pod2usage
POD2USAGE(1) User Contributed Perl Documentation POD2USAGE(1) NAME
pod2usage - print usage messages from embedded pod docs in files SYNOPSIS
pod2usage [-help] [-man] [-exit exitval] [-output outfile] [-verbose level] [-pathlist dirlist] [-formatter module] 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. 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
