=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
The exit status value to return.
=item B<-output> I
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
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
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 B<-formatter> I
Which text formatter to use. Default is L, or for very old
Perl versions L. An alternative would be e.g.
L.
=item I
The pathname of a file containing pod documentation to be output in
usage message format (defaults to standard input).

=head1 DESCRIPTION
