LuaRocks does not impose its structure to apps necessarily; when a
module is not found in the LuaRocks tree it falls back to standard
require(), so modules are searched for in the user's

Do you mean moving modules away from the rocks tree? This might
confuse the system. If the plan is to ship both LuaRocks and non-rocks
modules, my suggestion would be to have a usual flat lib directory
with non-rocks modules, and to ship a rocks tree populated with stub
entries for modules that are already there as non-rocks (so that, for
example, when a user types 'luarocks install shake' it does not
download LuaFileSystem again, assuming it would be one of your
