>From the file comments:

"""
Some features of lxc - networking and LSM configuration for instance -
are generally configured by the distro packages.  This program
tests the Ubuntu configuration.

These require the ubuntu lxc package to be installed.

General lxc functionality testing does not belong here.
"""

changelog v2:
  Switch to lxc-info -i to detect ip address as stgraber suggested
  Don't look for 'expect' as I'm not using it yet.
