Hi @tyleragreen ,
Thank you so much for providing this repository. I'll use it now to build databases from GTFS from public transport agencies. I have not found any license information in this repository. Do you mind adding a license? Personally, open source can not be ranked highest. If you ask me, I suggest licenses like GNU GPL or GNU FDL. This is a good list of open source licenses with comparison.

Cheers!
