<h4 class="subsection">23.3.1 Guile Introduction</h4>

<p>Guile is an implementation of the Scheme programming language
and is the GNU project&rsquo;s official extension language.
</p>
<p>Guile support in <small>GDB</small> follows the Python support in <small>GDB</small>
reasonably closely, so concepts there should carry over.
However, some things are done differently where it makes sense.
</p>
<p><small>GDB</small> requires Guile version 3.0, 2.2, or 2.0.
</p>
<a name="index-guile-scripts-directory"></a>
<p>Guile scripts used by <small>GDB</small> should be installed in
<samp><var>data-directory</var>/guile</samp>, where <var>data-directory</var> is
the data directory as determined at <small>GDB</small> startup (see <a href="Data-Files.html#Data-Files">Data Files</a>).
This directory, known as the <em>guile directory</em>,
is automatically added to the Guile Search Path in order to allow
the Guile interpreter to locate all scripts installed at this location.
