As for the engines, just 'ls' in the adva-cms2 repository, and you'll
get all of the currently available available engines.
That would include:
[chris@turnstile adva-cms2]$ ls | grep adva
adva-blog
adva-cache
adva-categories
adva-core
adva-markup
adva-static
adva-user
[chris@turnstile adva-cms2]$
Of course, there are also the engines that you develop yourself :)
