<dl>
<dd>
find an object that accepts the "app" message in the current context
</dd>
<dd>
find an object that accepts the "wikis" message in the "app" context
</dd>
<dd>
pass the last object a message that has one argument with a value of 'en.wikipedia.org'
</dd>
</dl>
</dd>
</dl>
<ul>
<li>
Note that instances/methods can return itself. This allows chaining multiple message calls.
</li>
</ul>
<dl>
<dd>
For example, in <code>app.wikis.get('en.wikipedia.org').files.cfg_download</code>, enabled_ and redownload_ both return the cfg_download object. This allows the following call
