Python's sh module - Running 'source' command
<p>When using python's <a href="http://amoffat.github.io/sh/" rel="nofollow">sh</a> module, 
I would like to run a 'source' builtin command.</p>

<p>But I can't run it, because sh should have a binary as parameter.</p>

<p>How can I run builtin commands with sh module?</p>

<pre><code># source ./test.sh

sh.source('./test.sh') # wrong usage
sh.Command('source') # wrong usage
</code></pre>
