-        This Agent generates Events based on NextBus GPS transit predictions.  First, select an agency by visiting http://www.nextbus.com/predictor/agencySelector.jsp and finding your transit system.  Once you find it, copy the part of the URL after `?a=`.  For example, for the San Francisco MUNI system, you would end up on http://www.nextbus.com/predictor/stopSelector.jsp?a=sf-muni and copy "sf-muni".  Put that into this Agent's agency setting.

       The tags are listed as tag="1234". Copy that number and add the route before it, separated by a pipe '&#124;' symbol.  Once you have one or more tags from that page, add them to this Agent's stop list.  E.g,
