documentation build.
  * test doc: added missing svn:ignore entries.

   because libtool under OS X sucks.

    the DVD drive instead of giving up.

    of Bernard Leak with a few additions.

    reworked from a 

    MPlayer team.

    dynamically loaded functions and gets rid of lvalue casts.

    + Save the cached key as ASCII in hexadecimal form.
    + Overwrite cached files if the data was invalid.

    + Recreate the cache dir information on each launch, in case the
      information it contains ever changes.

    + Support for cache directory tags, as proposed on
      http://www.brynosaurus.com/cachedir/spec.html .

    + Append the disc key to the cache directory name to avoid issues with
      identical discs which have different encryption keys, thanks to Sven
      Heithecker.
    + Use - instead of # as a separator in the cache filename.

    + Run libtoolize before aclocal.
    + Support automake 1.8.

  * doc/.cvsignore: Ignore stamp files.

    + Store the off_t values for seek and read in a temporary variable to
      work around a strange gentoo gcc behaviour as seen here:
