Hi,
The Package Compatibility (Compat-5.1) is a set of files which provides an
implementation of the new package model of Lua 5.1 to be used in Lua 5.0.
Compat-5.1 release 3 follows Lua 5.1 work 6 implementation.
The implementation differences could be summarized in:
* Tables package and package.loaded are linked to functions require()
and module() so that there is no way to change these tables per se, only its
fields.
* Function require() uses a list of loaders which are functions
responsible for trying to load a module. Table package.loaders store these
functions.
Compat-5.1 is free software and uses the same license as Lua 5.0.
For more information on Compat-5.1 please check

Any feedback is welcome!

Compat-5.1 continues to be incompatable with Windows (and Mac?)!
I submitted a patch to someone, but maybe it went to the wrong place....
Here it is.... (perhaps primative - I'm not a Lua expert!):
