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

  80. <p>The auto-loading feature is useful for supplying application-specific
  81. debugging commands and features.
  82. </p>
  83. <p>Auto-loading can be enabled or disabled,
  84. and the list of auto-loaded scripts can be printed.
  85. See the &lsquo;<samp>auto-loading</samp>&rsquo; section of each extension language
  86. for more information.

  90. <p>Note that loading of this script file also requires accordingly configured
