Good Q2 utils with source available to use as a base?

[jitspoe]

I want to fix a few issues I've seen with Q2 compilers, but I'm not sure what a good starting point is. I really want something like arghrad that I could make a few modifications to, but I don't think Argh! plans to release the source, even if I could manage to get in touch with him. I'm looking at Geoffrey DeWan's stuff now, as it has some tweaks and fixes. Is there something better that I should be looking at? I looked at q2wmap as well, but it has completely removed radiosity, which I want to keep.

Alien Arena q3rad? I have no idea if it works with stock q2.

Is alien arena using the Q3 BSP format?

For the time being, I need to use the Q2 format.

last I checked, it was q2bsp, but that was a long time ago.
/me gets curious.
/me hunts for code.
#define BSPVERSION 38
interesting.
its q2 format still.

however, it looks like they have some glorified .lit alternative which would need engine support. the comments in their qfiles.h file imply that the extra parts are a function of the values stored in the bsp itself which would mean that it could only be used to double lightmap resolution or something, so presumably you'd get still something usable even without that, I don't know if their light tool still writes the vanilla lighting data.
