Recommendations for writing a user guide with examples?

[Neal Becker]

I'm looking for recommendations for writing a user manual.  It will need
lots of examples of command line inputs and terminal outputs.

I'd like to minimize the effort to integrate the terminal input/output into
my document.  I have lots of experience with latex, but I wonder if there
may be some other choices.  Maybe docutils, pydoc, something else?  The
code I'm documenting is written in python, if that matters.
