .ERR.

	 perltidy -b file1.pl file2.pl

       Modify file1.pl and file2.pl in place, and backup the originals to file1.pl.bak and
       file2.pl.bak.  If file1.pl.bak and/or file2.pl.bak already exist, they will be
       overwritten.

	 perltidy -b -bext='/' file1.pl file2.pl

       Same as the previous example except that the backup files file1.pl.bak and file2.pl.bak
       will be deleted if there are no errors.

	 perltidy -gnu somefile.pl

       Execute perltidy on file somefile.pl with a style which approximates the GNU Coding
       Standards for C programs.  The output will be somefile.pl.tdy.

	 perltidy -i=3 somefile.pl

       Execute perltidy on file somefile.pl, with 3 columns for each level of indentation (-i=3)
       instead of the default 4 columns.  There will not be any tabs in the reformatted script,
       except for any which already exist in comments, pod documents, quotes, and here documents.
       Output will be somefile.pl.tdy.

	 perltidy -i=3 -et=8 somefile.pl

       Same as the previous example, except that leading whitespace will be entabbed with one tab
       character per 8 spaces.

	 perltidy -ce -l=72 somefile.pl

       Execute perltidy on file somefile.pl with all defaults except use "cuddled elses" (-ce)
       and a maximum line length of 72 columns (-l=72) instead of the default 80 columns.

	 perltidy -g somefile.pl

       Execute perltidy on file somefile.pl and save a log file somefile.pl.LOG which shows the
       nesting of braces, parentheses, and square brackets at the start of every line.

	 perltidy -html somefile.pl

       This will produce a file somefile.pl.html containing the script with html markup.  The
       output file will contain an embedded style sheet in the <HEAD> section which may be edited
       to change the appearance.

	 perltidy -html -css=mystyle.css somefile.pl

       This will produce a file somefile.pl.html containing the script with html markup.  This
       output file will contain a link to a separate style sheet file mystyle.css.  If the file
       mystyle.css does not exist, it will be created.	If it exists, it will not be overwritten.

	 perltidy -html -pre somefile.pl

       Write an html snippet with only the PRE section to somefile.pl.html.  This is useful when
       code snippets are being formatted for inclusion in a larger web page.  No style sheet will
       be written in this case.

	 perltidy -html -ss >mystyle.css

       Write a style sheet to mystyle.css and exit.

	 perltidy -html -frm mymodule.pm

       Write html with a frame holding a table of contents and the source code.  The output files
       will be mymodule.pm.html (the frame), mymodule.pm.toc.html (the table of contents), and
       mymodule.pm.src.html (the source code).

OPTIONS - OVERVIEW
       The entire command line is scanned for options, and they are processed before any files
       are processed.  As a result, it does not matter whether flags are before or after any
       filenames.  However, the relative order of parameters is important, with later parameters
       overriding the values of earlier parameters.

       For each parameter, there is a long name and a short name.  The short names are convenient
       for keyboard input, while the long names are self-documenting and therefore useful in
       scripts.  It is customary to use two leading dashes for long names, but one may be used.

       Most parameters which serve as on/off flags can be negated with a leading "n" (for the
       short name) or a leading "no" or "no-" (for the long name).  For example, the flag to
       outdent long quotes is is -olq or --outdent-long-quotes.  The flag to skip this is -nolq
       or --nooutdent-long-quotes or --no-outdent-long-quotes.

       Options may not be bundled together.  In other words, options -q and -g may NOT be entered
       as -qg.

       Option names may be terminated early as long as they are uniquely identified.  For
       example, instead of --dump-token-types, it would be sufficient to enter --dump-tok, or
       even --dump-t, to uniquely identify this command.

   I/O control
       The following parameters concern the files which are read and written.

       -h,    --help
	   Show summary of usage and exit.

       -o=filename,    --outfile=filename
	   Name of the output file (only if a single input file is being processed).  If no
	   output file is specified, and output is not redirected to the standard output, the
	   output will go to filename.tdy.

       -st,    --standard-output
	   Perltidy must be able to operate on an arbitrarily large number of files in a single
	   run, with each output being directed to a different output file.  Obviously this would
	   conflict with outputting to the single standard output device, so a special flag, -st,
	   is required to request outputting to the standard output.  For example,

	     perltidy somefile.pl -st >somefile.new.pl

	   This option may only be used if there is just a single input file.  The default is
	   -nst or --nostandard-output.

       -se,    --standard-error-output
	   If perltidy detects an error when processing file somefile.pl, its default behavior is
	   to write error messages to file somefile.pl.ERR.  Use -se to cause all error messages
	   to be sent to the standard error output stream instead.  This directive may be negated
	   with -nse.  Thus, you may place -se in a .perltidyrc and override it when desired with
	   -nse on the command line.

       -oext=ext,    --output-file-extension=ext
	   Change the extension of the output file to be ext instead of the default tdy (or html
	   in case the --html option is used).	See "Specifying File Extensions".

       -opath=path,    --output-path=path
	   When perltidy creates a filename for an output file, by default it merely appends an
	   extension to the path and basename of the input file.  This parameter causes the path
	   to be changed to path instead.

	   The path should end in a valid path separator character, but perltidy will try to add
	   one if it is missing.

	   For example

	    perltidy somefile.pl -opath=/tmp/

	   will produce /tmp/somefile.pl.tdy.  Otherwise, somefile.pl.tdy will appear in whatever
	   directory contains somefile.pl.

	   If the path contains spaces, it should be placed in quotes.

	   This parameter will be ignored if output is being directed to standard output, or if
	   it is being specified explicitly with the -o=s parameter.

       -b,    --backup-and-modify-in-place
	   Modify the input file or files in-place and save the original with the extension .bak.
	   Any existing .bak file will be deleted.  See next item for changing the default backup
	   extension, and for eliminating the backup file altogether.

	   A -b flag will be ignored if input is from standard input or goes to standard output,
	   or if the -html flag is set.

	   In particular, if you want to use both the -b flag and the -pbp
	   (--perl-best-practices) flag, then you must put a -nst flag after the -pbp flag
	   because it contains a -st flag as one of its components, which means that output will
	   go to the standard output stream.

       -bext=ext,    --backup-file-extension=ext
	   This parameter serves two purposes: (1) to change the extension of the backup file to
	   be something other than the default .bak, and (2) to indicate that no backup file
	   should be saved.

	   To change the default extension to something other than .bak see "Specifying File
	   Extensions".

	   A backup file of the source is always written, but you can request that it be deleted
	   at the end of processing if there were no errors.  This is risky unless the source
	   code is being maintained with a source code control system.

	   To indicate that the backup should be deleted include one forward slash, /, in the
	   extension.  If any text remains after the slash is removed it will be used to define
	   the backup file extension (which is always created and only deleted if there were no
	   errors).

	   Here are some examples:

	     Parameter		 Extension	    Backup File Treatment
	     <-bext=bak>	 F<.bak>	    Keep (same as the default behavior)
	     <-bext='/'>	 F<.bak>	    Delete if no errors
	     <-bext='/backup'>	 F<.backup>	    Delete if no errors
	     <-bext='original/'> F<.original>	    Delete if no errors

       -w,    --warning-output
	   Setting -w causes any non-critical warning messages to be reported as errors.  These
	   include messages about possible pod problems, possibly bad starting indentation level,
	   and cautions about indirect object usage.  The default, -nw or --nowarning-output, is
	   not to include these warnings.

       -q,    --quiet
	   Deactivate error messages and syntax checking (for running under an editor).

	   For example, if you use a vi-style editor, such as vim, you may execute perltidy as a
	   filter from within the editor using something like

	    :n1,n2!perltidy -q

	   where "n1,n2" represents the selected text.	Without the -q flag, any error message
	   may mess up your screen, so be prepared to use your "undo" key.

       -log,	--logfile
	   Save the .LOG file, which has many useful diagnostics.  Perltidy always creates a .LOG
	   file, but by default it is deleted unless a program bug is suspected.  Setting the
	   -log flag forces the log file to be saved.

       -g=n, --logfile-gap=n
	   Set maximum interval between input code lines in the logfile.  This purpose of this
	   flag is to assist in debugging nesting errors.  The value of "n" is optional.  If you
	   set the flag -g without the value of "n", it will be taken to be 1, meaning that every
	   line will be written to the log file.  This can be helpful if you are looking for a
	   brace, paren, or bracket nesting error.

	   Setting -g also causes the logfile to be saved, so it is not necessary to also include
	   -log.

	   If no -g flag is given, a value of 50 will be used, meaning that at least every 50th
	   line will be recorded in the logfile.  This helps prevent excessively long log files.

	   Setting a negative value of "n" is the same as not setting -g at all.

       -npro  --noprofile
	   Ignore any .perltidyrc command file.  Normally, perltidy looks first in your current
	   directory for a .perltidyrc file of parameters.  (The format is described below).  If
	   it finds one, it applies those options to the initial default values, and then it
	   applies any that have been defined on the command line.  If no .perltidyrc file is
	   found, it looks for one in your home directory.

	   If you set the -npro flag, perltidy will not look for this file.

       -pro=filename or  --profile=filename
	   To simplify testing and switching .perltidyrc files, this command may be used to
	   specify a configuration file which will override the default name of .perltidyrc.
	   There must not be a space on either side of the '=' sign.  For example, the line

	      perltidy -pro=testcfg

	   would cause file testcfg to be used instead of the default .perltidyrc.

	   A pathname begins with three dots, e.g. ".../.perltidyrc", indicates that the file
	   should be searched for starting in the current directory and working upwards. This
	   makes it easier to have multiple projects each with their own .perltidyrc in their
	   root directories.

       -opt,   --show-options
	   Write a list of all options used to the .LOG file.  Please see --dump-options for a
	   simpler way to do this.

       -f,   --force-read-binary
	   Force perltidy to process binary files.  To avoid producing excessive error messages,
	   perltidy skips files identified by the system as non-text.  However, valid perl
	   scripts containing binary data may sometimes be identified as non-text, and this flag
	   forces perltidy to process them.

FORMATTING OPTIONS
   Basic Options
       --notidy
	   This flag disables all formatting and causes the input to be copied unchanged to the
	   output except for possible changes in line ending characters and any pre- and post-
	   filters.  This can be useful in conjunction with a hierarchical set of .perltidyrc
	   files to avoid unwanted code tidying.  See also "Skipping Selected Sections of Code"
	   for a way to avoid tidying specific sections of code.

       -i=n,  --indent-columns=n
	   Use n columns per indentation level (default n=4).

       -l=n, --maximum-line-length=n
	   The default maximum line length is n=80 characters.	Perltidy will try to find line
	   break points to keep lines below this length. However, long quotes and side comments
	   may cause lines to exceed this length.  Setting -l=0 is equivalent to setting -l=(a
	   large number).

       -vmll, --variable-maximum-line-length
	   A problem arises using a fixed maximum line length with very deeply nested code and
	   data structures because eventually the amount of leading whitespace used for
	   indicating indation takes up most or all of the available line width, leaving little
	   or no space for the actual code or data.  One solution is to use a vary long line
	   length.  Another solution is to use the -vmll flag, which basically tells perltidy to
	   ignore leading whitespace when measuring the line length.

	   To be precise, when the -vmll parameter is set, the maximum line length of a line of
	   code will be M+L*I, where

		 M is the value of --maximum-line-length=M (-l=M), default 80,
		 I is the value of --indent-columns=I (-i=I), default 4,
		 L is the indentation level of the line of code

	   When this flag is set, the choice of breakpoints for a block of code should be
	   essentially independent of its nesting depth.  However, the absolute line lengths,
	   including leading whitespace, can still be arbitrarily large.  This problem can be
	   avoided by including the next parameter.

	   The default is not to do this (-nvmll).

       -wc=n, --whitespace-cycle=n
	   This flag also addresses problems with very deeply nested code and data structures.
	   When the nesting depth exceeds the value n the leading whitespace will be reduced and
	   start at a depth of 1 again.  The result is that blocks of code will shift back to the
	   left rather than moving arbitrarily far to the right.  This occurs cyclically to any
	   depth.

	   For example if one level of indentation equals 4 spaces (-i=4, the default), and one
	   uses -wc=15, then if the leading whitespace on a line exceeds about 4*15=60 spaces it
	   will be reduced back to 4*1=4 spaces and continue increasing from there.  If the
	   whitespace never exceeds this limit the formatting remains unchanged.

	   The combination of -vmll and -wc=n provides a solution to the problem of displaying
	   arbitrarily deep data structures and code in a finite window, although -wc=n may of
	   course be used without -vmll.

