The intermediate file format is not proprietary. It's just that if I
published it, I'd have to support it. I change it with nearly every new
version of the compiler, and don't want to worry about backwards
compatibility.

The format is basically symbol table records, expression trees in prefix
form, and a flow graph to connect the expressions together.
