+version @url{https://luarocks.org/en/Dependencies, dependency} information.
+This information can be used both during installation, so that when one rock
+is requested all rocks it depends on are installed as well, and also
+optionally at run time, so that when a module is required, the correct version
+is loaded.  LuaRocks supports both local and
+@url{http://luarocks.org/en/Rocks_repositories, remote} repositories, and
+multiple local rocks trees.")
