• Made <MATCH=...> work in the top-level pattern of a grammar

• Added l10n feature for <error:...> and <warning:...> directives (thanks Aki!)
• Added <minimize:> directive
• Fixed debugging directives in grammars
• Added per-hash key patterns to <%HASH> (Thanks Aki)

1.012 Wed Nov 3 20:24:36 2010

• Added RFC5322 example (thanks Tom and Abigail!)

• Added NEXT:: namespace for generic polymorphism

1.013 Wed Jun 29 14:39:40 2011

• Improved in-doc calculator example (thanks Jake!)
• Improved RFC5322 example (thanks Tom and Abigail)
