+Usage on Mac OS X is similar to Linux above, except for the tracing procedure,

+  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.
