You guys asked for one that worked... It took me a little while to tweak, esp. since I'm not a guru with python. The comment about needing mod_wsgi isn't true, unless you want to run lemur as a cgi program... I suspect that's from an older version that ran as cgi and not as a standalone webserver.
Mostly typos, grammar errors and inconsistent indentation in code
examples.
Some errors detected using Topy (https://github.com/intgr/topy), all
changes verified by hand.
supervisord should run as root and spawn the lemur process as the lemur
user. I also added the LEMUR_CONF environment variable because it was
not reading the configuration file in by default.
