PyFSA

A python CLI to render finite state graphs.

This application takes a CSV file with state information, and uses it to either produce the finite state graph, and verify that strings are valid given the state information, a start state, and a desired state. The string subcommand is also able to render the traversal graph of a string through the state machine.
