From the webpage:
Python module which implements a template based state machine for parsing semi-formatted text. Originally developed to allow programmatic access to information returned from the command line interface (CLI) of networking devices.
TextFSM was developed internally at Google and released under the Apache 2.0 licence for the benefit of the wider community.
See: TextFSMHowto for details.
TextFSM looks like a useful Python module for extracting data from “semi-structured” text.
I first saw this in Nat Torkington’s Four short links: 29 August 2013.
