importing a development version of a package from a specific directory
<p>I'm trying to load a development version of a popular Library into my project. Obviously they will have the same package name and therefore cannot co-exist without disambiguation.</p>

<p>My understanding of python module management doesn't go beyond site-packages, the module search path and standard import statements.</p>

<p>My code begins with the following imports:</p>

<pre><code>from IPython.frontend.qt.console.rich_ipython_widget import RichIPythonWidget
from IPython.frontend.qt.embedded_kernelmanager import QtEmbeddedKernelManager
from IPython.frontend.qt.kernelmanager import QtKernelManager
from IPython.lib import guisupport
</code></pre>

<p>How do I get the IPython symbol to point to a user supplied directory ? </p>
