<h2 class="chapter">28 <small>GDB</small> Annotations</h2>

<p>This chapter describes annotations in <small>GDB</small>.  Annotations were
designed to interface <small>GDB</small> to graphical user interfaces or other
similar programs which want to interact with <small>GDB</small> at a
relatively high level.
</p>
<p>The annotation mechanism has largely been superseded by <small>GDB/MI</small>
(see <a href="GDB_002fMI.html#GDB_002fMI">GDB/MI</a>).
