Bro - connection flags

I always forget to remember the conn flags url on Bro site. So, keeping "conn.log" flags state as a reference:

conn_state     Meaning
-----------     --------
S0         Connection attempt seen, no reply.
S1         Connection established, not terminated.
SF         Normal establishment and termination. Note that this is the same symbol as for state S1. You can tell the two apart because for S1 there will not be any byte counts in the summary, while for SF there will be.
REJ         Connection attempt rejected.
S2         Connection established and close attempt by originator seen (but no reply from responder).
S3         Connection established and close attempt by responder seen (but no reply from originator).
RSTO         Connection established, originator aborted (sent a RST).
RSTR         Responder sent a RST.
RSTOS0         Originator sent a SYN followed by a RST, we never saw a SYN-ACK from the responder.
RSTRH         Responder sent a SYN ACK followed by a RST, we never saw a SYN from the (purported) originator.
SH         Originator sent a SYN followed by a FIN, we never saw a SYN ACK from the responder (hence the connection was “half” open).
SHR         Responder sent a SYN ACK followed by a FIN, we never saw a SYN from the originator.
OTH         No SYN seen, just midstream traffic (a “partial connection” that was not later closed).
