 =head1 SYNOPSIS
 
 This module will parse L<WebPAC::Normalize/lookup> directives and generate source
-to produce lookups and normalization.
+to produce lookups and normalization. It will also parse other parts of
+source to produce some of DWIM (I<Do What I Mean>) magic
+(like producing MARC oputput using L<WebPAC::Output::MARC> if there are C<marc_*>
+rules in normalisation).
 
 It's written using L<PPI>, pure-perl parser for perl and heavily influenced by
 reading about LISP. It might be a bit over-the board, but at least it removed
