This saves a count of accesses and returns a single line of javascript.
This writes the number into the webpage.
Insert the following entry into your page :
<script language=JavaScript src="http://www.voidspace.xennos.com/cgi-bin/webcounter.py?site=SITENAME"></script>
That will use the version hosted on my server.
Replace SITENAME with something that is likely to be unique.
