+Certain features can be enabled/disabled at compile time by passing
+additional arguments to Make in the form "NAME=VALUE", where NAME is
+one of those listed below and VALUE is typically 0 for disabled, 1 for
+enabled.
+
+ ENABLE_NLS=1
+
+ Enable native language support. May require additional
+ libraries.
+
+ ENABLE_TILT=wii
+
+ Enable Wii Remote support. Requires additional libraries and
+ system configuration.
+
+ ENABLE_TILT=loop
+
+ Enable Hillcrest Labs Loop support. Requires additional
+ libraries and system configuration.
+
+ ENABLE_FS=stdio
+
+ Enable alternate file system backend that uses standard I/O
+ instead of PhysicsFS (thus making the dependency optional),
+ but does not provide archive support.
+
+Under Mac OS X, build using the provided Xcode project files.
+
+For Windows builds, the MinGW cross-compilation environment is
+supported. (Native builds are theoretically possible using MinGW and
+MSYS. Although care is taken to preserve compatibility with MSYS, no
+support exists and no actual testing is done.)
