Unfortunately if you are using the Final Release of Rb (v1.0) then you will need to waypoint all new maps manually. Also, I think that .pwf files are for podbot (and therefore won't work with Realbot).

If you're ok with setting up Metamod, then I would suggest that you download and install the latest Realbot WIP (work in progress), build 2079 (or WIP #7). This enables the bots to learn the map automatically, by watching human players. All you need to do is run around the maps, and after a few rounds the bots will use those routes (very basically put, as I think it's even more intelligent than that).

Stefan's download page has all the links you need for the latest WIP, as well as the 'RB-friendly' version of metamod.dll

To use the latest WIP, you have to setup Realbot to work with metamod (which is easy).
