    This extension is the (very much updated) code for everything to
do with ruby from the AIE game "Hail" that isn't wrapping an Imagin8
engine class. It is known to work on Windows and Linux.

    The package contains:

        An FAQ about Hail (the game), ruby, and open-source software

        Timer: provides millisecond accurate timing from a
         hardware clock.

        Log: a unified debug log for c++ and ruby.

        Memory: a screaming fast memory pool allocation system.
         On win2k seems to be around 6* faster than malloc/free,
         and on (a very optimised) linux 2.4.19 around 2*.

        Vector3: a basic 3d vector class that is very easy
         and fast from c++ and very easy from ruby.

        Scheduler: Allows deferred execution of ruby code-blocks.
         If your event loop runs fast enough it is accurate to
         the millisecond, otherwise it catches up. Based on a
         scheduler by Roger Dannenberg for interactive music
         systems and midi sequencing.

        Signal: Like a Signal/Slot framework, but lets you
         connect to any number of ruby code-blocks.

        RubyMM: An exception safe c++ to ruby communication library.
         Lets you use any ruby class/instance/module from c++ with
         minimal effort, and hence makes it easy to write c++
         classes with virtual ruby methods. Also eases embedding
         ruby in a c++ application.

        Audio: a realtime 3d game audio engine written with the above
         classes and Fmod. Makes it easy to embed all the sounds an
         entity can make inside that entity, and allows control of
         all those sounds at once though a Manager.

    Fmod is a free-as-in-beer for non-commercial use audio abstraction lib
available from www.fmod.org. Here are some of its features:

    *If supported by your soundcard/drivers/platform you get hardware
     accelerated 2d/3d audio with environmental reverbs (EAX 3.0). If
     not you get MMX/FPU 2d/3d audio.
    *Runs on windows, wince, linux, macos, playstation2, game cube,
     and xbox.
    *On linux it can use OSS/Free, ESD, and ALSA 0.9
    *On windows it can use WinMM, DirectSound, ASIO, and DolbyDigital.
    *On all platforms it understands wav, aiff, mp3, ogg, and wma
     formats.
    *Lots more like mod, midi, and audio-cd playback (not available
     from ruby yet).
