Testresources is licensed under two licenses, the Apache License, Version 2.0
or the 3-clause BSD License. You may use this project under either of these
licenses - choose the one that works best for you.

We require contributions to be licensed under both licenses. The primary
difference between them is that the Apache license takes care of potential
issues with Patents and other intellectual property concerns. This is
important to Testresources as Testresources wants to be license compatible in a
very broad manner to allow reuse and incorporation into other projects.

Generally every source file in Testresources needs a license grant under both
these licenses.  As the code is shipped as a single unit, a brief form is used:
----
Copyright (c) [yyyy][,yyyy]* [name or 'Testresources Contributors']

Licensed under either the Apache License, Version 2.0 or the BSD 3-clause
license at the users choice. A copy of both licenses are available in the
project source as Apache-2.0 and BSD. You may not use this file except in
compliance with one of these two licences.

Unless required by applicable law or agreed to in writing, software distributed
under these licenses is distributed on an "AS IS" BASIS, WITHOUT WARRANTIES OR
CONDITIONS OF ANY KIND, either express or implied.  See the license you chose
for the specific language governing permissions and limitations under that
license.
----

Code that has been incorporated into Testresources from other projects will
naturally be under its own license, and will retain that license.

A known list of such code is maintained here:
* The test_all.py and python/subunit/tests/TestUtil.py module are GPL test
  support modules. There are not installed by Testresources - they are only ever
  used on the build machine.  Copyright 2004 Canonical Limited.
