# This is a hack to fix path problems because "borg" (the package) is in the source root.
# When importing the conftest an "import borg" can incorrectly import the borg from the
# source root instead of the one installed in the environment.
# The workaround is to remove entries pointing there from the path and check whether "borg"
# is still importable. If it is not, then it has not been installed in the environment
# and the entries are put back.
