       pod2man - Convert POD data to formatted *roff input

       pod2man [--center=string] [--date=string]
	   [--fixed=font] [--fixedbold=font] [--fixeditalic=font]
	   [--fixedbolditalic=font] [--name=name] [--official]
	   [--quotes=quotes] [--release[=version]]
	   [--section=manext] [--stderr] [--utf8] [--verbose]
	   [input [output] ...]

       pod2man --help

       pod2man is a front-end for Pod::Man, using it to generate *roff input from POD source.
       The resulting *roff code is suitable for display on a terminal using nroff(1), normally
       via man(1), or printing using troff(1).

       input is the file to read for POD source (the POD can be embedded in code).  If input
       isn't given, it defaults to "STDIN".  output, if given, is the file to which to write the
       formatted output.  If output isn't given, the formatted output is written to "STDOUT".
       Several POD files can be processed in the same pod2man invocation (saving module load and
       compile times) by providing multiple pairs of input and output files on the command line.

       --section, --release, --center, --date, and --official can be used to set the headers and
       footers to use; if not given, Pod::Man will assume various defaults.  See below or
       Pod::Man for details.

       pod2man assumes that your *roff formatters have a fixed-width font named "CW".  If yours
       is called something else (like "CR"), use --fixed to specify it.  This generally only
       matters for troff output for printing.  Similarly, you can set the fonts used for bold,
       italic, and bold italic fixed-width output.

       Besides the obvious pod conversions, Pod::Man, and therefore pod2man also takes care of
       formatting func(), func(n), and simple variable references like $foo or @bar so you don't
       have to use code escapes for them; complex expressions like $fred{'stuff'} will still need
       to be escaped, though.  It also translates dashes that aren't used as hyphens into en
       dashes, makes long dashes--like this--into proper em dashes, fixes "paired quotes," and
       takes care of several other troff-specific tweaks.  See Pod::Man for complete information.

       -c string, --center=string
	   Sets the centered page header to string.  The default is "User Contributed Perl
	   Documentation", but also see --official below.

       -d string, --date=string
	   Set the left-hand footer string to this value.  By default, the modification date of
	   the input file will be used, or the current date if input comes from "STDIN".

	   The fixed-width font to use for verbatim text and code.  Defaults to "CW".  Some
	   systems may want "CR" instead.  Only matters for troff(1) output.

	   Bold version of the fixed-width font.  Defaults to "CB".  Only matters for troff(1)

	   Italic version of the fixed-width font (actually, something of a misnomer, since most
	   fixed-width fonts only have an oblique version, not an italic version).  Defaults to
	   "CI".  Only matters for troff(1) output.

	   Bold italic (probably actually oblique) version of the fixed-width font.  Pod::Man
	   doesn't assume you have this, and defaults to "CB".	Some systems (such as Solaris)
	   have this font available as "CX".  Only matters for troff(1) output.

       -h, --help
	   Print out usage information.

       -l, --lax
	   No longer used.  pod2man used to check its input for validity as a manual page, but
	   this should now be done by podchecker(1) instead.  Accepted for backward
	   compatibility; this option no longer does anything.

       -n name, --name=name
	   Set the name of the manual page to name.  Without this option, the manual name is set
	   to the uppercased base name of the file being converted unless the manual section is
	   3, in which case the path is parsed to see if it is a Perl module path.  If it is, a
	   path like ".../lib/Pod/Man.pm" is converted into a name like "Pod::Man".  This option,
	   if given, overrides any automatic determination of the name.

	   Note that this option is probably not useful when converting multiple POD files at
	   once.  The convention for Unix man pages for commands is for the man page title to be
	   in all-uppercase even if the command isn't.

       -o, --official
	   Set the default header to indicate that this page is part of the standard Perl
	   release, if --center is not also given.

       -q quotes, --quotes=quotes
	   Sets the quote marks used to surround C<> text to quotes.  If quotes is a single
	   character, it is used as both the left and right quote; if quotes is two characters,
	   the first character is used as the left quote and the second as the right quoted; and
	   if quotes is four characters, the first two are used as the left quote and the second
	   two as the right quote.

	   quotes may also be set to the special value "none", in which case no quote marks are
	   added around C<> text (but the font is still changed for troff output).

       -r, --release
	   Set the centered footer.  By default, this is the version of Perl you run pod2man
	   under.  Note that some system an macro sets assume that the centered footer will be a
	   modification date and will prepend something like "Last modified: "; if this is the
	   case, you may want to set --release to the last modified date and --date to the
	   version number.

       -s, --section
	   Set the section for the ".TH" macro.  The standard section numbering convention is to
	   use 1 for user commands, 2 for system calls, 3 for functions, 4 for devices, 5 for
	   file formats, 6 for games, 7 for miscellaneous information, and 8 for administrator
	   commands.  There is a lot of variation here, however; some systems (like Solaris) use
	   4 for file formats, 5 for miscellaneous information, and 7 for devices.  Still others
	   use 1m instead of 8, or some mix of both.  About the only section numbers that are
	   reliably consistent are 1, 2, and 3.

