=head1 NAME

PDF::API3::Compat::API2::Basic::TTF::Prep - Preparation hinting program. Called when ppem changes

=head1 DESCRIPTION

This is a minimal class adding nothing beyond a table, but is a repository
for prep type information for those processes brave enough to address hinting.

=head2 $t->read

Reads the data using C<read_dat>.
