is the case for views.

Public scripts and stylesheets will be split into categories depending
of their use. This will be done in a hierarchical way according to the
views. custom.css object will be added, previxed of their domain of
operation.

Logs for updating comet scripts are not required, as they are mostly
straightforward functions and generally make a mess of logs.
