## Good License Choice

<a id="license-approved"></a>
Obviously, code that's not under a license that is both
[OSI approved](http://opensource.org/licenses/alphabetical) and is not
[approved by FSF as a Free Software license](http://www.gnu.org/licenses/license-list.html#SoftwareLicenses)
is completely useless to us.

<a id="gpl-compatible"></a>
It would also be quite preferable if the code were under a
[a license that FSF has determined is GPL-compatible](http://www.gnu.org/licenses/license-list.html#GPLCompatibleLicenses),
so that code from GPL'd projects can be easily shared and GPL'd applications
can be built on top of anything we build.  Code not under a GPL-compatible
license would face a high burden (i.e., the code would really have to be
absolutely wonderful in all other respects) to dictate such a license choice.
