 This folder contains the scripts necessary to compile the decompiler into un.rpyc, a file which will

 .rpyc files are gzip compressed pickle files. Using the pickleast module we can exploit this by
 creating a pickle which will run the decompiler when ren'py is loading all files, before any .rpy
 code normally even runs.
