	      <p>$PROGRAM is an original development of <a href="http://www.darold.net/">Gilles Darold</a>.</p>
	      <p>Some parts of the collector are taken from <a href="https://github.com/gleu/pgstats">pgstats</a> a C program writen by Guillaume Lelarge and especially the SQL queries including the compatibility with all PostgreSQL versions.</p>
	      <p>Btw $PROGRAM grapher is compatible with files generated by pgstats, sar and sadc so you can use it independently to graph those data. Some part of the sar output parser are taken from <a href="http://sysusage.darold.net/">SysUsage</a></p>
