kstart 2.2

I've released a new version of the kstart and k5start package. I went over all of the code for both with a scrub brush and also got rid of a lot of Stanford-specific banners and environment variable checks. The code should be easier to read and more maintainable now.

I also substantially overhauled the man pages, improved the other documentation, improved the build system, switched to Autoconf 2.5x, and added Debian rules.

Debian packages are also available but I haven't gotten around to announcing my Debian archive yet. I'll do that probably tomorrow after I finish cleaning up and releasing apt-index (although I may instead work on teaching apt-ftparchive how to generate Release files as part of the generate step, since apparently that should be easy).

Anyway, you can get the latest versions from the kstart distribution page.
