I have prepared a new package of upstream SVN snapshot r262 that
replaces the non-free MAME OPL2 emulator with a GPL'ed one from
DOSBOX. Furthermore, I got a confirmation email by John Carmack
himself of iD software stating that the original Wolf3d source code
has been relicensed under the GPL. Thus, the whole package is under
GPL now!
I am still looking for a sponsor/co-maintainer. Please find the
package here
