83This is the automatically generated usage text for ntpsweep.
84
85  <p>The text printed is the same whether selected with the <code>help</code> option
86(<span class="option">--help</span>) or the <code>more-help</code> option (<span class="option">--more-help</span>).  <code>more-help</code> will print
87the usage text by passing it through a pager program. 
88<code>more-help</code> is disabled on platforms without a working
89<code>fork(2)</code> function.  The <code>PAGER</code> environment variable is
90used to select the program, defaulting to <span class="file">more</span>.  Both will exit
91with a status code of 0.
