<p>I am making an API server that allows hot-deploying of code. And yes, there are dozens of questions about re-importing modules. I just want to monitor a directory, and when a change is detected, perform an action.</p>

<pre><code>path_to_monitor="c:\\app\\package"
def action():
    do_something()
dm=dir_monitor(path_to_monitor,action)
dm.start()
</code></pre>

<p>I need a solution that is mature and cross-platform.</p>
