Vala is object oriented language, similar to C#, though compilable to machine native code.
Vala-lemon-extractor extracts Flex/Lemon grammar definitions from metadata contained in vala source files. When you run vala-lemon-extractor from command line, it operates on *.vala files in current directory. If it finds a class that has at least one method marked with [Flex()] attribute, it produces Flex scanner for this class. There can be many such classes, and for each of them separate Flex scanner will be produced. If val
