-\fBOIL_CPU_FLAGS\fR
-Useful liboil environment variable. Set OIL_CPU_FLAGS=0 when valgrind or
-other debugging tools trip over liboil's CPU detection (quite a few important
-GStreamer plugins like videotestsrc, audioconvert or audioresample use liboil).
+\fBORC_CODE\fR
+Useful Orc environment variable. Set ORC_CODE=debug to enable debuggers
+such as gdb to create useful backtraces from Orc-generated code. Set
+ORC_CODE=backup or ORC_CODE=emulate if you suspect Orc's SIMD code
+generator is producing incorrect code. (Quite a few important
+GStreamer plugins like videotestsrc, audioconvert or audioresample use Orc).
