  It has been tested on the following platforms:

    Sun4 SPARC   SunOS 5.5.1  X11R5,X11R6
    DEC  VAX     VMS6.1       X11R5
    DEC  ALPHA   VMS6.1       X11R5
    HP   HPPA1.1 HP-UX 9.01   X11R5
    PC   486     Linux 1.2.13 X11R6(*)

    * Keypad may not work, since various keycodes may not be defined
      by default.  Check that "KP_1 - KP_9, Home, Up, Prior, Left,
      Begin, Right, End, Down, Next" are defined towards the end of
      /usr/lib/X11/etc/xmodmap.std .  If not defined
      cp /usr/lib/X11/etc/xmodmap.std /usr/lib/X11/xinit/.Xmodmap
      and then motify this or create your own at ${HOME}/.Xmodmap .
      You should just have to uncomment them (get rid of some '!').
      This should be done before X is started.  Also it may work better
      with the Num-Lock on.

  If you have to do any editing to get this to work, please mail me
  the changes.

HOW TO BUILD?

  An ANSI C compiler is required for build.

  To build, it should be easy.  There are 3 choices.

    configure:
      Relatively new so there is a good possiblity that it is not set up
      correctly on your system.  You may want to set SCOREFILE and DATAFILE
      in Makefile.in .

      configure ; make

    imake:
      Sometimes this is not setup correctly by the distributer ... i.e. not
      my fault.  You may want to set SCOREFILE and DATAFILE in Imakefile .
      If you have Motif you may want to do this quick edit in the Imakefile:
        Uncomment line "#define XpmLibrary".

      xmkmf ; make

    make.com (VMS users only):
      You may want to set SCOREFILE and DATAFILE in make.com .

      @make

  Then just run "xskewb" (or "xmskewb" if you have Motif).
  If you do a "make install" "SCOREFILE" and "DATAFILE" must be
  set correctly.

  You should have Skewb.ad copied to $(HOME)/Skewb or 
  /usr/lib/X11/app-defaults/Skewb to run, especially if the background
  is similar to one of the faces. Edit this file for your preferences.
  You might want to move xskewb into /usr/bin/X11 (or wherever your
  X binaries are).
  You might also want to move xskewb.man to /usr/man/man6/xskewb.6

  Try resizing the cube. Notice the puzzle resizes to take advantage
  of the "room" available.

  If you were looking for a auto-solver, sorry.  If you know of one
  let me know.

  Also a tesseract (4D cube) would be nice. (Does such an analog exist
  for 4d?)

  Personally, I have solved this puzzle, but only physically, never in
  software. The biggest handicap is that the puzzle is hard to follow
  through the diagonals. But the real one is like that too.

  Refer to the man page for detailed command line options.

  If you want further information on puzzles, I'll be glad :-) to send
  it to you.

FOUND A BUG?

  Send bugs reports and fixes to the author. For bugs, please include
  as much information as to their location as possible, since I may not
  have the resources to duplicate the them.

HISTORY

  [Jan 01, 97]  V5.4: Username, concurrency check, configure, man page
    updates.
  [Aug 01, 96]  V5.3.2: Fixed drag and drop bug.
  [Apr 08, 96]  V5.3: Minor changes.
  [Jan 31, 96]  V5.2: Puzzle can now moved by a more intuitive drag and
    drop approach.  Pieces will invert, when selected.
    New orthogonal moves make the turning more intuitive.
  [Dec 15, 95]  V5.1: Minor updates, RNG for 32/64 bit, border color
    to make faces look more realistic.
  [Oct 06, 95]  V5.0: Xt/Motif, your choice.
  [May 16, 95] V4.10: Warnings removed from Sun's cc and lint and now
    include a random number generator.  New control key moves
    added for the 2D version.
  [Mar 13, 95]  V4.6: Removed lint warnings and added a VMS make.com .
  [Nov 11, 94]  V4.5: Conservative guess for random number generator.
  [Oct 02, 94]  V4.4: Now allows undos, saves, and recalls.
  [Jun 28, 94]  V4.3: More reuse of code between 2D & 3D, can accommodate
    a auto-solver.
  [Jun 15, 94]  V4.2: Mistakenly used a Boolean variable in an array.
  [Jun 02, 94]  V4.1: R6.
  [May 30, 94]  V4.0: Xt version.
    I got some good ideas from oclock.
  [Oct 14, 93]  V3.0: Motif version.
    I got some good ideas from Douglas A. Young's
    book: "The X Window System Programming and Applications
    with Xt OSF/Motif Edition", particularly his dial widget.
    I got some good ideas on presentation from Q. Zhao's
    tetris.
  [Jan 22, 92]  V2.0: XView version.
  [Mar 19, 91]  V1.0: SunView version.
