I use execute_with_notice for this in 1.5.. it was disabled in 2.0
because the notice_tags function is incomplete. I patched it a bit to
get it to work again but it needs to be finished..
I'm attaching the patch I had made.. I think it still works :-)
execute_with_notice is pretty easy to use... you just device a new
Notice::Action and hook things up to it. see here for example
the script you call just needs to getenv BRO_ARG_MSG BRO_ARG_SUB etc
