[ic] custom logging

[David Etheredge]

I want to add some custom logging to each of my sites that run interchange.

I have been doing this on some other sites with a perl based cgi. Is there a 
good place in the cart.cgi to add this where this log can be written?

The log file is written with the following:  localtime() 
$ENV{'REMOTE_ADDR'}  $ENV{'HTTP_REFERER'})   Query String   Affiliate_ID(if 
any)  subject(if any) ;
I prefer to keep this separate from other logs as I use it to keep PPC and 
Affiliate programs honest which requires that I sort the list.