	   The default is not to use this, which can also be indicated using -wc=0.

       tabs
	   Using tab characters will almost certainly lead to future portability and maintenance
	   problems, so the default and recommendation is not to use them.  For those who prefer
	   tabs, however, there are two different options.

	   Except for possibly introducing tab indentation characters, as outlined below,
	   perltidy does not introduce any tab characters into your file, and it removes any tabs
	   from the code (unless requested not to do so with -fws).  If you have any tabs in your
	   comments, quotes, or here-documents, they will remain.

	   -et=n,   --entab-leading-whitespace
	       This flag causes each n initial space characters to be replaced by one tab
	       character.  Note that the integer n is completely independent of the integer
	       specified for indentation parameter, -i=n.

	   -t,	 --tabs
	       This flag causes one leading tab character to be inserted for each level of
	       indentation.  Certain other features are incompatible with this option, and if
	       these options are also given, then a warning message will be issued and this flag
	       will be unset.  One example is the -lp option.

	   -dt=n,   --default-tabsize=n
	       If the the first line of code passed to perltidy contains leading tabs but no tab
	       scheme is specified for the output stream then perltidy must guess how many spaces
	       correspond to each leading tab.	This number of spaces n corresponding to each
	       leading tab of the input stream may be specified with -dt=n.  The default is n=8.

	       This flag has no effect if a tab scheme is specified for the output stream,
	       because then the input stream is assumed to use the same tab scheme and
	       indentation spaces as for the output stream (any other assumption would lead to
	       unstable editing).

       -syn,   --check-syntax
	   This flag causes perltidy to run "perl -c -T" to check syntax of input and output.
	   (To change the flags passed to perl, see the next item, -pscf).  The results are
	   written to the .LOG file, which will be saved if an error is detected in the output
	   script.  The output script is not checked if the input script has a syntax error.
	   Perltidy does its own checking, but this option employs perl to get a "second
	   opinion".

	   If perl reports errors in the input file, they will not be reported in the error
	   output unless the --warning-output flag is given.

	   The default is NOT to do this type of syntax checking (although perltidy will still do
	   as much self-checking as possible).	The reason is that it causes all code in BEGIN
	   blocks to be executed, for all modules being used, and this opens the door to security
	   issues and infinite loops when running perltidy.

       -pscf=s, -perl-syntax-check-flags=s
	   When perl is invoked to check syntax, the normal flags are "-c -T".	In addition, if
	   the -x flag is given to perltidy, then perl will also be passed a -x flag.  It should
	   not normally be necessary to change these flags, but it can be done with the -pscf=s
	   flag.  For example, if the taint flag, "-T", is not wanted, the flag could be set to
	   be just -pscf=-c.

	   Perltidy will pass your string to perl with the exception that it will add a -c and -x
	   if appropriate.  The .LOG file will show exactly what flags were passed to perl.

       -io,   --indent-only
	   This flag is used to deactivate all formatting and line break changes within non-blank
	   lines of code.  When it is in effect, the only change to the script will be to the
	   indentation and blank lines.  And any flags controlling whitespace and newlines will
	   be ignored.	You might want to use this if you are perfectly happy with your
	   whitespace and line breaks, and merely want perltidy to handle the indentation.  (This
	   also speeds up perltidy by well over a factor of two, so it might be useful when
	   perltidy is merely being used to help find a brace error in a large script).

	   Setting this flag is equivalent to setting --freeze-newlines and --freeze-whitespace.

	   If you also want to keep your existing blank lines exactly as they are, you can add
	   --freeze-blank-lines.

       -ole=s,	--output-line-ending=s
	   where s="win", "dos", "unix", or "mac".  This flag tells perltidy to output line
	   endings for a specific system.  Normally, perltidy writes files with the line
	   separator character of the host system.  The "win" and "dos" flags have an identical
	   result.

       -ple,  --preserve-line-endings
	   This flag tells perltidy to write its output files with the same line endings as the
	   input file, if possible.  It should work for dos, unix, and mac line endings.  It will
	   only work if perltidy input comes from a filename (rather than stdin, for example).
	   If perltidy has trouble determining the input file line ending, it will revert to the
	   default behavior of using the line ending of the host system.

       -it=n,	--iterations=n
	   This flag causes perltidy to do n complete iterations.  The reason for this flag is
	   that code beautification is an iterative process and in some cases the output from
	   perltidy can be different if it is applied a second time.  For most purposes the
	   default of n=1 should be satisfactory.  However n=2 can be useful when a major style
	   change is being made, or when code is being beautified on check-in to a source code
	   control system.  It has been found to be extremely rare for the output to change after
	   2 iterations.  If a value n is greater than 2 is input then a convergence test will be
	   used to stop the iterations as soon as possible, almost always after 2 iterations.
	   See the next item for a simplified iteration control.

	   This flag has no effect when perltidy is used to generate html.

       -conv,	--converge
	   This flag is equivalent to -it=4 and is included to simplify iteration control.  For
	   all practical purposes one either does or does not want to be sure that the output is
	   converged, and there is no penalty to using a large iteration limit since perltidy
	   will check for convergence and stop iterating as soon as possible.  The default is
	   -nconv (no convergence check).  Using -conv will approximately double run time since
	   normally one extra iteration is required to verify convergence.

   Code Indentation Control
       -ci=n, --continuation-indentation=n
	   Continuation indentation is extra indentation spaces applied when a long line is
	   broken.  The default is n=2, illustrated here:

	    my $level =   # -ci=2
	      ( $max_index_to_go >= 0 ) ? $levels_to_go[0] : $last_output_level;

	   The same example, with n=0, is a little harder to read:

	    my $level =   # -ci=0
	    ( $max_index_to_go >= 0 ) ? $levels_to_go[0] : $last_output_level;

	   The value given to -ci is also used by some commands when a small space is required.
	   Examples are commands for outdenting labels, -ola, and control keywords, -okw.

	   When default values are not used, it is suggested that the value n given with -ci=n be
	   no more than about one-half of the number of spaces assigned to a full indentation
	   level on the -i=n command.

       -sil=n --starting-indentation-level=n
	   By default, perltidy examines the input file and tries to determine the starting
	   indentation level.  While it is often zero, it may not be zero for a code snippet
	   being sent from an editing session.

	   To guess the starting indentation level perltidy simply assumes that indentation
	   scheme used to create the code snippet is the same as is being used for the current
	   perltidy process.  This is the only sensible guess that can be made.  It should be
	   correct if this is true, but otherwise it probably won't.  For example, if the input
	   script was written with -i=2 and the current peltidy flags have -i=4, the wrong
	   initial indentation will be guessed for a code snippet which has non-zero initial
	   indentation. Likewise, if an entabbing scheme is used in the input script and not in
	   the current process then the guessed indentation will be wrong.

	   If the default method does not work correctly, or you want to change the starting
	   level, use -sil=n, to force the starting level to be n.

       List indentation using -lp, --line-up-parentheses
	   By default, perltidy indents lists with 4 spaces, or whatever value is specified with
	   -i=n.  Here is a small list formatted in this way:

	       # perltidy (default)
	       @month_of_year = (
		   'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
		   'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
	       );

	   Use the -lp flag to add extra indentation to cause the data to begin past the opening
	   parentheses of a sub call or list, or opening square bracket of an anonymous array, or
	   opening curly brace of an anonymous hash.  With this option, the above list would
	   become:

	       # perltidy -lp
	       @month_of_year = (
				  'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
				  'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
	       );

	   If the available line length (see -l=n ) does not permit this much space, perltidy
	   will use less.   For alternate placement of the closing paren, see the next section.

	   This option has no effect on code BLOCKS, such as if/then/else blocks, which always
	   use whatever is specified with -i=n.  Also, the existence of line breaks and/or block
	   comments between the opening and closing parens may cause perltidy to temporarily
	   revert to its default method.

	   Note: The -lp option may not be used together with the -t tabs option.  It may,
	   however, be used with the -et=n tab method.

	   In addition, any parameter which significantly restricts the ability of perltidy to
	   choose newlines will conflict with -lp and will cause -lp to be deactivated.  These
	   include -io, -fnl, -nanl, and -ndnl.  The reason is that the -lp indentation style can
	   require the careful coordination of an arbitrary number of break points in
	   hierarchical lists, and these flags may prevent that.

       -cti=n, --closing-token-indentation
	   The -cti=n flag controls the indentation of a line beginning with a ")", "]", or a
	   non-block "}".  Such a line receives:

	    -cti = 0 no extra indentation (default)
	    -cti = 1 extra indentation such that the closing token
		   aligns with its opening token.
	    -cti = 2 one extra indentation level if the line looks like:
		   );  or  ];  or  };
	    -cti = 3 one extra indentation level always

	   The flags -cti=1 and -cti=2 work well with the -lp flag (previous section).

	       # perltidy -lp -cti=1
	       @month_of_year = (
				  'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
				  'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
				);

	       # perltidy -lp -cti=2
	       @month_of_year = (
				  'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
				  'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
				  );

	   These flags are merely hints to the formatter and they may not always be followed.  In
	   particular, if -lp is not being used, the indentation for cti=1 is constrained to be
	   no more than one indentation level.

	   If desired, this control can be applied independently to each of the closing container
	   token types.  In fact, -cti=n is merely an abbreviation for -cpi=n -csbi=n -cbi=n,
	   where: -cpi or --closing-paren-indentation controls )'s, -csbi or
	   --closing-square-bracket-indentation controls ]'s, -cbi or --closing-brace-indentation
	   controls non-block }'s.

       -icp, --indent-closing-paren
	   The -icp flag is equivalent to -cti=2, described in the previous section.  The -nicp
	   flag is equivalent -cti=0.  They are included for backwards compatibility.

       -icb, --indent-closing-brace
	   The -icb option gives one extra level of indentation to a brace which terminates a
	   code block .  For example,

		   if ($task) {
		       yyy();
		       }    # -icb
		   else {
		       zzz();
		       }

	   The default is not to do this, indicated by -nicb.

       -olq, --outdent-long-quotes
	   When -olq is set, lines which is a quoted string longer than the value maximum-line-
	   length will have their indentation removed to make them more readable.  This is the
	   default.  To prevent such out-denting, use -nolq or --nooutdent-long-lines.

       -oll, --outdent-long-lines
	   This command is equivalent to --outdent-long-quotes and --outdent-long-comments, and
	   it is included for compatibility with previous versions of perltidy.  The negation of
	   this also works, -noll or --nooutdent-long-lines, and is equivalent to setting -nolq
	   and -nolc.

       Outdenting Labels: -ola,  --outdent-labels
	   This command will cause labels to be outdented by 2 spaces (or whatever -ci has been
	   set to), if possible.  This is the default.	For example:

		   my $i;
		 LOOP: while ( $i = <FOTOS> ) {
		       chomp($i);
		       next unless $i;
		       fixit($i);
		   }

	   Use -nola to not outdent labels.

       Outdenting Keywords
	   -okw,  --outdent-keywords
	       The command -okw will will cause certain leading control keywords to be outdented
	       by 2 spaces (or whatever -ci has been set to), if possible.  By default, these
	       keywords are "redo", "next", "last", "goto", and "return".  The intention is to
	       make these control keywords easier to see.  To change this list of keywords being
	       outdented, see the next section.

	       For example, using "perltidy -okw" on the previous example gives:

		       my $i;
		     LOOP: while ( $i = <FOTOS> ) {
			   chomp($i);
			 next unless $i;
			   fixit($i);
		       }

	       The default is not to do this.

	   Specifying Outdented Keywords: -okwl=string,  --outdent-keyword-list=string
	       This command can be used to change the keywords which are outdented with the -okw
	       command.  The parameter string is a required list of perl keywords, which should
	       be placed in quotes if there are more than one.	By itself, it does not cause any
	       outdenting to occur, so the -okw command is still required.

	       For example, the commands "-okwl="next last redo goto" -okw" will cause those four
	       keywords to be outdented.  It is probably simplest to place any -okwl command in a
	       .perltidyrc file.

   Whitespace Control
       Whitespace refers to the blank space between variables, operators, and other code tokens.

       -fws,  --freeze-whitespace
	   This flag causes your original whitespace to remain unchanged, and causes the rest of
	   the whitespace commands in this section, the Code Indentation section, and the Comment
	   Control section to be ignored.

       Tightness of curly braces, parentheses, and square brackets.
	   Here the term "tightness" will mean the closeness with which pairs of enclosing
	   tokens, such as parentheses, contain the quantities within.	A numerical value of 0,
	   1, or 2 defines the tightness, with 0 being least tight and 2 being most tight.
	   Spaces within containers are always symmetric, so if there is a space after a "(" then
	   there will be a space before the corresponding ")".

