The problem often appears when wanting a program to be self-contained.
Then the best way is for the main module to update package.path
directly before requiring anything, but this requires that the module
knows exactly where it is loaded from; you can usually get this from
arg[0]. That is, say arg[0] is '/bonzo/dog/main.lua' then you can
prepend '/bonzo/dog/?.lua;' to the package.path.
