<h2>Open Source</h2>
<br>
<p>
Apportable is powered by
<a href="http://www.fsf.org/">Free and Open Source Software</a>.
</p>
<p>
We are making portions of our platform available under an
<a href="http://www.gnu.org/licenses/lgpl.html">LGPLv3</a>
license so that others may
use and improve upon our code. These libraries
can be dynamically linked to proprietary software and are
distributed as separate binaries in Apportable applications.
</p>
<h2><a href="https://github.com/apportableinc/openal-soft">Fixed Point
OpenAL-soft</a></h2>
<p>
We forked
<a href="http://repo.or.cz/w/openal-soft.git">OpenAL-soft</a>
and improved audio performance on Android by
replacing floating point operations with fixed point operations.
</p>
<h2><a href="https://github.com/apportableinc/Foundation">Apportable
Foundation</a></h2>
<p>
We have developed our own version of the
NeXTSTEP/OpenStep Foundation APIs, combining code from the
<a href="http://www.gnustep.org/">GNUstep</a>
and
<a href="http://www.cocotron.org/">Cocotron</a>
projects.
