"""A script that checks for unintended imports of twisted.internet.reactor."""

# NOTE: the goal of this script is to avoid a bug that affects
32
# ubuntuone-control-panel on windows and darwin. Those platforms use
33
# the qt4reactor, and will break if the default reactor is installed
34
# first. This can happen if a module used by control-panel (such as
35
# ubuntuone.platform.credentials), imports reactor. Only sub-modules
36
# that are not used by ubuntuone-control-panel can safely import
37
# reactor at module-level.
