# This module is a bridge.
#
# Code is copied from Python 2.6 (trunk) Lib/test/test_support.py that
# the bsddb test suite needs even when run standalone on a python
# version that may not have all of these.
# DO NOT ADD NEW UNIQUE CODE. Copy code from the python trunk
# trunk test_support module into here. If you need a place for your
# own stuff specific to bsddb tests, make a bsddb.test.foo module.
