I am not at all prepared to deal with regular expressions so when this one came up in a paypal script I found myself unable to find out what it does. Any help appreciated.

$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;

It is used on the value of a POST from the paypal webserver when they are being read into a hash

Also, if I have a script where should I post so that others can access it (source code wise, not execution).
