plugin compiler

After I have looked at many lexer and parser generators for python, I 
came to the conclusion that it is best to write the lexer and parser by 
hand.

Reason: All generators I found lacked one important feature. They could 
not generate a standalone parser, i.e. a python script that can be 
executed on every box that has python installed.

Each generator requires a special library to be installed. Since 
everyone who wants to compile GePhex will need the parser, this would be 
a significant annoyance for many people.

My current plan is to write a lexer and a parser for our simple spec 
language by hand and in pyhton.

Probably the spec compiler will output some idl and an idl compiler will 
produce the code.

Any objections?
