NAME
Jifty::View::Declare::CoreTemplates - Templates Jifty can't function withoutDESCRIPTION
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
