You mean a script that uses the perl modules? We have one around which I 
just had some fun debugging (there's a debug in the "new protocol" support 
which we found Thursday, it will be fixed in 2.2.13). I'll find it.

No (well, yes, but only starting in 2.3 versions)

I know of none.

No

Sieve is an evolving language. Some syntax didn't exist at the beginning.

Of course, if you claim to prefer minimalism, why would you explicitly 
specify the default comparator? ;-)

It means no later rules will apply (so you won't have multiple copies 
filed)
