4 different compilers (gcc, gcc-arm-thumb, cl, csc)
3 different languages (C++, MC++, C#)
3 different platforms (x86, arm-thumb, msil)
5 different major compile targets (the game, the common library, the imager, the managed common library, the resource builder)
And takes approximately ten seconds to compile from clean, with about 2000 lines of code total. Booyeah!
Oh, and links to about 3mb of external libraries.
I, uh, still have a lot of code to write. But still.
