 This script is used to continually test libc++ and libc++abi trunk 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.
-  --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).
-  [--lit-args]      Additional arguments to pass to lit (optional). If there are multiple arguments, quote them to pass them as a single argument to this script.
-  [--no-cleanup]    Do not cleanup the temporary directory that was used for testing at the end. This can be useful to debug failures. Make sure to clean up manually after.
-  [-h, --help]      Print this help.

+  --libcxx-exceptions Whether to enable exceptions when building libc++ and running the libc++ tests. libc++abi is always built with support for exceptions because other libraries in the runtime depend on it (like libobjc). This must be ON or OFF.
