# This script helps to test external gems in the content of the current
# Chef install. We want to make sure that the external gems will still function
# once we release Chef so we run *their* specs against the current contents
# of the chef / ohai repos. It let's us know if we need to update downstream
# gems or fix regressions in chef *before* we release.
