Wow, I thought some current httrack options were obscure ; 
but here I don't know how I would explain that in the 
FAQs :))

Anyway this is an interesting idea ; but rather difficult 
to implement ; it's like including PC-regular-expressions 
in httrack; quite interesting, but too tricky and also 
complex for the end-user (MANY users don't understand how 
current scan rules work ; the #1 question is "how can I 
grab missing pictures"). But anyway I'll think a little 
more and see if (maybe a simplfied form) it can be 
possible. But not in the near future, anyway (the priority 
is stabilizing and including "urgent" missing features)
