I have been coding this reinc simulator for a quite long time already, although it isn't yet as usable as I would like it to be. But people have been asking about the program, so here is the current code. Requires gtkmm 2.0, gtk+ 2.0 and gcc 2.95.x or 3.2.x. Developed and tested under FreeBSD 4.7 (stable), but should work with Linux too.
Note: If you don't have Qt 3.0.x and Qmake installed, use this Makefile.
