.Map :: MoHAA Mapping

In some AA shaders i see the line nextboundle (I think that's it, I'm at work and don't have the game files here to check). I can't find any reference to this in the Q3shader manual, what does it do? I tried to remove it and couldn't really see any difference.

It's a command introduced by Ritualistic and therefore not available in Quake 3. It allows you to use multiple textures in one stage using the same blendfunc.
