NAME ^

Jifty::View::Declare::CoreTemplates - Templates Jifty can't function without

DESCRIPTION ^

This library contains templates that Jifty can't function without:

PubSub
Validate
Autocomplete
Canonicalize
YAML and XML webservice endpoints for core jifty functionality

These templates are still in masonland. we're doign something wrong with escaping in them
