This is just a small program forked from https://github.com/selkhateeb/h...

...ardlink which

creates hardlinks between folders which are otherwise not possible. The name of the
formula doesn't match the binary (hln vs hardlink-osx) because the name hardlink was taken!

The code if very straightforward and commented well. I believe this formula should have the
name "hardlink" because it is more accurate than the current one.
