Yeah, I'd say more than half the repacks out there are strips from previously made repacks from AC-web, at least the programs are, BUT!, <-flamers notice the but! they add custom scripting into it as well as their own custom implements in-game thus providing us with something brand new to work with...
Repacks (IMO again) are packages with all the programs you need to run a server as well as a database, new repacks should include either the most recent programs (ascent, logonserver, etc) as well as new DB content (with fixed bugs)
