<div id="text-1.1">
<p>
The spherelib python package relies on healpy python package
(<a href="https://github.com/healpy/healpy">https://github.com/healpy/healpy</a>) and Healpix C++ library.
The Healpix software provides both (<a href="http://sourceforge.net/projects/healpix/">http://sourceforge.net/projects/healpix/</a>)
The healpy package can also be installed through <code>pip</code> tools.
</p>
<p>
The following libraries are also required:
</p><ul>
<li>
<b>GSL</b>
</li>
<li>
<b>FFTW3</b>
</li>
</ul>
<p>The <b>swig</b> program is used to interface c++ with python, together with the numpy
core headers (in particular numpy/arrayobject.h)
