release notes:

  Too much fun, these bits and baubles...


README excerpt:

  This is a collection of small programs released
  under GNU GPL v3 that use Guile-SDL, available at:

  NB: These require Guile-SDL 0.4.0 or later.

NEWS excerpt:

  - 4.0 | 2012-02-14

    - distribution now .tar.xz

        If you have GNU tar, you can use "tar xf" and it will DTRT.
        If not, you can use "xz -dc TARBALL | tar xf -" to unpack.

    - new ‘demo’ option ‘--list’

        This lists the available demo programs, one per line.  Also,
        ‘--help’ no longer does that, suggesting ‘--list’ instead.

    - changes to demo ‘view-vcg’

      - default geometry now 800x600

        You can still achieve the old default geometry, of course, by
        invoking with the option ‘-g 300x400’.

      - background stars

        This demonstrates another panning method than that provided by
        ‘(sdl misc-utils) toroidal-panner/3p’, which as it turns out, is
        not up to the task for compositing ‘SRCCOLORKEY’ surfaces.  :-/
        Probably this upstart will find its way into a Guile-SDL release
        sooner or later.

      - new option ‘--depth N’

        The default starfield depth is 3, but you can specify another
        with the new option ‘--depth N’.  High depth works but is ugly.
        Specifying a zero depth effectively disables background stars.

        Additionally, the relative motion (for depth two or higher) of
        the starfields demonstrates parallax.

    - new demo ‘robots’

        This is a "loose port" (re-implementation of original behavior
        without actually having experienced the original) of GNU Robots,
        using data from GNU Robots 1.2.0 -- please see AUTHORS.

        It doesn't demonstrate anything particularly novel, just the
        power of Procrastination and Other People's Free Software.
