=head1 NAME

Pod::Parser::Groffmom::Entities - Internal entity conversions

=head1 VERSION

Version 0.042

=head1 DESCRIPTION

Most characters can be typed direclty into the POD documents you wish to
translate, but if you cannot type them, or if processing a document which
already has them, the following is our conversion list for named entities
entered into POD as C<EE<lt>entity_nameE<gt>>.

List gleefully stolen from C<HTML::Entities>.

=head1 Entities and their names

The following list shows the allowed entity conversions for C<< E<> >>
entities.  The list is not formatted terribly well since POD is rather limited
here.  Plus, CPAN has trouble with some of the formats I attempted.

The format is <I<entity> =E<gt> I<POD escape>>.
