NAME
    pod2usage - print usage messages from embedded pod docs in files

SYNOPSIS
    pod2usage   [-help] [-man] [-exit *exitval*] [-output *outfile*]
                [-verbose *level*] [-pathlist *dirlist*] *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).

    *file*  The pathname of a file containing pod documentation to be output
            in usage mesage 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
    specifed than standard input is read.

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