	   By default, section 1 will be used unless the file ends in ".pm", in which case
	   section 3 will be selected.

	   By default, pod2man puts any errors detected in the POD input in a POD ERRORS section
	   in the output manual page.  If --stderr is given, errors are sent to standard error
	   instead and the POD ERRORS section is suppressed.

       -u, --utf8
	   By default, pod2man produces the most conservative possible *roff output to try to
	   ensure that it will work with as many different *roff implementations as possible.
	   Many *roff implementations cannot handle non-ASCII characters, so this means all non-
	   ASCII characters are converted either to a *roff escape sequence that tries to create
	   a properly accented character (at least for troff output) or to "X".

	   This option says to instead output literal UTF-8 characters.  If your *roff
	   implementation can handle it, this is the best output format to use and avoids
	   corruption of documents containing non-ASCII characters.  However, be warned that
	   *roff source with literal UTF-8 characters is not supported by many implementations
	   and may even result in segfaults and other bad behavior.

	   Be aware that, when using this option, the input encoding of your POD source must be
	   properly declared unless it is US-ASCII or Latin-1.	POD input without an "=encoding"
	   command will be assumed to be in Latin-1, and if it's actually in UTF-8, the output
	   will be double-encoded.  See perlpod(1) for more information on the "=encoding"

       -v, --verbose
	   Print out the name of each output file as it is being generated.

       If pod2man fails with errors, see Pod::Man and Pod::Simple for information about what
       those errors might mean.

	   pod2man program > program.1
	   pod2man SomeModule.pm /usr/perl/man/man3/SomeModule.3
	   pod2man --section=7 note.pod > note.7

       If you would like to print out a lot of man page continuously, you probably want to set
       the C and D registers to set contiguous page numbering and even/odd paging, at least on
       some versions of man(7).

	   troff -man -rC1 -rD1 perl.1 perldata.1 perlsyn.1 ...

       To get index entries on "STDERR", turn on the F register, as in:

	   troff -man -rF1 perl.1

       The indexing merely outputs messages via ".tm" for each major page, section, subsection,
       item, and any "X<>" directives.	See Pod::Man for more details.

       Lots of this documentation is duplicated from Pod::Man.

       For those not sure of the proper layout of a man page, here are some notes on writing a
       proper man page.

       The name of the program being documented is conventionally written in bold (using B<>)
       wherever it occurs, as are all program options.	Arguments should be written in italics
       (I<>).  Functions are traditionally written in italics; if you write a function as
       function(), Pod::Man will take care of this for you.  Literal code or commands should be
       in C<>.	References to other man pages should be in the form "manpage(section)", and
       Pod::Man will automatically format those appropriately.	As an exception, it's traditional
       not to use this form when referring to module documentation; use "L<Module::Name>"

       References to other programs or functions are normally in the form of man page references
       so that cross-referencing tools can provide the user with links and the like.  It's
       possible to overdo this, though, so be careful not to clutter your documentation with too
       much markup.

       The major headers should be set out using a "=head1" directive, and are historically
       written in the rather startling ALL UPPER CASE format, although this is not mandatory.
       Minor headers may be included using "=head2", and are typically in mixed case.

       The standard sections of a manual page are:

	   Mandatory section; should be a comma-separated list of programs or functions
	   documented by this POD page, such as:

	       foo, bar - programs to do something

	   Manual page indexers are often extremely picky about the format of this section, so
	   don't put anything in it except this line.  A single dash, and only a single dash,
	   should separate the list of programs or functions from the description.  Do not use
	   any markup such as C<> or B<>.  Functions should not be qualified with "()" or the
	   like.  The description should ideally fit on a single line, even if a man program
	   replaces the dash with a few tabs.

	   A short usage summary for programs and functions.  This section is mandatory for
	   section 3 pages.

	   Extended description and discussion of the program or functions, or the body of the
	   documentation for man pages that document something else.  If particularly long, it's
	   a good idea to break this up into subsections "=head2" directives like:

	       =head2 Normal Usage

	       =head2 Advanced Features

	       =head2 Writing Configuration Files

	   or whatever is appropriate for your documentation.

	   Detailed description of each of the command-line options taken by the program.  This
	   should be separate from the description for the use of things like Pod::Usage.  This
	   is normally presented as a list, with each option as a separate "=item".  The specific
	   option string should be enclosed in B<>.  Any values that the option takes should be
	   enclosed in I<>.  For example, the section for the option --section=manext would be
	   introduced with:

	       =item B<--section>=I<manext>

	   Synonymous options (like both the short and long forms) are separated by a comma and a
	   space on the same "=item" line, or optionally listed as their own item with a
	   reference to the canonical name.  For example, since --section can also be written as
	   -s, the above would be:

	       =item B<-s> I<manext>, B<--section>=I<manext>

	   (Writing the short option first is arguably easier to read, since the long option is
	   long enough to draw the eye to it anyway and the short option can otherwise get lost
	   in visual noise.)

