What are ABS scripts?

[zzzdude]

I am relatively new to RPG maker XP, 2 months, so I have the just of understanding everything, except scripting.

I see everywhere "NEW IMPROVED ABS SCRIPT!"
But in the topic, (not necessarily on this forum) they don't explain what it is.

So, I was wondering what an ABS script is, and are there any other acronym named scripts I should be aware of?

I saw a CMS script, no idea what that was either.

So, anyone want to explain that to me?

ABS - Action Battle System
CMS - Custom Menu System, Custom Message System
