ruby-actionpack-2.3 2.3.14-2 (amd64 binary) in ubuntu quantal

 Action Pack splits the response to a requests into a controller part
 (performing the logic) and a view part (rendering a template). This
 two-step approach is known as an action, which will normally create,
 read, update, or delete (CRUD for short) some sort of model part
 (often backed by a database) before choosing either to render a
 template or redirecting to another action.
 .
 It eases web-request routing, handling, and response as a half-way
 front, half-way page controller. Implemented with specific emphasis
 on enabling easy unit/integration testing that doesn't require
 a browser.
