Roadrunner

Roadrunner is a Brainfuck clone language created by Connor Scialdone. It is based off of the popular Looney Tunes character Roadrunner, who, as is fairly well known, pretty much only ever says 'Meep meep!'.

The language currently only has one implementation in the form of a Python interpreter; The interpreter in question can also be easily modified to produce a Brainfuck clone with any syntax (to a certain extent). It includes a compiler from Brainfuck to the clone language as well.

Commands
Each command in Roadrunner is the word 'meep' with different capitalization, separated by spaces. Any unrecognized tokens will be ignored - however, be careful not to use 'meep' in any comments.

Computational class
Roadrunner is a direct syntax swap of Brainfuck, therefore it is Turing-complete.
