[Bro-Dev] question & meta-question regarding "path" field in smtp.log

[Vern Paxson]

The question is: what's the semantics of this log field?  In the
trace slice I'm looking at, it's just the server,client.  Is it meant
to have the Received chain?

The meta-question is: how am I supposed to find documentation for stuff
like this?  Searching on "smtp path" from bro-ids.org didn't bring up
obvious hits.  It wasn't that hard to navigate my way to:

	http://bro-ids.org/documentation-beta/bro-scripts/scripts/base/protocols/smtp/main.html

but there all I find is a listing of the type of "path", but not its meaning:

	path: vector &log &optional

Is this just because the documentation hasn't yet caught up this far?
