    Folks,

    I am proud to announce the release of the Protothreads Library version
    1.0:
                      http://www.sics.se/~adam/pt/

    Protothreads are extremely lightweight stackless threads designed for
    severely memory constrained systems such as small embedded systems or
    sensor network nodes. Protothreads provide linear code execution for
    event-driven systems implemented in C. Protothreads can be used with
    or without an underlying operating system.

    Protothreads provide a blocking context on top of an event-driven
    system, without the overhead of per-thread stacks. The purpose of
    protothreads is to implement sequential flow of control without
    complex state machines or full multi-threading. Protothreads provide
    conditional blocking inside C functions.

    Main features:

        * No machine specific code - the protothreads library is pure C
        * Does not use error-prone functions such as longjmp()
        * Very small RAM overhead - only two bytes per protothread
        * Can be used with or without an OS
        * Provides blocking wait without full multi-threading or
          stack-switching
        * Freely available under a BSD-like open source license

    Example applications:

        * Memory constrained embedded systems
        * Event-driven protocol stacks
        * Sensor network nodes

    The protothreads library is released under an open source BSD-style
    license that allows for both non-commercial and commercial usage. The
    protothreads library was written by Adam Dunkels <adam@sics.se>
    with support from Oliver Schmidt <ol.sc@web.de>.
