Very simple guide to using this script:

* Get csv2trainschedpdb from http://trainsched.sourceforge.net/ .

* Install transitfeed python module from
  https://code.google.com/p/googletransitdatafeed/wiki/TransitFeed .

* Grab the GTFS feed from the MTA.  At last check the feed was at
  http://mta.maryland.gov/_googletransit/latest/google_transit.zip , linked
  from http://mta.maryland.gov/about/publicgtfsdata.cfm .

* Decide what route(s) you want to generate databases for.  You can run
  `gtfs2csv.py --list-routes google_transit.zip` to see a list of available
  routes.  The part before the colon is what you need to select the route.
  Note that not all of the routes are obvious; the Light Rail's code is "[L]",
  for instance.

* Run gtfs2csv.py to generate the CSV file.  e.g.:
  $ gtfs2csv.py google_transit.zip 77 77-bus.csv

* Check the resulting CSV file to see if you like the stop ordering.  If you
  don't, you can override the standard ordering with the --stop-order option.
  Use the --list-stops option to get a list of stop IDs and then specify the
  ordering you want.  This can also be used if you don't want all of a route's
  stops in the database.

* Run csv2trainschedpdb on the CSV file.
  $ csv2trainschedpdb 77-bus.csv 77-bus.pdb 'Bus: 77'

* Sync the resulting PDB to your Palm.