	   The -pt=n or --paren-tightness=n parameter controls the space within parens.  The
	   example below shows the effect of the three possible values, 0, 1, and 2:

	    if ( ( my $len_tab = length( $tabstr ) ) > 0 ) {  # -pt=0
	    if ( ( my $len_tab = length($tabstr) ) > 0 ) {    # -pt=1 (default)
	    if ((my $len_tab = length($tabstr)) > 0) {	      # -pt=2

	   When n is 0, there is always a space to the right of a '(' and to the left of a ')'.
	   For n=2 there is never a space.  For n=1, the default, there is a space unless the
	   quantity within the parens is a single token, such as an identifier or quoted string.

	   Likewise, the parameter -sbt=n or --square-bracket-tightness=n controls the space
	   within square brackets, as illustrated below.

	    $width = $col[ $j + $k ] - $col[ $j ];  # -sbt=0
	    $width = $col[ $j + $k ] - $col[$j];    # -sbt=1 (default)
	    $width = $col[$j + $k] - $col[$j];	    # -sbt=2

	   Curly braces which do not contain code blocks are controlled by the parameter -bt=n or
	   --brace-tightness=n.

	    $obj->{ $parsed_sql->{ 'table' }[0] };    # -bt=0
	    $obj->{ $parsed_sql->{'table'}[0] };      # -bt=1 (default)
	    $obj->{$parsed_sql->{'table'}[0]};	      # -bt=2

	   And finally, curly braces which contain blocks of code are controlled by the parameter
	   -bbt=n or --block-brace-tightness=n as illustrated in the example below.

	    %bf = map { $_ => -M $_ } grep { /\.deb$/ } dirents '.'; # -bbt=0 (default)
	    %bf = map { $_ => -M $_ } grep {/\.deb$/} dirents '.';   # -bbt=1
	    %bf = map {$_ => -M $_} grep {/\.deb$/} dirents '.';     # -bbt=2

	   To simplify input in the case that all of the tightness flags have the same value <n>,
	   the parameter <-act=n> or --all-containers-tightness=n is an abbreviation for the
	   combination <-pt=n -sbt=n -bt=n -bbt=n>.

       -tso,   --tight-secret-operators
	   The flag -tso causes certain perl token sequences (secret operators) which might be
	   considered to be a single operator to be formatted "tightly" (without spaces).  The
	   operators currently modified by this flag are:

		0+  +0	()x!! ~~<>  ,=>   =( )=

	   For example the sequence 0 +,  which converts a string to a number, would be formatted
	   without a space: 0+ when the -tso flag is set.  This flag is off by default.

       -sts,   --space-terminal-semicolon
	   Some programmers prefer a space before all terminal semicolons.  The default is for no
	   such space, and is indicated with -nsts or --nospace-terminal-semicolon.

		   $i = 1 ;	#  -sts
		   $i = 1;	#  -nsts   (default)

       -sfs,   --space-for-semicolon
	   Semicolons within for loops may sometimes be hard to see, particularly when commas are
	   also present.  This option places spaces on both sides of these special semicolons,
	   and is the default.	Use -nsfs or --nospace-for-semicolon to deactivate it.

	    for ( @a = @$ap, $u = shift @a ; @a ; $u = $v ) {  # -sfs (default)
	    for ( @a = @$ap, $u = shift @a; @a; $u = $v ) {    # -nsfs

       -asc,  --add-semicolons
	   Setting -asc allows perltidy to add any missing optional semicolon at the end of a
	   line which is followed by a closing curly brace on the next line.  This is the
	   default, and may be deactivated with -nasc or --noadd-semicolons.

       -dsm,  --delete-semicolons
	   Setting -dsm allows perltidy to delete extra semicolons which are simply empty
	   statements.	This is the default, and may be deactivated with -ndsm or
	   --nodelete-semicolons.  (Such semicolons are not deleted, however, if they would
	   promote a side comment to a block comment).

       -aws,  --add-whitespace
	   Setting this option allows perltidy to add certain whitespace improve code
	   readability.  This is the default. If you do not want any whitespace added, but are
	   willing to have some whitespace deleted, use -naws.	(Use -fws to leave whitespace
	   completely unchanged).

       -dws,  --delete-old-whitespace
	   Setting this option allows perltidy to remove some old whitespace between characters,
	   if necessary.  This is the default.	If you do not want any old whitespace removed,
	   use -ndws or --nodelete-old-whitespace.

       Detailed whitespace controls around tokens
	   For those who want more detailed control over the whitespace around tokens, there are
	   four parameters which can directly modify the default whitespace rules built into
	   perltidy for any token.  They are:

	   -wls=s or --want-left-space=s,

	   -nwls=s or --nowant-left-space=s,

	   -wrs=s or --want-right-space=s,

	   -nwrs=s or --nowant-right-space=s.

	   These parameters are each followed by a quoted string, s, containing a list of token
	   types.  No more than one of each of these parameters should be specified, because
	   repeating a command-line parameter always overwrites the previous one before perltidy
	   ever sees it.

	   To illustrate how these are used, suppose it is desired that there be no space on
	   either side of the token types = + - / *.  The following two parameters would specify
	   this desire:

	     -nwls="= + - / *"	  -nwrs="= + - / *"

	   (Note that the token types are in quotes, and that they are separated by spaces).
	   With these modified whitespace rules, the following line of math:

	     $root = -$b + sqrt( $b * $b - 4. * $a * $c ) / ( 2. * $a );

	   becomes this:

	     $root=-$b+sqrt( $b*$b-4.*$a*$c )/( 2.*$a );

	   These parameters should be considered to be hints to perltidy rather than fixed rules,
	   because perltidy must try to resolve conflicts that arise between them and all of the
	   other rules that it uses.  One conflict that can arise is if, between two tokens, the
	   left token wants a space and the right one doesn't.	In this case, the token not
	   wanting a space takes priority.

	   It is necessary to have a list of all token types in order to create this type of
	   input.  Such a list can be obtained by the command --dump-token-types.  Also try the
	   -D flag on a short snippet of code and look at the .DEBUG file to see the
	   tokenization.

	   WARNING Be sure to put these tokens in quotes to avoid having them misinterpreted by
	   your command shell.

       Space between specific keywords and opening paren
	   When an opening paren follows a Perl keyword, no space is introduced after the
	   keyword, unless it is (by default) one of these:

	      my local our and or eq ne if else elsif until unless
	      while for foreach return switch case given when

	   These defaults can be modified with two commands:

	   -sak=s  or --space-after-keyword=s  adds keywords.

	   -nsak=s  or --nospace-after-keyword=s  removes keywords.

	   where s is a list of keywords (in quotes if necessary).  For example,

	     my ( $a, $b, $c ) = @_;	# default
	     my( $a, $b, $c ) = @_;	# -nsak="my local our"

	   The abbreviation -nsak='*' is equivalent to including all of the keywords in the above
	   list.

	   When both -nsak=s and -sak=s commands are included, the -nsak=s command is executed
	   first.  For example, to have space after only the keywords (my, local, our) you could
	   use -nsak="*" -sak="my local our".

	   To put a space after all keywords, see the next item.

       Space between all keywords and opening parens
	   When an opening paren follows a function or keyword, no space is introduced after the
	   keyword except for the keywords noted in the previous item.	To always put a space
	   between a function or keyword and its opening paren, use the command:

	   -skp  or --space-keyword-paren

	   You will probably also want to use the flag -sfp (next item) too.

       Space between all function names and opening parens
	   When an opening paren follows a function the default is not to introduce a space.  To
	   cause a space to be introduced use:

	   -sfp  or --space-function-paren

	     myfunc( $a, $b, $c );    # default
	     myfunc ( $a, $b, $c );   # -sfp

	   You will probably also want to use the flag -skp (previous item) too.

       Trimming whitespace around "qw" quotes
	   -tqw or --trim-qw provide the default behavior of trimming spaces around multi-line
	   "qw" quotes and indenting them appropriately.

	   -ntqw or --notrim-qw cause leading and trailing whitespace around multi-line "qw"
	   quotes to be left unchanged.  This option will not normally be necessary, but was
	   added for testing purposes, because in some versions of perl, trimming "qw" quotes
	   changes the syntax tree.

   Comment Controls
       Perltidy has a number of ways to control the appearance of both block comments and side
       comments.  The term block comment here refers to a full-line comment, whereas side comment
       will refer to a comment which appears on a line to the right of some code.

       -ibc,  --indent-block-comments
	   Block comments normally look best when they are indented to the same level as the code
	   which follows them.	This is the default behavior, but you may use -nibc to keep block
	   comments left-justified.  Here is an example:

			# this comment is indented	(-ibc, default)
			if ($task) { yyy(); }

	   The alternative is -nibc:

	    # this comment is not indented		(-nibc)
			if ($task) { yyy(); }

	   See also the next item, -isbc, as well as -sbc, for other ways to have some indented
	   and some outdented block comments.

       -isbc,  --indent-spaced-block-comments
	   If there is no leading space on the line, then the comment will not be indented, and
	   otherwise it may be.

	   If both -ibc and -isbc are set, then -isbc takes priority.

       -olc, --outdent-long-comments
	   When -olc is set, lines which are full-line (block) comments longer than the value
	   maximum-line-length will have their indentation removed.  This is the default; use
	   -nolc to prevent outdenting.

       -msc=n,	--minimum-space-to-comment=n
	   Side comments look best when lined up several spaces to the right of code.  Perltidy
	   will try to keep comments at least n spaces to the right.  The default is n=4 spaces.

       -fpsc=n,  --fixed-position-side-comment=n
	   This parameter tells perltidy to line up side comments in column number n whenever
	   possible.  The default, n=0, is not do do this.

       -iscl,  --ignore-side-comment-lengths
	   This parameter causes perltidy to ignore the length of side comments when setting line
	   breaks.  The default, -niscl, is to include the length of side comments when breaking
	   lines to stay within the length prescribed by the -l=n maximum line length parameter.
	   For example, the following long single line would remain intact with -l=80 and -iscl:

		perltidy -l=80 -iscl
		   $vmsfile =~ s/;[\d\-]*$//; # Clip off version number; we can use a newer version as well

	   whereas without the -iscl flag the line will be broken:

		perltidy -l=80
		   $vmsfile =~ s/;[\d\-]*$//
		     ;	  # Clip off version number; we can use a newer version as well

       -hsc, --hanging-side-comments
	   By default, perltidy tries to identify and align "hanging side comments", which are
	   something like this:

		   my $IGNORE = 0;    # This is a side comment
				      # This is a hanging side comment
				      # And so is this

	   A comment is considered to be a hanging side comment if (1) it immediately follows a
	   line with a side comment, or another hanging side comment, and (2) there is some
	   leading whitespace on the line.  To deactivate this feature, use -nhsc or
	   --nohanging-side-comments.  If block comments are preceded by a blank line, or have no
	   leading whitespace, they will not be mistaken as hanging side comments.

       Closing Side Comments
	   A closing side comment is a special comment which perltidy can automatically create
	   and place after the closing brace of a code block.  They can be useful for code
	   maintenance and debugging.  The command -csc (or --closing-side-comments) adds or
	   updates closing side comments.  For example, here is a small code snippet

		   sub message {
		       if ( !defined( $_[0] ) ) {
			   print("Hello, World\n");
		       }
		       else {
			   print( $_[0], "\n" );
		       }
		   }

	   And here is the result of processing with "perltidy -csc":

		   sub message {
		       if ( !defined( $_[0] ) ) {
			   print("Hello, World\n");
		       }
		       else {
			   print( $_[0], "\n" );
		       }
		   } ## end sub message

	   A closing side comment was added for "sub message" in this case, but not for the "if"
	   and "else" blocks, because they were below the 6 line cutoff limit for adding closing
	   side comments.  This limit may be changed with the -csci command, described below.

	   The command -dcsc (or --delete-closing-side-comments) reverses this process and
	   removes these comments.

	   Several commands are available to modify the behavior of these two basic commands,
	   -csc and -dcsc:

	   -csci=n, or --closing-side-comment-interval=n
	       where "n" is the minimum number of lines that a block must have in order for a
	       closing side comment to be added.  The default value is "n=6".  To illustrate:

		       # perltidy -csci=2 -csc
		       sub message {
			   if ( !defined( $_[0] ) ) {
			       print("Hello, World\n");
			   } ## end if ( !defined( $_[0] ))
			   else {
			       print( $_[0], "\n" );
			   } ## end else [ if ( !defined( $_[0] ))
		       } ## end sub message

	       Now the "if" and "else" blocks are commented.  However, now this has become very
	       cluttered.

