-When **lit** loads a subdirectory in a test suite, it instantiates a local test
-configuration by cloning the configuration for the parent direction --- the root
-of this configuration chain will always be a test suite. Once the test
-configuration is cloned **lit** checks for a *lit.local.cfg* file in the
-subdirectory. If present, this file will be loaded and can be used to specialize
-the configuration for each individual directory. This facility can be used to
-define subdirectories of optional tests, or to change other configuration
-parameters --- for example, to change the test format, or the suffixes which
-identify test files.
