Unbanning Matching Duplicate entry to reduce Banlist

[Zohaib]

I was looking for a Script in which if a New banmask is placed on previously banned banmask it will remove the old ban.

for example if this ban already existed in the banlist :

* XmIRC sets mode: +b *!*@207.97.174.134

and Someone bans again with different banmask i.e

* XmIRC sets mode: +bb *!*@*.secureserver.net *!*@207.97.174.*

the bot checks for duplicate bans and remove the old ones

* XmIRC sets mode: -bk *!*@207.97.174.134 Duplicate.Entry.Unbanned

I have seen this script being used on mIRC based bots, is it possible to make a similar script in tcl too?

thanks.
