   1 /*
   2  * upsstats - cgi program to generate the main UPS info page
   3  *
   4  * Author: Russell Kroll <rkroll@exploits.org>
   5  *
   6  * To use: install the binary in a directory where CGI programs may be
   7  *       executed by your web server.  On many systems something like
   8  *       /usr/local/etc/httpd/cgi-bin will work nicely.  I recommend
   9  *         calling the binary "upsstats.cgi" in that directory.
  10  *
  11  *       Assuming a path like the above, the following link will suffice:
  12  *         <A HREF="/cgi-bin/upsstats.cgi">UPS Status</A>
  13  *
  14  *       This program assumes that upsimage.cgi will be in the same
  15  *       directory.  The install-cgi target will take care of putting
  16  *       things in the right place if you set the paths properly in the
  17  *       Makefile.
  18  *
  19  * Modified: Jonathan Benson <jbenson@technologist.com>
  20  *         19/6/98 to suit apcupsd
  21  *         23/6/98 added more graphs and menu options
  22  *
  23  * Modified: Kern Sibbald <kern@sibbald.com>
  24  *        Nov 1999 to work with apcupsd networking and
  25  *                 to include as much of the NUT code
  26  *                   as possible.
  27  *                 added runtim status
