Expect (was: Software Defined Networks)

I (and another programmer, now at Amazon) migrated our automation from 
TCL/Expect to Python/pexpect.  I've had to write code for those portions 
of Expect that didn't carry over into pexpect.

I also had to build a framework that allowed me to do rule-based 
programming in the same flavor as Expect's "expect" statement, which 
isn't hard but tedious as all get-out.  Maintenance of the code using 
the framework is head and shoulders better than the same tasks in 
Expect.  Particularly when Cisco makes little changes in their 
operations as you move up the revision chain.