	   -cscp=string, or --closing-side-comment-prefix=string
	       where string is the prefix used before the name of the block type.  The default
	       prefix, shown above, is "## end".  This string will be added to closing side
	       comments, and it will also be used to recognize them in order to update, delete,
	       and format them.  Any comment identified as a closing side comment will be placed
	       just a single space to the right of its closing brace.

	   -cscl=string, or --closing-side-comment-list-string
	       where "string" is a list of block types to be tagged with closing side comments.
	       By default, all code block types preceded by a keyword or label (such as "if",
	       "sub", and so on) will be tagged.  The -cscl command changes the default list to
	       be any selected block types; see "Specifying Block Types".  For example, the
	       following command requests that only "sub"'s, labels, "BEGIN", and "END" blocks be
	       affected by any -csc or -dcsc operation:

		  -cscl="sub : BEGIN END"

	   -csct=n, or --closing-side-comment-maximum-text=n
	       The text appended to certain block types, such as an "if" block, is whatever lies
	       between the keyword introducing the block, such as "if", and the opening brace.
	       Since this might be too much text for a side comment, there needs to be a limit,
	       and that is the purpose of this parameter.  The default value is "n=20", meaning
	       that no additional tokens will be appended to this text after its length reaches
	       20 characters.  Omitted text is indicated with "...".  (Tokens, including sub
	       names, are never truncated, however, so actual lengths may exceed this).  To
	       illustrate, in the above example, the appended text of the first block is " (
	       !defined( $_[0] )...".  The existing limit of "n=20" caused this text to be
	       truncated, as indicated by the "...".  See the next flag for additional control of
	       the abbreviated text.

	   -cscb, or --closing-side-comments-balanced
	       As discussed in the previous item, when the closing-side-comment-maximum-text
	       limit is exceeded the comment text must be truncated.  Older versions of perltidy
	       terminated with three dots, and this can still be achieved with -ncscb:

		 perltidy -csc -ncscb
		 } ## end foreach my $foo (sort { $b cmp $a ...

	       However this causes a problem with editors editors which cannot recognize comments
	       or are not configured to do so because they cannot "bounce" around in the text
	       correctly.  The -cscb flag has been added to help them by appending appropriate
	       balancing structure:

		 perltidy -csc -cscb
		 } ## end foreach my $foo (sort { $b cmp $a ... })

	       The default is -cscb.

	   -csce=n, or --closing-side-comment-else-flag=n
	       The default, n=0, places the text of the opening "if" statement after any terminal
	       "else".

	       If n=2 is used, then each "elsif" is also given the text of the opening "if"
	       statement.  Also, an "else" will include the text of a preceding "elsif"
	       statement.  Note that this may result some long closing side comments.

	       If n=1 is used, the results will be the same as n=2 whenever the resulting line
	       length is less than the maximum allowed.  =item -cscb, or
	       --closing-side-comments-balanced

	       When using closing-side-comments, and the closing-side-comment-maximum-text limit
	       is exceeded, then the comment text must be abbreviated.	It is terminated with
	       three dots if the -cscb flag is negated:

		 perltidy -csc -ncscb
		 } ## end foreach my $foo (sort { $b cmp $a ...

	       This causes a problem with older editors which do not recognize comments because
	       they cannot "bounce" around in the text correctly.  The -cscb flag tries to help
	       them by appending appropriate terminal balancing structures:

		 perltidy -csc -cscb
		 } ## end foreach my $foo (sort { $b cmp $a ... })

	       The default is -cscb.

	   -cscw, or --closing-side-comment-warnings
	       This parameter is intended to help make the initial transition to the use of
	       closing side comments.  It causes two things to happen if a closing side comment
	       replaces an existing, different closing side comment:  first, an error message
	       will be issued, and second, the original side comment will be placed alone on a
	       new specially marked comment line for later attention.

	       The intent is to avoid clobbering existing hand-written side comments which happen
	       to match the pattern of closing side comments. This flag should only be needed on
	       the first run with -csc.

	   Important Notes on Closing Side Comments:

	   o   Closing side comments are only placed on lines terminated with a closing brace.
	       Certain closing styles, such as the use of cuddled elses (-ce), preclude the
	       generation of some closing side comments.

	   o   Please note that adding or deleting of closing side comments takes place only
	       through the commands -csc or -dcsc.  The other commands, if used, merely modify
	       the behavior of these two commands.

	   o   It is recommended that the -cscw flag be used along with -csc on the first use of
	       perltidy on a given file.  This will prevent loss of any existing side comment
	       data which happens to have the csc prefix.

	   o   Once you use -csc, you should continue to use it so that any closing side comments
	       remain correct as code changes.	Otherwise, these comments will become incorrect
	       as the code is updated.

	   o   If you edit the closing side comments generated by perltidy, you must also change
	       the prefix to be different from the closing side comment prefix.  Otherwise, your
	       edits will be lost when you rerun perltidy with -csc.   For example, you could
	       simply change "## end" to be "## End", since the test is case sensitive.  You may
	       also want to use the -ssc flag to keep these modified closing side comments spaced
	       the same as actual closing side comments.

	   o   Temporarily generating closing side comments is a useful technique for exploring
	       and/or debugging a perl script, especially one written by someone else.	You can
	       always remove them with -dcsc.

       Static Block Comments
	   Static block comments are block comments with a special leading pattern, "##" by
	   default, which will be treated slightly differently from other block comments.  They
	   effectively behave as if they had glue along their left and top edges, because they
	   stick to the left edge and previous line when there is no blank spaces in those
	   places.  This option is particularly useful for controlling how commented code is
	   displayed.

	   -sbc, --static-block-comments
	       When -sbc is used, a block comment with a special leading pattern, "##" by
	       default, will be treated specially.

	       Comments so identified  are treated as follows:

	       o   If there is no leading space on the line, then the comment will not be
		   indented, and otherwise it may be,

	       o   no new blank line will be inserted before such a comment, and

	       o   such a comment will never become a hanging side comment.

	       For example, assuming @month_of_year is left-adjusted:

		   @month_of_year = (	 # -sbc (default)
		       'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct',
		   ##  'Dec', 'Nov'
		       'Nov', 'Dec');

	       Without this convention, the above code would become

		   @month_of_year = (	# -nsbc
		       'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct',

		       ##  'Dec', 'Nov'
		       'Nov', 'Dec'
		   );

	       which is not as clear.  The default is to use -sbc.  This may be deactivated with
	       -nsbc.

	   -sbcp=string, --static-block-comment-prefix=string
	       This parameter defines the prefix used to identify static block comments when the
	       -sbc parameter is set.  The default prefix is "##", corresponding to "-sbcp=##".
	       The prefix is actually part of a perl pattern used to match lines and it must
	       either begin with "#" or "^#".  In the first case a prefix ^\s* will be added to
	       match any leading whitespace, while in the second case the pattern will match only
	       comments with no leading whitespace.  For example, to identify all comments as
	       static block comments, one would use "-sbcp=#".	To identify all left-adjusted
	       comments as static block comments, use "-sbcp='^#'".

	       Please note that -sbcp merely defines the pattern used to identify static block
	       comments; it will not be used unless the switch -sbc is set.  Also, please be
	       aware that since this string is used in a perl regular expression which identifies
	       these comments, it must enable a valid regular expression to be formed.

	       A pattern which can be useful is:

		   -sbcp=^#{2,}[^\s#]

	       This pattern requires a static block comment to have at least one character which
	       is neither a # nor a space.  It allows a line containing only '#' characters to be
	       rejected as a static block comment.  Such lines are often used at the start and
	       end of header information in subroutines and should not be separated from the
	       intervening comments, which typically begin with just a single '#'.

	   -osbc, --outdent-static-block-comments
	       The command -osbc will will cause static block comments to be outdented by 2
	       spaces (or whatever -ci=n has been set to), if possible.

       Static Side Comments
	   Static side comments are side comments with a special leading pattern.  This option
	   can be useful for controlling how commented code is displayed when it is a side
	   comment.

	   -ssc, --static-side-comments
	       When -ssc is used, a side comment with a static leading pattern, which is "##" by
	       default, will be be spaced only a single space from previous character, and it
	       will not be vertically aligned with other side comments.

	       The default is -nssc.

	   -sscp=string, --static-side-comment-prefix=string
	       This parameter defines the prefix used to identify static side comments when the
	       -ssc parameter is set.  The default prefix is "##", corresponding to "-sscp=##".

	       Please note that -sscp merely defines the pattern used to identify static side
	       comments; it will not be used unless the switch -ssc is set.  Also, note that this
	       string is used in a perl regular expression which identifies these comments, so it
	       must enable a valid regular expression to be formed.

   Skipping Selected Sections of Code
       Selected lines of code may be passed verbatim to the output without any formatting.  This
       feature is enabled by default but can be disabled with the --noformat-skipping or -nfs
       flag.  It should be used sparingly to avoid littering code with markers, but it might be
       helpful for working around occasional problems.	For example it might be useful for
       keeping the indentation of old commented code unchanged, keeping indentation of long
       blocks of aligned comments unchanged, keeping certain list formatting unchanged, or
       working around a glitch in perltidy.

       -fs,  --format-skipping
	   This flag, which is enabled by default, causes any code between special beginning and
	   ending comment markers to be passed to the output without formatting.  The default
	   beginning marker is #<<< and the default ending marker is #>>> but they may be changed
	   (see next items below).  Additional text may appear on these special comment lines
	   provided that it is separated from the marker by at least one space.  For example

	    #<<<  do not let perltidy touch this
	       my @list = (1,
			   1, 1,
			   1, 2, 1,
			   1, 3, 3, 1,
			   1, 4, 6, 4, 1,);
	    #>>>

	   The comment markers may be placed at any location that a block comment may appear.  If
	   they do not appear to be working, use the -log flag and examine the .LOG file.  Use
	   -nfs to disable this feature.

       -fsb=string,  --format-skipping-begin=string
	   The -fsb=string parameter may be used to change the beginning marker for format
	   skipping.  The default is equivalent to -fsb='#<<<'.  The string that you enter must
	   begin with a # and should be in quotes as necessary to get past the command shell of
	   your system.  It is actually the leading text of a pattern that is constructed by
	   appending a '\s', so you must also include backslashes for characters to be taken
	   literally rather than as patterns.

	   Some examples show how example strings become patterns:

	    -fsb='#\{\{\{' becomes /^#\{\{\{\s/  which matches	#{{{ but not #{{{{
	    -fsb='#\*\*'   becomes /^#\*\*\s/	 which matches	#** but not #***
	    -fsb='#\*{2,}' becomes /^#\*{2,}\s/  which matches	#** and #*****

       -fse=string,  --format-skipping-end=string
	   The -fsb=string is the corresponding parameter used to change the ending marker for
	   format skipping.  The default is equivalent to -fse='#<<<'.

   Line Break Control
       The parameters in this section control breaks after non-blank lines of code.  Blank lines
       are controlled separately by parameters in the section "Blank Line Control".

       -fnl,  --freeze-newlines
	   If you do not want any changes to the line breaks within lines of code in your script,
	   set -fnl, and they will remain fixed, and the rest of the commands in this section and
	   sections "Controlling List Formatting", "Retaining or Ignoring Existing Line Breaks".
	   You may want to use -noll with this.

	   Note: If you also want to keep your blank lines exactly as they are, you can use the
	   -fbl flag which is described in the section "Blank Line Control".

       -ce,   --cuddled-else
	   Enable the "cuddled else" style, in which "else" and "elsif" are follow immediately
	   after the curly brace closing the previous block.  The default is not to use cuddled
	   elses, and is indicated with the flag -nce or --nocuddled-else.  Here is a comparison
	   of the alternatives:

	     if ($task) {
		 yyy();
	     } else {	 # -ce
		 zzz();
	     }

	     if ($task) {
		   yyy();
	     }
	     else {    # -nce  (default)
		   zzz();
	     }

       -bl,    --opening-brace-on-new-line
	   Use the flag -bl to place the opening brace on a new line:

	     if ( $input_file eq '-' )	  # -bl
	     {
		 important_function();
	     }

	   This flag applies to all structural blocks, including named sub's (unless the -sbl
	   flag is set -- see next item).

	   The default style, -nbl, places an opening brace on the same line as the keyword
	   introducing it.  For example,

	     if ( $input_file eq '-' ) {   # -nbl (default)

       -sbl,	--opening-sub-brace-on-new-line
	   The flag -sbl can be used to override the value of -bl for the opening braces of named
	   sub's.  For example,

	    perltidy -sbl

	   produces this result:

	    sub message
	    {
	       if (!defined($_[0])) {
		   print("Hello, World\n");
	       }
	       else {
		   print($_[0], "\n");
	       }
	    }

	   This flag is negated with -nsbl.  If -sbl is not specified, the value of -bl is used.

