I thought I would package an actual release of the UNIX version, since it's very easy to do with autotools. If you don't want this version, check out the branches in this repo for versions in lisp, java, win32, etc.
Ignore the "Source Code" downloads that GitHub makes automatically, unless you want to run autoreconf and makeinfo yourself. The bascat-1.1.tar.gz file is the ready-to-configure source release.
