#	CGI script for a page counter. To invoke in your HTML page
#	use:	<img source=cgi-bin/counter.cgi?counter_file.dat>
#
#	The file should contain the digits of the count (eg: "00123")
#	and the file should have write permissions for all.
#
#	Inspired by an article in February '97 "Linux Journal" 
#	written by Michel Vanaken.
