=head1 NAME

Gruntmaster::Page - Perl extension for blah blah blah

=head1 SYNOPSIS

  use Gruntmaster::Page;
  blah blah blah

=head1 DESCRIPTION

Stub documentation for Gruntmaster::Page, created by h2xs. It looks like the
author of the extension was negligent enough to leave the stub
unedited.

Blah blah blah.

=head2 EXPORT

None by default.


=head1 SEE ALSO

Mention other useful documentation such as the documentation of
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.

If you have a web site set up for your module, mention it here.
