What does ACM stand for?

Question

I see that phpBB uses the term often to describe things like XCache, ACP, eAccelerator: http://wiki.phpbb.com/display/DEV/Cache, but what does ACM actually stand for?

I understand that all of these are PHP caching mechanisms and I use XCache myself, but I could not find what "ACM" actually translates to.

Answer 1

According to this document it is their custom structure for controlling cache. If it has a translation, it is probably something local to the phpBB developers.

Answer 2

I'm not a phpBB expert, but from a quick search I would guess it means Advanced Cache Manager.
