quote from http://www.oss-watch.ac.uk/resources/gpl.xml#body.1_div.4
It is also commonly believed that GPL v2-licensed software cannot be bundled
with non-GPL v2 software in a collection of software, or that if it is, then
all the software must be relicensed under the GPL v2. Again, this is false.
Section 2 of the GPL v2 states that such *mere aggregations* are not
governed as a whole by the conditions of the licence.
I haven't checed but I am pretty sure that python must link to some GPL C
more from the GPL FAQ:
*If a program combines public-domain code with GPL-covered code, can I take
the public-domain part and use it as public domain code?*
You can do that, if you can figure out which part is the public domain part
and separate it from the rest. If code was put in the public domain by its
developer, it is in the public domain no matter where it has been.
BTW gnu readline, which I think ipython uses, is GPL software.another link:
I hope this links, although not sufficient to educate a decision on how to
mix licenses, may help to steer this discussion in the right direction.
Anyone else has further experience with BSD code linking GPL code?
