NetworkWrangler is a python library that enables users to define roadway and transit projects as collection of data files in a local git repository, and then create networks by starting with a base network and applying a set of projects to that base network.
The base network and resulting network are in the Citilabs Cube format (http://www.citilabs.com/software/cube/)
NetworkWrangler is the brainchild of Billy Charlton, who was the Deputy Director for Technology Services at SFCTA through 2011. Contributors include:

Build a network by running the build_network.py script in the /scripts folder.
python build_network.py [-c configword] [-m test] network_specification.py
This will build a network using the specifications in network_specification.py, which should define the variables listed below (in this script)
If test mode is specified (with -m test), then the following happen:
- networks are built in OUT_DIR\TEST_hwy and OUT_DIR\TEST_trn
- RTP projects are not applied
- TAG is not used for TEST_PROJECTS
The [-c configword] is if you want an optional word for your network_specification.py (e.g. to have multiple scenarios in one file). Access it via CONFIG_WORD.