	   What the program or function returns, if successful.  This section can be omitted for
	   programs whose precise exit codes aren't important, provided they return 0 on success
	   as is standard.  It should always be present for functions.

	   Exceptions, error return codes, exit statuses, and errno settings.  Typically used for
	   function documentation; program documentation uses DIAGNOSTICS instead.  The general
	   rule of thumb is that errors printed to "STDOUT" or "STDERR" and intended for the end
	   user are documented in DIAGNOSTICS while errors passed internal to the calling program
	   and intended for other programmers are documented in ERRORS.  When documenting a
	   function that sets errno, a full list of the possible errno values should be given

	   All possible messages the program can print out--and what they mean.  You may wish to
	   follow the same documentation style as the Perl documentation; see perldiag(1) for
	   more details (and look at the POD source as well).

	   If applicable, please include details on what the user should do to correct the error;
	   documenting an error as indicating "the input buffer is too small" without telling the
	   user how to increase the size of the input buffer (or at least telling them that it
	   isn't possible) aren't very useful.

	   Give some example uses of the program or function.  Don't skimp; users often find this
	   the most useful part of the documentation.  The examples are generally given as
	   verbatim paragraphs.

	   Don't just present an example without explaining what it does.  Adding a short
	   paragraph saying what the example will do can increase the value of the example

	   Environment variables that the program cares about, normally presented as a list using
	   "=over", "=item", and "=back".  For example:

	       =over 6

	       =item HOME

	       Used to determine the user's home directory.  F<.foorc> in this
	       directory is read for configuration details, if it exists.


	   Since environment variables are normally in all uppercase, no additional special
	   formatting is generally needed; they're glaring enough as it is.

	   All files used by the program or function, normally presented as a list, and what it
	   uses them for.  File names should be enclosed in F<>.  It's particularly important to
	   document files that will be potentially modified.

	   Things to take special care with, sometimes called WARNINGS.

	   Things that are broken or just don't work quite right.

	   Bugs you don't plan to fix.	:-)

	   Miscellaneous commentary.

	   Who wrote it (use AUTHORS for multiple people).  Including your current e-mail address
	   (or some e-mail address to which bug reports should be sent) so that users have a way
	   of contacting you is a good idea.  Remember that program documentation tends to roam
	   the wild for far longer than you expect and pick an e-mail address that's likely to
	   last if possible.

	   Programs derived from other sources sometimes have this, or you might keep a
	   modification log here.  If the log gets overly long or detailed, consider maintaining
	   it in a separate file, though.

	   For copyright

	       Copyright YEAR(s) by YOUR NAME(s)

	   (No, (C) is not needed.  No, "all rights reserved" is not needed.)

	   For licensing the easiest way is to use the same licensing as Perl itself:

	       This library is free software; you may redistribute it and/or modify
	       it under the same terms as Perl itself.

	   This makes it easy for people to use your module with Perl.	Note that this licensing
	   is neither an endorsement or a requirement, you are of course free to choose any

       SEE ALSO
	   Other man pages to check out, like man(1), man(7), makewhatis(8), or catman(8).
	   Normally a simple list of man pages separated by commas, or a paragraph giving the
	   name of a reference work.  Man page references, if they use the standard
	   "name(section)" form, don't have to be enclosed in L<> (although it's recommended),
	   but other things in this section probably should be when appropriate.

	   If the package has a mailing list, include a URL or subscription instructions here.

	   If the package has a web site, include a URL here.

       In addition, some systems use CONFORMING TO to note conformance to relevant standards and
       MT-LEVEL to note safeness for use in threaded programs or signal handlers.  These headings
       are primarily useful when documenting parts of a C library.  Documentation of object-
       oriented libraries or modules may use CONSTRUCTORS and METHODS sections for detailed
       documentation of the parts of the library and save the DESCRIPTION section for an
       overview; other large modules may use FUNCTIONS for similar reasons.  Some people use
       OVERVIEW to summarize the description if it's quite long.

       Section ordering varies, although NAME should always be the first section (you'll break
       some man page systems otherwise), and NAME, SYNOPSIS, DESCRIPTION, and OPTIONS generally
       always occur first and in that order if present.  In general, SEE ALSO, AUTHOR, and
       similar material should be left for last.  Some systems also move WARNINGS and NOTES to
       last.  The order given above should be reasonable for most purposes.

       Finally, as a general note, try not to use an excessive amount of markup.  As documented
       here and in Pod::Man, you can safely leave Perl variables, function names, man page
       references, and the like unadorned by markup and the POD translators will figure it out
       for you.  This makes it much easier to later edit the documentation.  Note that many
       existing translators (including this one currently) will do the wrong thing with e-mail
       addresses when wrapped in L<>, so don't do that.

       For additional information that may be more accurate for your specific system, see either
       man(5) or man(7) depending on your system manual section numbering conventions.

       Pod::Man, Pod::Simple, man(1), nroff(1), perlpod(1), podchecker(1), troff(1), man(7)

       The man page documenting the an macro set may be man(5) instead of man(7) on your system.
