Makefile

#######################################################################
#
# Instructions:
#
# make
#   Compiles all .c and .cpp files in the src directory to .o
#   files in the obj directory, and links them into an
#   executable named 'game' or 'game.exe' in the currect directory.
#
# make clean
#   Removes all .o files from the obj directory.
#
# make veryclean
#   Removes all .o files and the game executable.
#
# Optional parameters:
#
# STATICLINK=1
#   Compiles/removes a statically linked version of the game without
#   DLL dependencies. The static object files are put in obj/static
#   and the executable has '_static' appended to the name.
#
# NAME=game_name
#   Sets the name of the game executable. By default the game
#   executable is called 'game' or 'game.exe'.
#
# If you use add-on libraries, add them to the lines starting with
# 'LIBS='. Make sure you enter the libraries in both lines, for the
# normal and static version!
