Could I use Cython with 3rdparty pure python library?
<p>I'm using Python to develop a commercial software.
But I don't want to offer source to my clients.</p>

<p>I knew that Cython can complie my code to binary.</p>

<p>But could I use Cython with 3rdparty pure python library(I mean those libraries written in pure Python)?</p>
