binary with the ast file as input (`./IMP < Imp.ast`). This will print out text
representing a valid input for the Happy parser generator.
To compile, simply run happy, then ghc over the parser generator generator:
`happy AST.y; ghc AST.hs` (stack coming soon).
Stack is used to manage packages etc. but I can't figure out how to integrate
happy and alex into stack/cabal, so there is a simple Makefile which runs happy
and alex and then hands the rest of the work to stack.
Setup and build with `stack setup`, `make`. The executable is gg-proto,
which takes the .ast file either from the command line or stdin, run with
`stack exec gg-proto file`.
`AST.y` is the grammar for the mini-language for parsing the user's AST declaration.
It reads all the grammar directives, and assembles them into a grammar that represents
