 <p>The files in idlelib are described in idlelib/README.txt.  Access it
 either in idlelib or click Help =&gt; About IDLE on the IDLE menu.  This
 file also maps IDLE menu items to the code that implements the item.
 Except for files listed under ‘Startup’, the idlelib code is ‘private’ in
 sense that feature changes can be backported (see <span class="target" id="index-7"></span><a class="pep reference external" href="https://peps.python.org/pep-0434/"><strong>PEP 434</strong></a>).</p>
