35 /// This frontend action is responsible for parsing model files. Model files can
36 /// not be parsed on their own, they rely on type information that is available
37 /// in another translation unit. The parsing of model files is done by a
38 /// separate compiler instance that reuses the ASTContext and othen information
39 /// from the main translation unit that is being compiled. After a model file is
40 /// parsed, the function definitions will be collected into a StringMap.
