==> Caveats
Please be aware due to the way Luarocks is designed any binaries installed
via Luarocks-5.3 AND 5.1 will overwrite each other in /usr/local/bin.

This is, for now, unavoidable. If this is troublesome for you, you can build
rocks with the `--tree=` command to a special, non-conflicting location and
then add that to your `$PATH`.
