Changes:
Version 0.1.0 (March 26 2004)
--------------------------------
    - Formally update project status to 'beta'.

    - Formally renamed APL to the "APL Package" and also renamed APL to
      stand for "Application Programming Layer"

    - Updated the uIP httpd server to support GET-action URLs.

    - Added a telnet deamon for uIP.  The deamon (based largely on the uIP
      deamon) provides hooks for a multi-threaded environment as well
      supporting TCP/IP flow-control. Also added a companion command
      shell infrastructre.

    - Added parsing/tokenizer primitives interface for identifing tokens
      and delimiters in a string.

    - Added parsing/tokenizer interface for parsing encoded URLs that are
      generated by a HTML GET action.

    - Added a trace-logging interface for good ole printf debugging that
      can be 'compiled out' for production releases.

    - Ported light-weight TCP/IP Stack, lwIP, to APL.  Direct support for
      running uIP on the ESP-HBDB01, EDOSK2674 eval boards and Unix.
      Note: lwIP is able to run under Unix/Linux, so you can develop
      networking apps using APL/lwIP on your workstation before moving to an
      embedded target.

    - Added a 'stdout' interface that defines a APL version of printf.  This
      allows the platform to define what its standard-output-device is
      (serial port, file descriptor, etc.).

    - Add true semaphore and mutex factory support the XMK port of the
      OS Abstraction layer.

    - Updated the mutex interface with helper macros for 'safe' locking of
      the Exclusive mutex.

    - Added a Thread Worker Pool Interface.

    - Added a thread-specific-data (TSD) interface to the OS Abstraction
      layer.

    - Added yet another ITC interface.  The new interface, SMBOX, is much
      simpler, less featured ITC interface that imposes limits on the size
      of the mailbox FIFO queues.

    - Bug Fixes:
      o Update all of the H8 test/example projects to allocate stack memory
        using 16bit integer arrays to ensure proper alignment.
      o Fix race condition in all of the ITC Mailboxes interfaces where
        waiting-with-a-timeout could leave the thread-semaphore in
        the wrong state (i.e. signaled when it should have been not-signaled).
      o Fix the POSIX and WIN32 OS factory implementations to actually
        match the create semantics instead of throwing fatal errors.
      o Fix plat-mapping for Aplmt_isExclusiveLocked() under XMK (the
        polarity was wrong).
      o Aplmt_isExclusiveLocked() did not work properly under Win32
      o Fix the Posix/Aplmt/itc projects so that main.c calls the test
        application correctly.
