a's 4 liner works as expected from the command line, but from CGI in framechat, it doesn't find $ENV{TEMP} on my system, neither does tye's line. So, rather than gamble with the location of $temp it's been made a config variable that defaults to the script directory, so people with restrictive environments can easily set it.

I see what you mean about the 'magic' $comment global. It's really just an artifact of the development process, it was needed at first but eventually coded out of relevance.

Update:

(an obsolete patch that was here has been deleted)
