 - 
 - <p>Guile is an implementation of the Scheme programming language
 - and is the GNU project’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.
