I mentioned ZDBSP when I wrote about glBSP. It's my hope to remove glBSP from the archive, leaving ZDBSP as the sole Doom nodebuilder in Debian. I might try to do this in time for the next stable release. That means probably actioning the removal before the 12th March.
If you use glBSP for any purpose, please give ZDBSP a look and make sure it works for you.
