+
+=over 8
+
+=item B<-help>
+
+Print a brief help message and exit.
+
+=item B<-man>
+
+Print this command's manual page and exit.
+
+=item B<-exit> I<exitval>
+
+The exit status value to return.
+
+=item B<-output> I<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.
+
+=item B<-verbose> I<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)
+
+=item B<-pathlist> I<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).
+
+=item I<file>
+
+The pathname of a file containing pod documentation to be output in
+usage mesage format (defaults to standard input).
+
+=back
+
+=head1 DESCRIPTION
+
+B<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.
+
+B<pod2usage> invokes the B<pod2usage()> function in the B<Pod::Usage>
+module. Please see L<Pod::Usage/pod2usage()>.
