It's just an old addon I made for Garrysmod as a teen. Due to legal reasons (crappy work contracts) I haven't been able to put it on github until recently.
Better late than never!
Feel free to create pull requests and such! Any contribution is welcome.
Just file an issue here on GitHub
It's currently uploaded to the steam workshop here.
Q: Am I allowed to make my own release for my steam account? A: Yes but it would be appriciated if good changes can propagate through here.
