pod2usage

POD2USAGE(1)						 Perl Programmers Reference Guide					      POD2USAGE(1)

NAME

       pod2usage - print usage messages from embedded pod docs in files

SYNOPSIS

       pod2usage   [-help] [-man] [-exitexitval] [-outputoutfile] [-verbose level] [-pathlist dirlist] [-formatter module] [-utf8] file

OPTIONS AND ARGUMENTS

       -help   Print a brief help message and exit.

       -man    Print this command's manual page and exit.

       -exit exitval
	       The exit status value to return.

       -output outfile
	       The output file to print to. If the special names "-" or ">&1" or ">&STDOUT" are used then standard output is used. If ">&2" or
	       ">&STDERR" is used then standard error is used.

       -verbose level
	       The desired level of verbosity to use:

		   1 : print SYNOPSIS only
		   2 : print SYNOPSIS sections and any OPTIONS/ARGUMENTS sections
		   3 : print the entire manpage (similar to running pod2text)

       -pathlist dirlist
	       Specifies one or more directories to search for the input file if it was not supplied with an absolute path. Each directory path in
	       the given list should be separated by a ':' on Unix (';' on MSWin32 and DOS).

       -formatter module
	       Which text formatter to use. Default is Pod::Text, or for very old Perl versions Pod::PlainText. An alternative would be e.g.
	       Pod::Text::Termcap.

       -utf8   This option assumes that the formatter (see above) understands the option "utf8". It turns on generation of utf8 output.

       file    The pathname of a file containing pod documentation to be output in usage message format (defaults to standard input).

DESCRIPTION

       pod2usage will read the given input file looking for pod documentation and will print the corresponding usage message.  If no input file is
       specified then standard input is read.

       pod2usage invokes the pod2usage() function in the Pod::Usage module. Please see "pod2usage()" in Pod::Usage.

SEE ALSO

       Pod::Usage, pod2text(1)
