 <h3 id="additional-remarks-from-the-judges">Additional remarks from the judges:</h3>
 <p>The author provided us with the following notes and new version of
 the program:</p>
-<p>Here is a somewhat improved version of my tetris entry. All the
-changes are in the <code>popen()</code> at the end. Formerly a move was done
-to the HI score file which is not permitted for other users. Now
-other users can change the <code>HI</code> score file. The extra option <code>-m</code> is
-passed to sort, so that it knows that its input files are already
-sorted. The <code>-o</code> output option of sort is used instead of a
-temporary file.</p>
-<p>You may also want to consider giving just the raw option to <code>stty</code>
-at the start and <code>-raw</code> at the end. This further reduces the size of
-the program, but has the possible disadvantage that the program
-can only by stopped by ‘q’ or by the `kill -9’ command.</p>
