Subject: question about --tcp-flags

I only want to know how iptables uses this option. For example
--tpc-flags SYN,ACK,RST SYN how is it then used? Am I right that the
flags SYN,ACK,RST are inspected and only the SYN flag is allowed to be
set? Or is it so that SYN,ACK,RST are inspected and the SYN flag must be
set but the other are optional so that all can be set but only SYN has
to be set? I´m a little confused :). And another question what flags
cobos are allowed/not allowed. I only know about a few so SYN,RST set is
an illegal set also SYN,FIN. Or SYN,ACK when initiating a connection.
Thank´s in advance for replies.
