If you want to port your wikis too, this will also work, although it's only a 90% solution for wikis. Github and gitlab use different file name and markdown conventions.

Note that the gitlab repo must exist for the script to work. The gitlab wiki repo doesn't need to exist though, that will get created if the original github repo had a wiki.
