-- Just like in Awesome, if you want access to Luarocks packages, this needs to be called.
-- NOTE: The loader doesn't load from the local Luarocks directory (probably in ~/.luarocks),
-- |     so if you have any rocks installed with --local,
-- |     you may need to add those paths to package.path and package.cpath.
-- Alternatively, you can add
--     eval $(luarocks path --bin)
-- to your shell's startup script to permanently have access to Luarocks in all your Lua files.
