I can't. That's exactly what I'm trying to avoid. Maybe some info about 
what I'm trying to do is needed.

I'm doing some web stuff based upon Xavante, CgiLua and Orbit. From 
Xavante, I stripped the Copas' based server and replaced it with a 
multithreaded one written in C. I have a pool of luaStates, so when 
serving a request, I pick a state and pass control to it. From that 
point on, it behaves like Xavante, parsing the request, picking the 
right handler, etc.

I need to move away from relative paths because I can have two scripts 
running at the same time, each of them in different physical 
directories. I had to tweak CGILua to avoid changing directories and 
running each script with a full path.

This is working fine, I just prepend cgilua.script_pdir to the file I 
want to run. My problem is with Orbit. It relies on the process' current 
directory being the one in which the "orbit-enabled" app is located.

I'd like to avoid PA's suggestion about using debug.getinfo, since I 
might need to remove it, to disallow scripts fiddling with it.
And I also would like to decrease the amount of 'path configuration' 
needed. I just want to say where a module is to be required, then I want 
the module itself to figure where are its resources.
