OT: how to read BIND's debug file (named.run)

[Doug Poland]

Hello,

I realize this is not FreeBSD specific, other than the fact that I'm
running BIND on 1/2 dozen FreeBSD 6.2 servers.  But I'd like to know
if someone knows of a resource to help me interpret what I'm seeing in
BIND's debug output file.

For example:

# rndc trace
# rndc querylog
# tail /var/named/etc/named/named.run

client 192.168.1.21#65193: query: example.com IN AAAA +
client 192.168.1.21#53443: query: example.com IN A +
client 192.168.1.21#50255: query: example.com IN MX +
client 192.168.1.7#59639: query: hostname.example.com IN A +
client 192.168.1.7#61740: query: hostname.example.com IN AAAA +
client 192.168.1.7#56778: query: hostname.example.com IN A +
client 192.168.1.7#64564: query: hostname.example.com IN AAAA +
client 192.168.1.19#32776: query: ns2.example.com IN AAAA -
client 192.168.1.19#32776: query: ns1.example.com IN AAAA -
client 192.168.1.13#39132: query: example.org IN MX -E
client 192.168.1.11#32783: query: www.example.com IN A -


I trimmed out date/time stamp and it's obvious what the client,
IP#port, query: name are for.  Also, I get what the: IN  A MX  SOA 
PTR flags are.  But what do the following characters mean?

-
+
AAAA -
AAAA +
-E

I googled and did a little experimenting with dig but sure would be
nice if there's a document out there that describes all these.