       -asbl,	 --opening-anonymous-sub-brace-on-new-line
	   The flag -asbl is like the -sbl flag except that it applies to anonymous sub's instead
	   of named subs. For example

	    perltidy -asbl

	   produces this result:

	    $a = sub
	    {
		if ( !defined( $_[0] ) ) {
		    print("Hello, World\n");
		}
		else {
		    print( $_[0], "\n" );
		}
	    };

	   This flag is negated with -nasbl, and the default is -nasbl.

       -bli,	--brace-left-and-indent
	   The flag -bli is the same as -bl but in addition it causes one unit of continuation
	   indentation ( see -ci ) to be placed before an opening and closing block braces.

	   For example,

		   if ( $input_file eq '-' )	# -bli
		     {
		       important_function();
		     }

	   By default, this extra indentation occurs for blocks of type: if, elsif, else, unless,
	   for, foreach, sub, while, until, and also with a preceding label.  The next item shows
	   how to change this.

       -blil=s,    --brace-left-and-indent-list=s
	   Use this parameter to change the types of block braces for which the -bli flag
	   applies; see "Specifying Block Types".  For example, -blil='if elsif else' would apply
	   it to only "if/elsif/else" blocks.

       -bar,	--opening-brace-always-on-right
	   The default style, -nbl places the opening code block brace on a new line if it does
	   not fit on the same line as the opening keyword, like this:

		   if ( $bigwasteofspace1 && $bigwasteofspace2
		     || $bigwasteofspace3 && $bigwasteofspace4 )
		   {
		       big_waste_of_time();
		   }

	   To force the opening brace to always be on the right, use the -bar flag.  In this
	   case, the above example becomes

		   if ( $bigwasteofspace1 && $bigwasteofspace2
		     || $bigwasteofspace3 && $bigwasteofspace4 ) {
		       big_waste_of_time();
		   }

	   A conflict occurs if both -bl and -bar are specified.

       -otr,  --opening-token-right and related flags
	   The -otr flag is a hint that perltidy should not place a break between a comma and an
	   opening token.  For example:

	       # default formatting
	       push @{ $self->{$module}{$key} },
		 {
		   accno       => $ref->{accno},
		   description => $ref->{description}
		 };

	       # perltidy -otr
	       push @{ $self->{$module}{$key} }, {
		   accno       => $ref->{accno},
		   description => $ref->{description}
		 };

	   The flag -otr is actually an abbreviation for three other flags which can be used to
	   control parens, hash braces, and square brackets separately if desired:

	     -opr  or --opening-paren-right
	     -ohbr or --opening-hash-brace-right
	     -osbr or --opening-square-bracket-right

       Vertical tightness of non-block curly braces, parentheses, and square brackets.
	   These parameters control what shall be called vertical tightness.  Here are the main
	   points:

	   o   Opening tokens (except for block braces) are controlled by -vt=n, or
	       --vertical-tightness=n, where

		-vt=0 always break a line after opening token (default).
		-vt=1 do not break unless this would produce more than one
			step in indentation in a line.
		-vt=2 never break a line after opening token

	   o   You must also use the -lp flag when you use the -vt flag; the reason is explained
	       below.

	   o   Closing tokens (except for block braces) are controlled by -vtc=n, or
	       --vertical-tightness-closing=n, where

		-vtc=0 always break a line before a closing token (default),
		-vtc=1 do not break before a closing token which is followed
		       by a semicolon or another closing token, and is not in
		       a list environment.
		-vtc=2 never break before a closing token.

	       The rules for -vtc=1 are designed to maintain a reasonable balance between
	       tightness and readability in complex lists.

	   o   Different controls may be applied to to different token types, and it is also
	       possible to control block braces; see below.

	   o   Finally, please note that these vertical tightness flags are merely hints to the
	       formatter, and it cannot always follow them.  Things which make it difficult or
	       impossible include comments, blank lines, blocks of code within a list, and
	       possibly the lack of the -lp parameter.	Also, these flags may be ignored for very
	       small lists (2 or 3 lines in length).

	   Here are some examples:

	       # perltidy -lp -vt=0 -vtc=0
	       %romanNumerals = (
				  one	=> 'I',
				  two	=> 'II',
				  three => 'III',
				  four	=> 'IV',
	       );

	       # perltidy -lp -vt=1 -vtc=0
	       %romanNumerals = ( one	=> 'I',
				  two	=> 'II',
				  three => 'III',
				  four	=> 'IV',
	       );

	       # perltidy -lp -vt=1 -vtc=1
	       %romanNumerals = ( one	=> 'I',
				  two	=> 'II',
				  three => 'III',
				  four	=> 'IV', );

	   The difference between -vt=1 and -vt=2 is shown here:

	       # perltidy -lp -vt=1
	       $init->add(
			   mysprintf( "(void)find_threadsv(%s);",
				      cstring( $threadsv_names[ $op->targ ] )
			   )
	       );

	       # perltidy -lp -vt=2
	       $init->add( mysprintf( "(void)find_threadsv(%s);",
				      cstring( $threadsv_names[ $op->targ ] )
			   )
	       );

	   With -vt=1, the line ending in "add(" does not combine with the next line because the
	   next line is not balanced.  This can help with readability, but -vt=2 can be used to
	   ignore this rule.

	   The tightest, and least readable, code is produced with both "-vt=2" and "-vtc=2":

	       # perltidy -lp -vt=2 -vtc=2
	       $init->add( mysprintf( "(void)find_threadsv(%s);",
				      cstring( $threadsv_names[ $op->targ ] ) ) );

	   Notice how the code in all of these examples collapses vertically as -vt increases,
	   but the indentation remains unchanged.  This is because perltidy implements the -vt
	   parameter by first formatting as if -vt=0, and then simply overwriting one output line
	   on top of the next, if possible, to achieve the desired vertical tightness.	The -lp
	   indentation style has been designed to allow this vertical collapse to occur, which is
	   why it is required for the -vt parameter.

	   The -vt=n and -vtc=n parameters apply to each type of container token.  If desired,
	   vertical tightness controls can be applied independently to each of the closing
	   container token types.

	   The parameters for controlling parentheses are -pvt=n or --paren-vertical-tightness=n,
	   and -pcvt=n or --paren-vertical-tightness-closing=n.

	   Likewise, the parameters for square brackets are -sbvt=n or
	   --square-bracket-vertical-tightness=n, and -sbcvt=n or
	   --square-bracket-vertical-tightness-closing=n.

	   Finally, the parameters for controlling non-code block braces are -bvt=n or
	   --brace-vertical-tightness=n, and -bcvt=n or --brace-vertical-tightness-closing=n.

	   In fact, the parameter -vt=n is actually just an abbreviation for -pvt=n -bvt=n
	   sbvt=n, and likewise -vtc=n is an abbreviation for -pvtc=n -bvtc=n sbvtc=n.

       -bbvt=n or --block-brace-vertical-tightness=n
	   The -bbvt=n flag is just like the -vt=n flag but applies to opening code block braces.

	    -bbvt=0 break after opening block brace (default).
	    -bbvt=1 do not break unless this would produce more than one
		    step in indentation in a line.
	    -bbvt=2 do not break after opening block brace.

	   It is necessary to also use either -bl or -bli for this to work, because, as with
	   other vertical tightness controls, it is implemented by simply overwriting a line
	   ending with an opening block brace with the subsequent line.  For example:

	       # perltidy -bli -bbvt=0
	       if ( open( FILE, "< $File" ) )
		 {
		   while ( $File = <FILE> )
		     {
		       $In .= $File;
		       $count++;
		     }
		   close(FILE);
		 }

	       # perltidy -bli -bbvt=1
	       if ( open( FILE, "< $File" ) )
		 { while ( $File = <FILE> )
		     { $In .= $File;
		       $count++;
		     }
		   close(FILE);
		 }

	   By default this applies to blocks associated with keywords if, elsif, else, unless,
	   for, foreach, sub, while, until, and also with a preceding label.  This can be changed
	   with the parameter -bbvtl=string, or --block-brace-vertical-tightness-list=string,
	   where string is a space-separated list of block types.  For more information on the
	   possible values of this string, see "Specifying Block Types"

	   For example, if we want to just apply this style to "if", "elsif", and "else" blocks,
	   we could use "perltidy -bli -bbvt=1 -bbvtl='if elsif else'".

	   There is no vertical tightness control for closing block braces; with one exception
	   they they will be placed on separate lines.	The exception is that a cascade of
	   closing block braces may be stacked on a single line.  See -scbb.

       -sot,  --stack-opening-tokens and related flags
	   The -sot flag tells perltidy to "stack" opening tokens when possible to avoid lines
	   with isolated opening tokens.

	   For example:

	       # default
	       $opt_c = Text::CSV_XS->new(
		   {
		       binary	    => 1,
		       sep_char     => $opt_c,
		       always_quote => 1,
		   }
	       );

	       # -sot
	       $opt_c = Text::CSV_XS->new( {
		       binary	    => 1,
		       sep_char     => $opt_c,
		       always_quote => 1,
		   }
	       );

	   For detailed control of individual closing tokens the following controls can be used:

	     -sop  or --stack-opening-paren
	     -sohb or --stack-opening-hash-brace
	     -sosb or --stack-opening-square-bracket
	     -sobb or --stack-opening-block-brace

	   The flag -sot is an abbreviation for -sop -sohb -sosb.

	   The flag -sobb is a abbreviation for -bbvt=2 -bbvtl='*'.  This will case a cascade of
	   opening block braces to appear on a single line, although this an uncommon occurrence
	   except in test scripts.

       -sct,  --stack-closing-tokens and related flags
	   The -sct flag tells perltidy to "stack" closing tokens when possible to avoid lines
	   with isolated closing tokens.

	   For example:

	       # default
	       $opt_c = Text::CSV_XS->new(
		   {
		       binary	    => 1,
		       sep_char     => $opt_c,
		       always_quote => 1,
		   }
	       );

	       # -sct
	       $opt_c = Text::CSV_XS->new(
		   {
		       binary	    => 1,
		       sep_char     => $opt_c,
		       always_quote => 1,
		   } );

	   The -sct flag is somewhat similar to the -vtc flags, and in some cases it can give a
	   similar result.  The difference is that the -vtc flags try to avoid lines with leading
	   opening tokens by "hiding" them at the end of a previous line, whereas the -sct flag
	   merely tries to reduce the number of lines with isolated closing tokens by stacking
	   them but does not try to hide them.	For example:

	       # -vtc=2
	       $opt_c = Text::CSV_XS->new(
		   {
		       binary	    => 1,
		       sep_char     => $opt_c,
		       always_quote => 1, } );

	   For detailed control of the stacking of individual closing tokens the following
	   controls can be used:

	     -scp  or --stack-closing-paren
	     -schb or --stack-closing-hash-brace
	     -scsb or --stack-closing-square-bracket
	     -scbb or --stack-closing-block-brace

	   The flag -sct is an abbreviation for stacking the non-block closing tokens, -scp -schb
	   -scsb.

	   Stacking of closing block braces, -scbb, causes a cascade of isolated closing block
	   braces to be combined into a single line as in the following example:

	       # -scbb:
	       for $w1 (@w1) {
		   for $w2 (@w2) {
		       for $w3 (@w3) {
			   for $w4 (@w4) {
			       push( @lines, "$w1 $w2 $w3 $w4\n" );
			   } } } }

	   To simplify input even further for the case in which both opening and closing non-
	   block containers are stacked, the flag -sac or --stack-all-containers is an
	   abbreviation for -sot -sot.

       -dnl,  --delete-old-newlines
	   By default, perltidy first deletes all old line break locations, and then it looks for
	   good break points to match the desired line length.	Use -ndnl or
	   --nodelete-old-newlines to force perltidy to retain all old line break points.

       -anl,  --add-newlines
	   By default, perltidy will add line breaks when necessary to create continuations of
	   long lines and to improve the script appearance.  Use -nanl or --noadd-newlines to
	   prevent any new line breaks.

	   This flag does not prevent perltidy from eliminating existing line breaks; see
	   --freeze-newlines to completely prevent changes to line break points.

       Controlling whether perltidy breaks before or after operators
	   Four command line parameters provide some control over whether a line break should be
	   before or after specific token types.  Two parameters give detailed control:

	   -wba=s or --want-break-after=s, and

	   -wbb=s or --want-break-before=s.

