I made a super-awesome UNNECESSARY interpreter in scratch. UNNECESSARY is the name of a programming language for those of you who haven't figured it out. You can run $ ls to get the contents of the directory. Then run $ ./unn [filename.unn] to interpret a unn file (that's a unnecessary program.) Have fun!
Can't figure this out? See http://esolangs.org/wiki/Unnecessary But TRY THE PROJECT A BIT FIRST!
