Garry's Mod 13 Map Cycle

I have a TTT server, but no map voting. This is because the old map voting was through Fretta, and there is no fretta anymore. So, I need some map voting. Anyone know of anyway to accomplish this? It doesn’t have to be the same way as fretta, but I need some kind of voting.

only one I have seen so far is a rock the vote script

Thanks for showing me that. I’m hoping someone knows of an actual end round voting script.
