# We need to execute checker.py rather than simply importing it. However,
# since pychecker is not a private package, we don't know exactly where it will
# be located. So, we run a little Python script first to find the correct
# location, and then execute it from there.
#
# Expect CHECKER_PATH to be something like:
#
# /var/lib/python-support/pythonX.Y/pychecker/checker.py
#
# Its actual location will depend on how update-python-modules is implemented.
#
# This script also supports the use of $PYTHONVER as a way to select which
# version of Python will be used to execute pychecker. This will only work for
# versions of Python supported by python-support, but it's better than nothing.
