lxml is copyright Infrae and distributed under the BSD license (see

doc/licenses/BSD.txt), with the following exceptions:



Some code, such a selftest.py, selftest2.py and

src/lxml/_elementpath.py are derived from ElementTree and

cElementTree. See doc/licenses/elementtree.txt for the license text.



lxml.cssselect and lxml.html are copyright Ian Bicking and distributed

under the BSD license (see doc/licenses/BSD.txt).



test.py, the test-runner script, is GPL and copyright Shuttleworth

Foundation. See doc/licenses/GPL.txt. It is believed the unchanged

inclusion of test.py to run the unit test suite falls under the

"aggregation" clause of the GPL and thus does not affect the license

of the rest of the package.
