 This script is used to continually test the back-deployment use case of libc++ and libc++abi on MacOS.
 
-  --libcxx-root       Full path to the root of the libc++ repository to test.
-  --libcxxabi-root    Full path to the root of the libc++abi repository to test.
+  --monorepo-root     Full path to the root of the LLVM monorepo. Both libc++ and libc++abi headers from the monorepo are used.
   --std               Version of the C++ Standard to run the tests under (c++03, c++11, etc..).
   --arch              Architecture to build the tests for (32, 64).
   --deployment-target The deployment target to run the tests for. This should be a version number of MacOS (e.g. 10.12). All MacOS versions until and including 10.9 are supported.
