-# Project that runs the Clang regression tests for a given glob pattern.

-# There are several CMake cache variabes that must be set for this
-# project to work:
-#
-#   CLANG_TEST_RUNNER: The TestRunner.sh shell script, which is used to test
-#   Clang.
-#
-#   CLANG_TEST_GLOB_PATTERNS: Set to a GLOB pattern to identify the kind of
-#   tests, e.g., *.cpp for C++ tests.
-#
-#   LLVM_TOOLS_PATH: The directory where the Clang and LLVM tool
-#   executables (such as opt) are generated.
-#
-#   LLVM_SCRIPTS_PATH: The directory where the LLVM test scripts are
-#   located.
