MINI Scheme Interperter

This is a Mini scheme Interpreter made with Haskell (Alex as lexical analyser, Happy as parser).
[!] This is not a perfect language or interpreter. I just made this as term project of univ lecture.
[!] I'm stilling working on this project. So, this might be a not final version.
