To debug the grammar
Alex 3.0 now supports unicode natively, and has been included as a dependency in the cabal file.
Note: The generation of the lexical analyser has been separated out, to remove the install-time dependency on Alex. If any changes need to be made to the lexer, the Lexer.x source lies in src-dev, and the runalex.sh script will invoke Alex with the appropriate directories.
