This script only takes one option, C<--name>, which is required; it is
the name of the plugin to create; this will be prefixed with
C<Jifty::Plugin::> automatically.  Jifty will create a directory with
that name, and place all of the files it creates inside that
directory.

=item B<--help>

Print a brief help message and exits.

=item B<--man>

Prints the manual page and exits.
