  28         <h4 id="basic">Basic Configuration Options - the <tt>configure</tt> utility</h4>
  29         <p>The following options are for compiling and installing a working version of the NTP distribution. In most cases, the build process is completely automatic. In some cases where memory space is at a premium, or the binaries are to be installed in a different place, it is possible to tailor the configuration to remove such features as reference clock driver support, debugging support, and so forth.</p>
  30         <p>Configuration options are specified as arguments to the <tt>configure</tt> script. Following is a summary of the current options, as of the 4.0.99m version:</p>
  31         <p>Usage: <tt>configure [options] [host]</tt><br>
