#+STARTUP: nofold

** Overview and Motivation

** Concepts
*** What is a process, what are event handlers?
*** What is a VM?
*** Subscription and Advertisement
**** orientation
**** topics, patterns and messages
**** interest-type
**** roles
*** Presence
*** Nesting, relaying, and levels of discourse

** High-level interface
*** #lang marketplace
**** ground-vm, ground-vm:
*** Constructing topics and roles
**** ?
**** Role
**** Orientation
**** InterestType
*** Constructing transitions
**** transition, transition:, transition/no-state
**** cons-trees of actions; null, false, void; use of (when)
**** sequence-actions
*** Actions
**** Communication-related
***** endpoint, endpoint:
***** delete-endpoint
***** send-message
***** send-feedback
**** Process- and scheduling-related
***** spawn, spawn:
***** quit
***** yield, yield:
***** nested-vm, nested-vm:
**** Cross-layer

** Low-level interface
*** Handler functions
*** Events
*** Actions
**** Communication-related
***** add-endpoint
***** delete-endpoint
***** send-message
**** Process- and scheduling-related
***** spawn
***** quit
***** yield
**** Cross-layer
***** at-meta-level

** How the VMs work
*** run-vm
*** unification and Racket data (struct-map)
*** nested VMs
*** ground VMs and interfacing to Racket's event system

** Drivers
*** event-relay
*** tcp-bare
*** tcp
*** timer (typed and untyped)
*** udp (typed and untyped)

** Writing new drivers
*** pseudo-substruct

** Management and monitoring
*** generic-spy
*** logging (MATRIX_LOG)
*** debugger (experimental)

** Example Applications
*** TCP echo server
*** TCP chat server
*** Authoritative DNS server
*** DNS resolver server
*** SSH server
