-# First branch: login

-# I've never seen a cvr other than cvr0. Maybe this will be trouble later?
-# Can't anchor at the beginning because sometimes this is encapsulated in
-# HTTP. But either way, the first packet ends like this.
-# Second/Third branches: accepting/sending a message
-# I will assume that these can also be encapsulated in HTTP, although I have
-# not checked. Example of each direction:
-# ANS 1 quadong@hotmail.com 1139803431.29427 17522047
-# USR 1 quadong@hotmail.com 530423708.968145.366138

-# Branches are written entirely separately for performance reasons.
