How to set up lime?

Lime
#1

With some help I received info that when I get this error failing to compile a project for neko

Uncaught exception - std@sys_create_dir
Build halted with errors.

Is because cannot create a lime folder. If I set environment variable LIME_CONFIG = (custom\directory\.lime) or …(custom\directory\.lime\config.xml) compile error says “invalid xml data” of course if there is empty XML or no XML file in there, so what should be there for it to target correctly?

I use Flash Develop 5.3.4 and I dont recall having to set up lime like that to be able to compile projects.
