a library knowing its whereabouts?

[Asko Kauppi <asko.kauppi@...>]

With the new library/package system, is it possible for a library 
module to know, where it is?
I'm changing Hamster to load by '-l hamster' and it would be awfully 
nice if the hamster.lua code could refer to other files, using its own 
installation path as a prefix.
I know.. you'll be saying use CPATH blahblah.. sure.  Only, if my 
Makefile says '-l Tools/Hamster/hamster' then what?  Also to avoid 
potential name clashes of subscript files, it would be better to look 
straight in the right dir, imho.
