• [fix] A bug fix

Does this PR introduce a BREAKING CHANGE?

Potentially.
Currently all the examples seem to end with "/" if it's an directory, so should work. If user creates an include "/path/to/an/directory", it will only create "/path/to/an/", as it doesn't have a way to determine it better, than the slash at the end.
