Ah, I see what you're getting at now! I was not proposing that the
action field be for verbs.  It's not what action to _perform_, It's for
matching on what action is _being_ performed (ie, login or logout). 
Ignore my first proposal (extended fbtab syntax) entirely.  The only
features of that which I'm proposing we add here is access to the group
information, and having login and logout handled in a single file, with
an "action" field to for rules to match on.

I think we're all agreed then, we just didn't know it ;-)

However, now I'm thinking we should go even simpler, and just call a
script with the appropriate variables.  (see other message) Why invent
new syntax when we have sh, which already has globbing, etc? This does
add more overhead, though.
