+# 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 better performance.
