 #     * Give the Sound flag if the application should be able to generate sounds.
 #   Systems:
 #     * Give the Linux flag when compiling on Linux or similar Posix systems having the same dependencies installed.
+#     * Give the MacOS flag when compiling on MacOS.
 #     * Give the Windows flag when compiling on Microsoft Windows.
-#   Features:
-#     * Give the ReuseMemory flag to enable memory recycling using allocator.cpp.
-#       This can cause crashes if you have more than one memory recycler linked,
-#       because you don't want one implementation allocating and another freeing.
-#   Strings use a subset of the C standard for mangling, so \\ is used to write \.
-#     You can also use / and let the file abstraction layer convert it into \ automatically when running on Windows.
