Originally written by Stefan Jokisch in 1995-1997.
Ported to Unix by Galen Hazelwood.
Reference code and Unix port currently maintained by David Griffith.

- Compiles and runs on most common flavors of Unix, both open source and not.
- Plays all Z-code games including V6.
- Old-style sound support through OSS driver.
- Config files.
- Configurable error checking.
- Default use of the Quetzal file format. Command line option to use the
old format. There are several differences between the old-style save
format at Quetzal such that converting from old-style and Quetzal is
difficult if not impossible. This also means you can't restore an
old-style save and then save your game in Quetzal.
- Optional speech synthesis and recognition through FLITE and Sphinx.
