 # Use CMake to generate the build files for your platform
 #
 # This script supports some configuration through CMake arguments (-Dparam=val syntax):
-#   BUILD_TOOLS=1          sets up additional executables to be built along with the server (ProtoProxy, GrownBiomeGenVisualiser, MCADefrag)
-#   BUILD_UNSTABLE_TOOLS=1 sets up yet more executables to be built, these can be broken and generally are obsolete (GeneratorPerformanceTest)
-#   CROSSCOMPILE=1         marks the build as a crosscompile (doesn't include optimizations for current platform)
-#   DISABLE_SYSTEM_LUA=1   disables the use of system Lua interpreter; the tolua executable will be built and used instead. Incompatible with cross-compiling
-#   SELF_TEST=1            enables testing code to be built
