<h3 class="section">4.4 Caveats</h3>
<p><code>Sketch</code> is a fairly powerful tool for drawing, but, just as with
TeX, the power to create beautiful results comes along with the
power to make mistakes.  The following are some points where care is
necessary and where the current version of <code>sketch</code> is limited or
has known bugs.