	   These parameters are each followed by a quoted string, s, containing a list of token
	   types (separated only by spaces).  No more than one of each of these parameters should
	   be specified, because repeating a command-line parameter always overwrites the
	   previous one before perltidy ever sees it.

	   By default, perltidy breaks after these token types:
	     % + - * / x != == >= <= =~ !~ < >	| &
	     = **= += *= &= <<= &&= -= /= |= >>= ||= //= .= %= ^= x=

	   And perltidy breaks before these token types by default:
	     . << >> -> && || //

	   To illustrate, to cause a break after a concatenation operator, '.', rather than
	   before it, the command line would be

	     -wba="."

	   As another example, the following command would cause a break before math operators
	   '+', '-', '/', and '*':

	     -wbb="+ - / *"

	   These commands should work well for most of the token types that perltidy uses (use
	   --dump-token-types for a list).  Also try the -D flag on a short snippet of code and
	   look at the .DEBUG file to see the tokenization.  However, for a few token types there
	   may be conflicts with hardwired logic which cause unexpected results.  One example is
	   curly braces, which should be controlled with the parameter bl provided for that
	   purpose.

	   WARNING Be sure to put these tokens in quotes to avoid having them misinterpreted by
	   your command shell.

	   Two additional parameters are available which, though they provide no further
	   capability, can simplify input are:

	   -baao or --break-after-all-operators,

	   -bbao or --break-before-all-operators.

	   The -baao sets the default to be to break after all of the following operators:

	       % + - * / x != == >= <= =~ !~ < > | &
	       = **= += *= &= <<= &&= -= /= |= >>= ||= //= .= %= ^= x=
	       . : ? && || and or err xor

	   and the -bbao flag sets the default to break before all of these operators.	These can
	   be used to define an initial break preference which can be fine-tuned with the -wba
	   and -wbb flags.  For example, to break before all operators except an = one could use
	   --bbao -wba='=' rather than listing every single perl operator except = on a -wbb
	   flag.

   Controlling List Formatting
       Perltidy attempts to place comma-separated arrays of values in tables which look good.
       Its default algorithms usually work well, and they have been improving with each release,
       but several parameters are available to control list formatting.

       -boc,  --break-at-old-comma-breakpoints
	   This flag tells perltidy to try to break at all old commas.	This is not the default.
	   Normally, perltidy makes a best guess at list formatting, and seldom uses old comma
	   breakpoints.  Usually this works well, but consider:

	       my @list = (1,
			   1, 1,
			   1, 2, 1,
			   1, 3, 3, 1,
			   1, 4, 6, 4, 1,);

	   The default formatting will flatten this down to one line:

	       # perltidy (default)
	       my @list = ( 1, 1, 1, 1, 2, 1, 1, 3, 3, 1, 1, 4, 6, 4, 1, );

	   which hides the structure. Using -boc, plus additional flags to retain the original
	   style, yields

	       # perltidy -boc -lp -pt=2 -vt=1 -vtc=1
	       my @list = (1,
			   1, 1,
			   1, 2, 1,
			   1, 3, 3, 1,
			   1, 4, 6, 4, 1,);

	   A disadvantage of this flag is that all tables in the file must already be nicely
	   formatted.  For another possibility see the -fs flag in "Skipping Selected Sections of
	   Code".

       -mft=n,	--maximum-fields-per-table=n
	   If the computed number of fields for any table exceeds n, then it will be reduced to
	   n.  The default value for n is a large number, 40.  While this value should probably
	   be left unchanged as a general rule, it might be used on a small section of code to
	   force a list to have a particular number of fields per line, and then either the -boc
	   flag could be used to retain this formatting, or a single comment could be introduced
	   somewhere to freeze the formatting in future applications of perltidy.

	       # perltidy -mft=2
	       @month_of_year = (
		   'Jan', 'Feb',
		   'Mar', 'Apr',
		   'May', 'Jun',
		   'Jul', 'Aug',
		   'Sep', 'Oct',
		   'Nov', 'Dec'
	       );

       -cab=n,	--comma-arrow-breakpoints=n
	   A comma which follows a comma arrow, '=>', is given special consideration.  In a long
	   list, it is common to break at all such commas.  This parameter can be used to control
	   how perltidy breaks at these commas.  (However, it will have no effect if old comma
	   breaks are being forced because -boc is used).  The possible values of n are:

	    n=0 break at all commas after =>
	    n=1 stable: break at all commas after => if container is open,
		EXCEPT FOR one-line containers
	    n=2 break at all commas after =>, BUT try to form the maximum
		maximum one-line container lengths
	    n=3 do not treat commas after => specially at all
	    n=4 break everything: like n=0 but ALSO break a short container with
		a => not followed by a comma when -vt=0 is used
	    n=5 stable: like n=1 but ALSO break at open one-line containers when
		-vt=0 is used (default)

	   For example, given the following single line, perltidy by default will not add any
	   line breaks because it would break the existing one-line container:

	       bless { B => $B, Root => $Root } => $package;

	   Using -cab=0 will force a break after each comma-arrow item:

	       # perltidy -cab=0:
	       bless {
		   B	=> $B,
		   Root => $Root
	       } => $package;

	   If perltidy is subsequently run with this container broken, then by default it will
	   break after each '=>' because the container is now broken.  To reform a one-line
	   container, the parameter -cab=2 could be used.

	   The flag -cab=3 can be used to prevent these commas from being treated specially.  In
	   this case, an item such as "01" => 31 is treated as a single item in a table.  The
	   number of fields in this table will be determined by the same rules that are used for
	   any other table.  Here is an example.

	       # perltidy -cab=3
	       my %last_day = (
		   "01" => 31, "02" => 29, "03" => 31, "04" => 30,
		   "05" => 31, "06" => 30, "07" => 31, "08" => 31,
		   "09" => 30, "10" => 31, "11" => 30, "12" => 31
	       );

   Retaining or Ignoring Existing Line Breaks
       Several additional parameters are available for controlling the extent to which line
       breaks in the input script influence the output script.	In most cases, the default
       parameter values are set so that, if a choice is possible, the output style follows the
       input style.  For example, if a short logical container is broken in the input script,
       then the default behavior is for it to remain broken in the output script.

       Most of the parameters in this section would only be required for a one-time conversion of
       a script from short container lengths to longer container lengths.  The opposite effect,
       of converting long container lengths to shorter lengths, can be obtained by temporarily
       using a short maximum line length.

       -bol,  --break-at-old-logical-breakpoints
	   By default, if a logical expression is broken at a "&&", "||", "and", or "or", then
	   the container will remain broken.  Also, breaks at internal keywords "if" and "unless"
	   will normally be retained.  To prevent this, and thus form longer lines, use -nbol.

       -bok,  --break-at-old-keyword-breakpoints
	   By default, perltidy will retain a breakpoint before keywords which may return lists,
	   such as "sort" and <map>.  This allows chains of these operators to be displayed one
	   per line.  Use -nbok to prevent retaining these breakpoints.

       -bot,  --break-at-old-ternary-breakpoints
	   By default, if a conditional (ternary) operator is broken at a ":", then it will
	   remain broken.  To prevent this, and thereby form longer lines, use -nbot.

       -boa,  --break-at-old-attribute-breakpoints
	   By default, if an attribute list is broken at a ":" in the source file, then it will
	   remain broken.  For example, given the following code, the line breaks at the ':'s
	   will be retained:

			       my @field
				 : field
				 : Default(1)
				 : Get('Name' => 'foo') : Set('Name');

	   If the attributes are on a single line in the source code then they will remain on a
	   single line if possible.

	   To prevent this, and thereby always form longer lines, use -nboa.

       -iob,  --ignore-old-breakpoints
	   Use this flag to tell perltidy to ignore existing line breaks to the maximum extent
	   possible.  This will tend to produce the longest possible containers, regardless of
	   type, which do not exceed the line length limit.

       -kis,  --keep-interior-semicolons
	   Use the -kis flag to prevent breaking at a semicolon if there was no break there in
	   the input file.  Normally perltidy places a newline after each semicolon which
	   terminates a statement unless several statements are contained within a one-line brace
	   block.  To illustrate, consider the following input lines:

	       dbmclose(%verb_delim); undef %verb_delim;
	       dbmclose(%expanded); undef %expanded;

	   The default is to break after each statement, giving

	       dbmclose(%verb_delim);
	       undef %verb_delim;
	       dbmclose(%expanded);
	       undef %expanded;

	   With perltidy -kis the multiple statements are retained:

	       dbmclose(%verb_delim); undef %verb_delim;
	       dbmclose(%expanded);   undef %expanded;

	   The statements are still subject to the specified value of maximum-line-length and
	   will be broken if this maximum is exceeed.

   Blank Line Control
       Blank lines can improve the readability of a script if they are carefully placed.
       Perltidy has several commands for controlling the insertion, retention, and removal of
       blank lines.

       -fbl,  --freeze-blank-lines
	   Set -fbl if you want to the blank lines in your script to remain exactly as they are.
	   The rest of the parameters in this section may then be ignored.  (Note: setting the
	   -fbl flag is equivalent to setting -mbl=0 and -kbl=2).

       -bbc,  --blanks-before-comments
	   A blank line will be introduced before a full-line comment.	This is the default.  Use
	   -nbbc or  --noblanks-before-comments to prevent such blank lines from being
	   introduced.

       -blbs=n,  --blank-lines-before-subs=n
	   The parameter -blbs=n requests that least n blank lines precede a sub definition which
	   does not follow a comment and which is more than one-line long.  The default is
	   <-blbs=1>.  BEGIN and END blocks are included.

	   The requested number of blanks statement will be inserted regardless of of the value
	   of --maximum-consecutive-blank-lines=n (-mbl=n) with the exception that if -mbl=0 then
	   no blanks will be output.

	   This parameter interacts with the value k of the parameter
	   --maximum-consecutive-blank-lines=k (-mbl=k) as follows:

	   1. If -mbl=0 then no blanks will be output.	This allows all blanks to be suppressed
	   with a single parameter.  Otherwise,

	   2. If the number of old blank lines in the script is less than n then additional
	   blanks will be inserted to make the total n regardless of the value of -mbl=k.

	   3. If the number of old blank lines in the script equals or exceeds n then this
	   parameter has no effect, however the total will not exceed value specified on the
	   -mbl=k flag.

       -blbp=n,  --blank-lines-before-packages=n
	   The parameter -blbp=n requests that least n blank lines precede a package which does
	   not follow a comment.  The default is <-blbp=1>.

	   This parameter interacts with the value k of the parameter
	   --maximum-consecutive-blank-lines=k (-mbl=k) in the same way as described for the
	   previous item -blbs=n.

       -bbs,  --blanks-before-subs
	   For compatibility with previous versions, -bbs or --blanks-before-subs is equivalent
	   to -blbp=1 and -blbs=1.

	   Likewise, -nbbs or --noblanks-before-subs is equivalent to -blbp=0 and -blbs=0.

       -bbb,  --blanks-before-blocks
	   A blank line will be introduced before blocks of coding delimited by for, foreach,
	   while, until, and if, unless, in the following circumstances:

	   o   The block is not preceded by a comment.

	   o   The block is not a one-line block.

	   o   The number of consecutive non-blank lines at the current indentation depth is at
	       least -lbl (see next section).

	   This is the default.  The intention of this option is to introduce some space within
	   dense coding.  This is negated with -nbbb or  --noblanks-before-blocks.

       -lbl=n --long-block-line-count=n
	   This controls how often perltidy is allowed to add blank lines before certain block
	   types (see previous section).  The default is 8.  Entering a value of 0 is equivalent
	   to entering a very large number.

       -mbl=n --maximum-consecutive-blank-lines=n
	   This parameter specifies the maximum number of consecutive blank lines which will be
	   output within code sections of a script.  The default is n=1.  If the input file has
	   more than n consecutive blank lines, the number will be reduced to n except as noted
	   above for the -blbp and -blbs parameters.  If n=0 then no blank lines will be output
	   (unless all old blank lines are retained with the -kbl=2 flag of the next section).

	   This flag obviously does not apply to pod sections, here-documents, and quotes.

       -kbl=n,	--keep-old-blank-lines=n
	   The -kbl=n flag gives you control over how your existing blank lines are treated.

	   The possible values of n are:

	    n=0 ignore all old blank lines
	    n=1 stable: keep old blanks, but limited by the value of the B<-mbl=n> flag
	    n=2 keep all old blank lines, regardless of the value of the B<-mbl=n> flag

	   The default is n=1.

       -sob,  --swallow-optional-blank-lines
	   This is equivalent to kbl=0 and is included for compatibility with previous versions.

