WYAE - FormMail Counter

I came across a webpage where someone was counting typical attack
signatures of worms: http://www.zerodeux.net/projects/wormstat/
(Un)fortunately my provider seems to filter them out before they reach
my logs. 

On the other hand I keep on getting requests for old/vulnerable
FormMail CGI scripts (see http://www.spin.it/spam/formmail.php3
for explanation). So I built the following counter which gives me
a list in format "WEEK COUNT" which I then process in an
appropriate PHP webpage for nice layout.


Requirements
	* Unix shell and usual text tools (fgrep, zcat)
	* PHP or CGI for nice web page generation
