`appengine_config.py` is another story and whoever is going to change these things should know what they are doing.. but either case if you change the name to something else in the join it won't work.. so it has to be the same name.. I would prefer the other one.. otherwise in the `make_lib_zip` it has to be updated as well.. 

p.s. reverts could be directly discussed on the same commit diff in the future..
