<p>Functions which parse the command-line arguments, create the display,
kick everything off and then close down Mutter when it's time to go.</p>
<p>Mutter - a boring window manager for the adult in you</p>
<p>Many window managers are like Marshmallow Froot Loops; Mutter
is like Frosted Flakes: it's still plain old corn, but dusted
with some sugar.</p>
<p>The best way to get a handle on how the whole system fits together
is discussed in doc/code-overview.txt; if you're looking for functions
to investigate, read <code class="function">main()</code>, <code class="function">meta_display_open()</code>, and <code class="function">event_callback()</code>.</p>

<p>Stops Mutter. This tells the event loop to stop processing; it is
rather dangerous to use this because this will leave the user with
no window manager. We generally do this only if, for example, the
session manager asks us to; we assume the session manager knows
what it's talking about.</p>
