Gruntmaster::Page - Perl extension for blah blah blah

=head1 SYNOPSIS

  use Gruntmaster::Page;
  blah blah blah

unedited.

Blah blah blah.

=head2 EXPORT

None by default.

related modules or operating system documentation (such as man pages
in UNIX), or any relevant external documentation such as RFCs or
standards.

If you have a mailing list set up for your module, mention it here.
