Re: Who is using modified Lua versions, what are they and why?

Some time ago I've been developing an encryption and signing tool for
compiled Lua chunks.

It involved a few slight changes in luac and lua:
 - swapping calls to "require" with different call to a different function
with statically determined parameters during compile time
 - updating "lua_load()" (?, or some other loader related functions)
with signature checks and loading from encrypted binary blob

The project this tool was being developed for was a proprietary one and
killed in a few years,
also based on latest and greatest (back then) 5.1, so... I do not recall
much of the details.
Will check some old back-ups, it may be interesting to doodle around.

Kind regards