       -nsob,  --noswallow-optional-blank-lines
	   This is equivalent to kbl=1 and is included for compatibility with previous versions.

   Styles
       A style refers to a convenient collection of existing parameters.

       -gnu, --gnu-style
	   -gnu gives an approximation to the GNU Coding Standards (which do not apply to perl)
	   as they are sometimes implemented.  At present, this style overrides the default style
	   with the following parameters:

	       -lp -bl -noll -pt=2 -bt=2 -sbt=2 -icp

       -pbp, --perl-best-practices
	   -pbp is an abbreviation for the parameters in the book Perl Best Practices by Damian
	   Conway:

	       -l=78 -i=4 -ci=4 -st -se -vt=2 -cti=0 -pt=1 -bt=1 -sbt=1 -bbt=1 -nsfs -nolq
	       -wbb="% + - * / x != == >= <= =~ !~ < > | & =
		     **= += *= &= <<= &&= -= /= |= >>= ||= //= .= %= ^= x="

	   Please note that this parameter set includes -st and -se flags, which make perltidy
	   act as a filter on one file only.  These can be overridden by placing -nst and/or -nse
	   after the -pbp parameter.

	   Also note that the value of continuation indentation, -ci=4, is equal to the value of
	   the full indentation, -i=4.	In some complex statements perltidy will produce nicer
	   results with -ci=2. This can be implemented by including -ci=2 after the -pbp
	   parameter.  For example,

	       # perltidy -pbp
	       $self->{_text} = (
		    !$section	     ? ''
		   : $type eq 'item' ? "the $section entry"
		   :		       "the section on $section"
		   )
		   . (
		   $page
		   ? ( $section ? ' in ' : '' ) . "the $page$page_ext manpage"
		   : ' elsewhere in this document'
		   );

	       # perltidy -pbp -ci=2
	       $self->{_text} = (
		    !$section	     ? ''
		   : $type eq 'item' ? "the $section entry"
		   :		       "the section on $section"
		 )
		 . (
		   $page
		   ? ( $section ? ' in ' : '' ) . "the $page$page_ext manpage"
		   : ' elsewhere in this document'
		 );

   Other Controls
       Deleting selected text
	   Perltidy can selectively delete comments and/or pod documentation.  The command -dac
	   or  --delete-all-comments will delete all comments and all pod documentation, leaving
	   just code and any leading system control lines.

	   The command -dp or --delete-pod will remove all pod documentation (but not comments).

	   Two commands which remove comments (but not pod) are: -dbc or --delete-block-comments
	   and -dsc or	--delete-side-comments.  (Hanging side comments will be deleted with
	   block comments here.)

	   The negatives of these commands also work, and are the defaults.  When block comments
	   are deleted, any leading 'hash-bang' will be retained.  Also, if the -x flag is used,
	   any system commands before a leading hash-bang will be retained (even if they are in
	   the form of comments).

       Writing selected text to a file
	   When perltidy writes a formatted text file, it has the ability to also send selected
	   text to a file with a .TEE extension.  This text can include comments and pod
	   documentation.

	   The command -tac or	--tee-all-comments will write all comments and all pod
	   documentation.

	   The command -tp or --tee-pod will write all pod documentation (but not comments).

	   The commands which write comments (but not pod) are: -tbc or --tee-block-comments and
	   -tsc or  --tee-side-comments.  (Hanging side comments will be written with block
	   comments here.)

	   The negatives of these commands also work, and are the defaults.

       Using a .perltidyrc command file
	   If you use perltidy frequently, you probably won't be happy until you create a
	   .perltidyrc file to avoid typing commonly-used parameters.  Perltidy will first look
	   in your current directory for a command file named .perltidyrc.  If it does not find
	   one, it will continue looking for one in other standard locations.

	   These other locations are system-dependent, and may be displayed with the command
	   "perltidy -dpro".  Under Unix systems, it will first look for an environment variable
	   PERLTIDY.  Then it will look for a .perltidyrc file in the home directory, and then
	   for a system-wide file /usr/local/etc/perltidyrc, and then it will look for
	   /etc/perltidyrc.  Note that these last two system-wide files do not have a leading
	   dot.  Further system-dependent information will be found in the INSTALL file
	   distributed with perltidy.

	   Under Windows, perltidy will also search for a configuration file named perltidy.ini
	   since Windows does not allow files with a leading period (.).  Use "perltidy -dpro" to
	   see the possbile locations for your system.	An example might be C:\Documents and
	   Settings\All Users\perltidy.ini.

	   Another option is the use of the PERLTIDY environment variable.  The method for
	   setting environment variables depends upon the version of Windows that you are using.
	   Instructions for Windows 95 and later versions can be found here:

	   http://www.netmanage.com/000/20021101_005_tcm21-6336.pdf

	   Under Windows NT / 2000 / XP the PERLTIDY environment variable can be placed in either
	   the user section or the system section.  The later makes the configuration file common
	   to all users on the machine.  Be sure to enter the full path of the configuration file
	   in the value of the environment variable.  Ex.  PERLTIDY=C:\Documents and
	   Settings\perltidy.ini

	   The configuation file is free format, and simply a list of parameters, just as they
	   would be entered on a command line.	Any number of lines may be used, with any number
	   of parameters per line, although it may be easiest to read with one parameter per
	   line.  Comment text begins with a #, and there must also be a space before the # for
	   side comments.  It is a good idea to put complex parameters in either single or double
	   quotes.

	   Here is an example of a .perltidyrc file:

	     # This is a simple of a .perltidyrc configuration file
	     # This implements a highly spaced style
	     -se    # errors to standard error output
	     -w     # show all warnings
	     -bl    # braces on new lines
	     -pt=0  # parens not tight at all
	     -bt=0  # braces not tight
	     -sbt=0 # square brackets not tight

	   The parameters in the .perltidyrc file are installed first, so any parameters given on
	   the command line will have priority over them.

	   To avoid confusion, perltidy ignores any command in the .perltidyrc file which would
	   cause some kind of dump and an exit.  These are:

	    -h -v -ddf -dln -dop -dsn -dtt -dwls -dwrs -ss

	   There are several options may be helpful in debugging a .perltidyrc file:

	   o   A very helpful command is --dump-profile or -dpro.  It writes a list of all
	       configuration filenames tested to standard output, and if a file is found, it
	       dumps the content to standard output before exiting.  So, to find out where
	       perltidy looks for its configuration files, and which one if any it selects, just
	       enter

		 perltidy -dpro

	   o   It may be simplest to develop and test configuration files with alternative names,
	       and invoke them with -pro=filename on the command line.	Then rename the desired
	       file to .perltidyrc when finished.

	   o   The parameters in the .perltidyrc file can be switched off with the -npro option.

	   o   The commands --dump-options, --dump-defaults, --dump-long-names, and
	       --dump-short-names, all described below, may all be helpful.

       Creating a new abbreviation
	   A special notation is available for use in a .perltidyrc file for creating an
	   abbreviation for a group of options.  This can be used to create a shorthand for one
	   or more styles which are frequently, but not always, used.  The notation is to group
	   the options within curly braces which are preceded by the name of the alias (without
	   leading dashes), like this:

		   newword {
		   -opt1
		   -opt2
		   }

	   where newword is the abbreviation, and opt1, etc, are existing parameters or other
	   abbreviations.  The main syntax requirement is that the new abbreviation must begin on
	   a new line.	Space before and after the curly braces is optional.  For a specific
	   example, the following line

		   airy {-bl -pt=0 -bt=0 -sbt=0}

	   could be placed in a .perltidyrc file, and then invoked at will with

		   perltidy -airy somefile.pl

	   (Either "-airy" or "--airy" may be used).

       Skipping leading non-perl commands with -x or --look-for-hash-bang
	   If your script has leading lines of system commands or other text which are not valid
	   perl code, and which are separated from the start of the perl code by a "hash-bang"
	   line, ( a line of the form "#!...perl" ), you must use the -x flag to tell perltidy
	   not to parse and format any lines before the "hash-bang" line.  This option also
	   invokes perl with a -x flag when checking the syntax.  This option was originally
	   added to allow perltidy to parse interactive VMS scripts, but it should be used for
	   any script which is normally invoked with "perl -x".

       Making a file unreadable
	   The goal of perltidy is to improve the readability of files, but there are two
	   commands which have the opposite effect, --mangle and --extrude.  They are actually
	   merely aliases for combinations of other parameters.  Both of these strip all possible
	   whitespace, but leave comments and pod documents, so that they are essentially
	   reversible.	The difference between these is that --mangle puts the fewest possible
	   line breaks in a script while --extrude puts the maximum possible.  Note that these
	   options do not provided any meaningful obfuscation, because perltidy can be used to
	   reformat the files.	They were originally developed to help test the tokenization
	   logic of perltidy, but they have other uses.  One use for --mangle is the following:

	     perltidy --mangle myfile.pl -st | perltidy -o myfile.pl.new

	   This will form the maximum possible number of one-line blocks (see next section), and
	   can sometimes help clean up a badly formatted script.

	   A similar technique can be used with --extrude instead of --mangle to make the minimum
	   number of one-line blocks.

	   Another use for --mangle is to combine it with -dac to reduce the file size of a perl
	   script.

       One-line blocks
	   There are a few points to note regarding one-line blocks.  A one-line block is
	   something like this,

		   if ($x > 0) { $y = 1 / $x }

	   where the contents within the curly braces is short enough to fit on a single line.

	   With few exceptions, perltidy retains existing one-line blocks, if it is possible
	   within the line-length constraint, but it does not attempt to form new ones.  In other
	   words, perltidy will try to follow the one-line block style of the input file.

	   If an existing one-line block is longer than the maximum line length, however, it will
	   be broken into multiple lines.  When this happens, perltidy checks for and adds any
	   optional terminating semicolon (unless the -nasc option is used) if the block is a
	   code block.

	   The main exception is that perltidy will attempt to form new one-line blocks following
	   the keywords "map", "eval", and "sort", because these code blocks are often small and
	   most clearly displayed in a single line.

	   One-line block rules can conflict with the cuddled-else option.  When the cuddled-else
	   option is used, perltidy retains existing one-line blocks, even if they do not obey
	   cuddled-else formatting.

	   Occasionally, when one-line blocks get broken because they exceed the available line
	   length, the formatting will violate the requested brace style.  If this happens,
	   reformatting the script a second time should correct the problem.

       Debugging
	   The following flags are available for debugging:

	   --dump-defaults or -ddf will write the default option set to standard output and quit

	   --dump-profile or -dpro  will write the name of the current configuration file and its
	   contents to standard output and quit.

	   --dump-options or -dop  will write current option set to standard output and quit.

	   --dump-long-names or -dln  will write all command line long names (passed to
	   Get_options) to standard output and quit.

	   --dump-short-names  or -dsn will write all command line short names to standard output
	   and quit.

	   --dump-token-types or -dtt  will write a list of all token types to standard output
	   and quit.

	   --dump-want-left-space or -dwls  will write the hash %want_left_space to standard
	   output and quit.  See the section on controlling whitespace around tokens.

	   --dump-want-right-space or -dwrs  will write the hash %want_right_space to standard
	   output and quit.  See the section on controlling whitespace around tokens.

	   --no-memoize or -nmem  will turn of memoizing.  Memoization can reduce run time when
	   running perltidy repeatedly in a single process.  It is on by default but can be
	   deactivated for testing with -nmem.

	   -DEBUG  will write a file with extension .DEBUG for each input file showing the
	   tokenization of all lines of code.

       Working with MakeMaker, AutoLoader and SelfLoader
	   The first $VERSION line of a file which might be eval'd by MakeMaker is passed through
	   unchanged except for indentation.  Use --nopass-version-line, or -npvl, to deactivate
	   this feature.

	   If the AutoLoader module is used, perltidy will continue formatting code after seeing
	   an __END__ line.  Use --nolook-for-autoloader, or -nlal, to deactivate this feature.

	   Likewise, if the SelfLoader module is used, perltidy will continue formatting code
	   after seeing a __DATA__ line.  Use --nolook-for-selfloader, or -nlsl, to deactivate
	   this feature.

       Working around problems with older version of Perl
	   Perltidy contains a number of rules which help avoid known subtleties and problems
	   with older versions of perl, and these rules always take priority over whatever
	   formatting flags have been set.  For example, perltidy will usually avoid starting a
	   new line with a bareword, because this might cause problems if "use strict" is active.

	   There is no way to override these rules.

HTML OPTIONS
       The -html master switch
	   The flag -html causes perltidy to write an html file with extension .html.  So, for
	   example, the following command

		   perltidy -html somefile.pl

	   will produce a syntax-colored html file named somefile.pl.html which may be viewed
	   with a browser.

