=head1 NAME

Socialtext::Formatter::Wafl - Wiki Abstract Formatting Language

=head1 DESCRIPTION

Wafl is a flexible way of adding additional formatting functionality,
often dynamic, to a wikitext syntax. It comes in two forms
L<Socialtext::Formatter::WaflBlock> and L<Socialtext::Formatter::WaflPhrase>.

=over 4

=item escape_wafl_dashes 

For Wikiwyg, we need to turn HTML comments within wikihints
into something else. Otherwise dom parsing gets in trouble.
