Nowadays, that should read "if you allow it to load its own package
loader", which is a more elegant thing to do.

Yes, by default it will assume you just want to load the latest
version of each module, but if a user has the concerns John has about
versioning and don't mind paying the price of an extra check during
require(), one can load luarocks.loader (`lua -lluarocks.loader
script.lua`, for example) and let LuaRocks sort it out. The loader
will use the dependency information specified in the rockspec (cached
in the manifest file).
