gzdoom/src/w_zip.h
Randy Heit 75b7db858f - Added support for zip/pk3 files with LZMA and bzip2 compression to ZDoom.
- Added more output to zipdir and a -q option to turn it off.
- Added -u option to zipdir to only recompress those files in a zip that have
  changed. 
- Added -d and -f options to zipdir. -d forces deflate compression, and -f
  forces a write of the zip, even if it's newer than all the files it contains.
- Added support for bzip2 and LZMA compression to zipdir.
