Our Copyright Policy

====================

IPython uses a shared copyright model. Each contributor maintains copyright

over their contributions to IPython. But, it is important to note that these

contributions are typically only changes to the repositories. Thus, the

IPython source code, in its entirety is not the copyright of any single person

or institution. Instead, it is the collective copyright of the entire IPython

Development Team. If individual contributors want to maintain a record of what

changes/contributions they have specific copyright on, they should indicate

their copyright in the commit message of the change, when they commit the

change to one of the IPython repositories.

Miscellaneous

=============

Some files (DPyGetOpt.py, for example) may be licensed under different

conditions. Ultimately each file indicates clearly the conditions under which

its author/authors have decided to publish the code.

Versions of IPython up to and including 0.6.3 were released under the GNU

Lesser General Public License (LGPL), available at

http://www.gnu.org/copyleft/lesser.html.
