You must have bakefile installed if you want to regenerate the makefiles. Bakefile currently runs on Unix and Windows systems.

The makefile uses Unix make -syntax and works on Unix or using either Borland Make or GNU Make (including -native Win32 port called mingw32-make from http://www.mingw.org/) on Windows. -It is possible that other Windows make utilities work as well, but it wasn't -tested.
