Protocol analyzers
For a TCP protocol analyzer the template generated the following declaration in
analyzer/*.evt:
protocol analyzer Foo over TCP:
parse originator with foo::Request,
parse responder with foo::Response;
Here we declare a Zeek protocol analyzer Foo which uses to different parsers
for the originator (client) and responder (server) side of the connection,
Request and Response. To use the same parser for both sides we would declare
parse with foo::Messages;
