-== Linux ==
+== Linux / Mac OS X ==
Build as:
export TRACE_LIBGL=/path/to/real/libGL.so.1
/path/to/application
+See the 'ld.so' man page for more information about LD_PRELOAD and
+LD_LIBRARY_PATH environment flags.
+
+
+== Mac OS X ==
+
+Usage on Mac OS X is similar to Linux above, except for the tracing procedure,
+which is instead:
+
+ DYLD_LIBRARY_PATH=/path/to/apitrace/wrappers /path/to/application
+
+Note that although Mac OS X has an LD_PRELOAD equivalent,
+DYLD_INSERT_LIBRARIES, it is mostly useless because it only works with
+DYLD_FORCE_FLAT_NAMESPACE=1 which breaks most applications. See the 'dyld' man
+page for more details about these environment flags.
+
