# THIS SCRIPT DOESN'T DO ANYTHING YET!
#
# Some things this script could/should do when finished
#
# * detect the compiler name (g++/c++/...)
# * detect whether its a GNU compiler or not (for compiler settings)
# * detect the host platform and base settings on this:
#   - #defines like -DUNIX and -DMACOSX
#   - required libs like -lmingw32
# * command line options to...
#   - override the host settings (for cross compiles
#   - select the desired backend (sdl, x11, ...)
#   - whether to do a debug build (with -g) or an optimized build (-O3 etc.)
# * detect whether the chosen backend is available (e.g. call sdl-config)
# * generate a config.mak file for use in makefiles
# * ....
