+This option defines the command to use with the B<--compile-custom>
+option to compile the bitcode testcase. This can be useful for
+testing compiler output without running any link or execute stages. To
+generate a reduced unit test, you may add CHECK directives to the
+testcase and pass the name of an executable compile-command script in this form:
+
+    #!/bin/sh
+    llc "$@"
+    not FileCheck [bugpoint input file].ll < bugpoint-test-program.s
+
+This script will "fail" as long as FileCheck passes. So the result
+will be the minimum bitcode that passes FileCheck.