	   Please Note: In this case, perltidy does not do any formatting to the input file, and
	   it does not write a formatted file with extension .tdy.  This means that two perltidy
	   runs are required to create a fully reformatted, html copy of a script.

       The -pre flag for code snippets
	   When the -pre flag is given, only the pre-formatted section, within the <PRE> and
	   </PRE> tags, will be output.  This simplifies inclusion of the output in other files.
	   The default is to output a complete web page.

       The -nnn flag for line numbering
	   When the -nnn flag is given, the output lines will be numbered.

       The -toc, or --html-table-of-contents flag
	   By default, a table of contents to packages and subroutines will be written at the
	   start of html output.  Use -ntoc to prevent this.  This might be useful, for example,
	   for a pod document which contains a number of unrelated code snippets.  This flag only
	   influences the code table of contents; it has no effect on any table of contents
	   produced by pod2html (see next item).

       The -pod, or --pod2html flag
	   There are two options for formatting pod documentation.  The default is to pass the
	   pod through the Pod::Html module (which forms the basis of the pod2html utility).  Any
	   code sections are formatted by perltidy, and the results then merged.  Note: perltidy
	   creates a temporary file when Pod::Html is used; see "FILES".  Also, Pod::Html creates
	   temporary files for its cache.

	   NOTE: Perltidy counts the number of "=cut" lines, and either moves the pod text to the
	   top of the html file if there is one "=cut", or leaves the pod text in its original
	   order (interleaved with code) otherwise.

	   Most of the flags accepted by pod2html may be included in the perltidy command line,
	   and they will be passed to pod2html.  In some cases, the flags have a prefix "pod" to
	   emphasize that they are for the pod2html, and this prefix will be removed before they
	   are passed to pod2html.  The flags which have the additional "pod" prefix are:

	      --[no]podheader --[no]podindex --[no]podrecurse --[no]podquiet
	      --[no]podverbose --podflush

	   The flags which are unchanged from their use in pod2html are:

	      --backlink=s --cachedir=s --htmlroot=s --libpods=s --title=s
	      --podpath=s --podroot=s

	   where 's' is an appropriate character string.  Not all of these flags are available in
	   older versions of Pod::Html.  See your Pod::Html documentation for more information.

	   The alternative, indicated with -npod, is not to use Pod::Html, but rather to format
	   pod text in italics (or whatever the stylesheet indicates), without special html
	   markup.  This is useful, for example, if pod is being used as an alternative way to
	   write comments.

       The -frm, or --frames flag
	   By default, a single html output file is produced.  This can be changed with the -frm
	   option, which creates a frame holding a table of contents in the left panel and the
	   source code in the right side. This simplifies code browsing.  Assume, for example,
	   that the input file is MyModule.pm.	Then, for default file extension choices, these
	   three files will be created:

	    MyModule.pm.html	  - the frame
	    MyModule.pm.toc.html  - the table of contents
	    MyModule.pm.src.html  - the formatted source code

	   Obviously this file naming scheme requires that output be directed to a real file (as
	   opposed to, say, standard output).  If this is not the case, or if the file extension
	   is unknown, the -frm option will be ignored.

       The -text=s, or --html-toc-extension flag
	   Use this flag to specify the extra file extension of the table of contents file when
	   html frames are used.  The default is "toc".  See "Specifying File Extensions".

       The -sext=s, or --html-src-extension flag
	   Use this flag to specify the extra file extension of the content file when html frames
	   are used.  The default is "src".  See "Specifying File Extensions".

       The -hent, or --html-entities flag
	   This flag controls the use of Html::Entities for html formatting.  By default, the
	   module Html::Entities is used to encode special symbols.  This may not be the right
	   thing for some browser/language combinations.  Use --nohtml-entities or -nhent to
	   prevent this.

       Style Sheets
	   Style sheets make it very convenient to control and adjust the appearance of html
	   pages.  The default behavior is to write a page of html with an embedded style sheet.

	   An alternative to an embedded style sheet is to create a page with a link to an
	   external style sheet.  This is indicated with the -css=filename,  where the external
	   style sheet is filename.  The external style sheet filename will be created if and
	   only if it does not exist.  This option is useful for controlling multiple pages from
	   a single style sheet.

	   To cause perltidy to write a style sheet to standard output and exit, use the -ss, or
	   --stylesheet, flag.	This is useful if the style sheet could not be written for some
	   reason, such as if the -pre flag was used.  Thus, for example,

	     perltidy -html -ss >mystyle.css

	   will write a style sheet with the default properties to file mystyle.css.

	   The use of style sheets is encouraged, but a web page without a style sheets can be
	   created with the flag -nss.	Use this option if you must to be sure that older
	   browsers (roughly speaking, versions prior to 4.0 of Netscape Navigator and Internet
	   Explorer) can display the syntax-coloring of the html files.

       Controlling HTML properties
	   Note: It is usually more convenient to accept the default properties and then edit the
	   stylesheet which is produced.  However, this section shows how to control the
	   properties with flags to perltidy.

	   Syntax colors may be changed from their default values by flags of the either the long
	   form, -html-color-xxxxxx=n, or more conveniently the short form, -hcx=n, where xxxxxx
	   is one of the following words, and x is the corresponding abbreviation:

		 Token Type		xxxxxx		 x
		 ----------		--------	 --
		 comment		comment 	 c
		 number 		numeric 	 n
		 identifier		identifier	 i
		 bareword, function	bareword	 w
		 keyword		keyword 	 k
		 quite, pattern 	quote		 q
		 here doc text		here-doc-text	 h
		 here doc target	here-doc-target  hh
		 punctuation		punctuation	 pu
		 parentheses		paren		 p
		 structural braces	structure	 s
		 semicolon		semicolon	 sc
		 colon			colon		 co
		 comma			comma		 cm
		 label			label		 j
		 sub definition name	subroutine	 m
		 pod text		pod-text	 pd

	   A default set of colors has been defined, but they may be changed by providing values
	   to any of the following parameters, where n is either a 6 digit hex RGB color value or
	   an ascii name for a color, such as 'red'.

	   To illustrate, the following command will produce an html file somefile.pl.html with
	   "aqua" keywords:

		   perltidy -html -hck=00ffff somefile.pl

	   and this should be equivalent for most browsers:

		   perltidy -html -hck=aqua somefile.pl

	   Perltidy merely writes any non-hex names that it sees in the html file.  The following
	   16 color names are defined in the HTML 3.2 standard:

		   black   => 000000,
		   silver  => c0c0c0,
		   gray    => 808080,
		   white   => ffffff,
		   maroon  => 800000,
		   red	   => ff0000,
		   purple  => 800080,
		   fuchsia => ff00ff,
		   green   => 008000,
		   lime    => 00ff00,
		   olive   => 808000,
		   yellow  => ffff00
		   navy    => 000080,
		   blue    => 0000ff,
		   teal    => 008080,
		   aqua    => 00ffff,

	   Many more names are supported in specific browsers, but it is safest to use the hex
	   codes for other colors.  Helpful color tables can be located with an internet search
	   for "HTML color tables".

	   Besides color, two other character attributes may be set: bold, and italics.  To set a
	   token type to use bold, use the flag --html-bold-xxxxxx or -hbx, where xxxxxx or x are
	   the long or short names from the above table.  Conversely, to set a token type to NOT
	   use bold, use --nohtml-bold-xxxxxx or -nhbx.

	   Likewise, to set a token type to use an italic font, use the flag --html-italic-xxxxxx
	   or -hix, where again xxxxxx or x are the long or short names from the above table.
	   And to set a token type to NOT use italics, use --nohtml-italic-xxxxxx or -nhix.

	   For example, to use bold braces and lime color, non-bold, italics keywords the
	   following command would be used:

		   perltidy -html -hbs -hck=00FF00 -nhbk -hik somefile.pl

	   The background color can be specified with --html-color-background=n, or -hcbg=n for
	   short, where n is a 6 character hex RGB value.  The default color of text is the value
	   given to punctuation, which is black as a default.

	   Here are some notes and hints:

	   1. If you find a preferred set of these parameters, you may want to create a
	   .perltidyrc file containing them.  See the perltidy man page for an explanation.

	   2. Rather than specifying values for these parameters, it is probably easier to accept
	   the defaults and then edit a style sheet.  The style sheet contains comments which
	   should make this easy.

	   3. The syntax-colored html files can be very large, so it may be best to split large
	   files into smaller pieces to improve download times.

SOME COMMON INPUT CONVENTIONS
   Specifying Block Types
       Several parameters which refer to code block types may be customized by also specifying an
       associated list of block types.	The type of a block is the name of the keyword which
       introduces that block, such as if, else, or sub.  An exception is a labeled block, which
       has no keyword, and should be specified with just a colon.  To specify all blocks use '*'.

       For example, the following parameter specifies "sub", labels, "BEGIN", and "END" blocks:

	  -cscl="sub : BEGIN END"

       (the meaning of the -cscl parameter is described above.)  Note that quotes are required
       around the list of block types because of the spaces.  For another example, the following
       list specifies all block types for vertical tightness:

	  -bbvtl='*'

   Specifying File Extensions
       Several parameters allow default file extensions to be overridden.  For example, a backup
       file extension may be specified with -bext=ext, where ext is some new extension.  In order
       to provides the user some flexibility, the following convention is used in all cases to
       decide if a leading '.' should be used.	If the extension "ext" begins with "A-Z", "a-z",
       or "0-9", then it will be appended to the filename with an intermediate '.' (or perhaps an
       '_' on VMS systems).  Otherwise, it will be appended directly.

       For example, suppose the file is somefile.pl.  For "-bext=old", a '.' is added to give
       somefile.pl.old.  For "-bext=.old", no additional '.' is added, so again the backup file
       is somefile.pl.old.  For "-bext=~", then no dot is added, and the backup file will be
       somefile.pl~  .

SWITCHES WHICH MAY BE NEGATED
       The following list shows all short parameter names which allow a prefix 'n' to produce the
       negated form:

	D    anl asc  aws  b	bbb bbc bbs  bl   bli  boc bok	bol  bot  ce
	csc  dac dbc  dcsc ddf	dln dnl dop  dp   dpro dsc dsm	dsn  dtt  dwls
	dwrs dws f    fll  frm	fs  hsc html ibc  icb  icp iob	isbc lal  log
	lp   lsl ohbr okw  ola	oll opr opt  osbr otr  ple ple	pod  pvl  q
	sbc  sbl schb scp  scsb sct se	sfp  sfs  skp  sob sohb sop  sosb sot
	ssc  st  sts  syn  t	tac tbc toc  tp   tqw  tsc w	x    bar  kis

       Equivalently, the prefix 'no' or 'no-' on the corresponding long names may be used.

LIMITATIONS
       Parsing Limitations
	   Perltidy should work properly on most perl scripts.	It does a lot of self-checking,
	   but still, it is possible that an error could be introduced and go undetected.
	   Therefore, it is essential to make careful backups and to test reformatted scripts.

	   The main current limitation is that perltidy does not scan modules included with 'use'
	   statements.	This makes it necessary to guess the context of any bare words introduced
	   by such modules.  Perltidy has good guessing algorithms, but they are not infallible.
	   When it must guess, it leaves a message in the log file.

	   If you encounter a bug, please report it.

       What perltidy does not parse and format
	   Perltidy indents but does not reformat comments and "qw" quotes.  Perltidy does not in
	   any way modify the contents of here documents or quoted text, even if they contain
	   source code.  (You could, however, reformat them separately).  Perltidy does not
	   format 'format' sections in any way.  And, of course, it does not modify pod
	   documents.

FILES
       Temporary files
	   Under the -html option with the default --pod2html flag, a temporary file is required
	   to pass text to Pod::Html.  Unix systems will try to use the POSIX tmpnam() function.
	   Otherwise the file perltidy.TMP will be temporarily created in the current working
	   directory.

       Special files when standard input is used
	   When standard input is used, the log file, if saved, is perltidy.LOG, and any errors
	   are written to perltidy.ERR unless the -se flag is set.  These are saved in the
	   current working directory.

       Files overwritten
	   The following file extensions are used by perltidy, and files with these extensions
	   may be overwritten or deleted: .ERR, .LOG, .TEE, and/or .tdy, .html, and .bak,
	   depending on the run type and settings.

       Files extensions limitations
	   Perltidy does not operate on files for which the run could produce a file with a
	   duplicated file extension.  These extensions include .LOG, .ERR, .TEE, and perhaps
	   .tdy and .bak, depending on the run type.  The purpose of this rule is to prevent
	   generating confusing filenames such as somefile.tdy.tdy.tdy.
