I guess I can, sort of. Some people (like me) have not been in active "development" for the last 10 years or so.

I for one, never even liked the autoconf stuff (just a good Makefile) and have never actually used a version control system, so if I were to continue developing some of my old stuff I would just continue using emacs and a Makefile.

Maybe someday I could start using git and put some of my old projects (e.g. lepton's crack so I can learn how that all works!
