=head1 Name

remoos - Rewrite Moos.pm into Your Own Module

=head1 Synopsis

    remoos My::Base::Class > lib/My/Base/Class.pm

=head1 Description

L<Moos> is a L<Moose>-esque Perl OO framework that lives in one single file.
That makes it easy to turn it into your Perl module distribution's own OO base
class. This L<remoos> utility makes it easier.

The C<remoos> utility simply reads in a copy of Moos.pm, changes all the
references of I<Moos> to your module's name, and writes the result to stdout.

It will also remove comments and documentation, and add a comment at the top
indicating that it was derived from L<Moos>.
