<p><small>GDB</small> provides two mechanisms for automatically loading extensions
when a new object file is read (for example, due to the <code>file</code>
command, or because the inferior has loaded a shared library):
<samp><var>objfile</var>-gdb.<var>ext</var></samp> and the <code>.debug_gdb_scripts</code>
section of modern file formats like ELF.

<p>The auto-loading feature is useful for supplying application-specific
debugging commands and features.
</p>
<p>Auto-loading can be enabled or disabled,
and the list of auto-loaded scripts can be printed.
See the &lsquo;<samp>auto-loading</samp>&rsquo; section of each extension language
for more information.
For <small>GDB</small> command files see <a href="Auto_002dloading-sequences.html#Auto_002dloading-sequences">Auto-loading sequences</a>.
For Python files see <a href="Python-Auto_002dloading.html#Python-Auto_002dloading">Python Auto-loading</a>.
</p>
<p>Note that loading of this script file also requires accordingly configured
<code>auto-load safe-path</code> (see <a href="Auto_002dloading-safe-path.html#Auto_002dloading-safe-path">Auto-loading safe path</a>).
