A main motivation of this utility is to provide a platform-independent, easily deployable, and simple patch utility for LuaRocks .
To patch current directory using patch file "mypatch":

This code is new should undergo further testing. Some of the style might be further improved as it was converted from Python.
Note: Those code in the direct port is fairly ugly. It is being largely rewritten. If you want it sooner, just ask.
