HOW TO BUILD?

  An ANSI C compiler is required for build.

  To build, it should be easy.  There are 3 types.  You may want to set some
    parameters like SCOREPATH, SCOREFILE, LOGPATH, and LOGFILE.

    configure:
      Use "configure -help" to see what options you can set using configure
      or parameters in Makefile.in .

      configure ; make

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

      xmkmf ; make

    make.com (VMS users only):
      You may want to set parameters in make.com .

      @make

  Then just run "xskewb".  If you do a "make install" "SCOREPATH" and
  "LOGPATH" must be set correctly.

  You should copy Skewb.ad to $(HOME)/Skewb or use "make install" to
  copy it to something like /usr/lib/X11/app-defaults/Skewb, especially
  if the background is similar to one of the faces.  Edit this file for
  your preferences.

  There are a few install options using configure.
  make install:
    Normal installation usually in /usr/local.  The problem is that the
    file skewb.scores should be writable by the application but not
    users.  It will try to fallback to reading and writing in the current
    directory.  (skewb.log is a temporary log file to keep track of
    moves, here the current directory is the default with /usr/tmp as the
    fallback).
  make install-games:
    This will install the puzzle like the BSD games.  This configuration
    is for the most part hard coded and will ignore most prefix settings.
    The difference here is that it runs setgid.  This then has some
    "medium" security risks.

  The following installation options are used when the above ones are working.
  make install-png:
    This is used to install the "*.skewb.png" images for use with menus
    in Gnome and KDE.
  make install-xpm:
    This is used to install the "skewb.?.xpm" images for use with menus
    in CDE using system files (name changes from ".xpm" to ".pm" when
    installing).  The xpm images are the same the png images except the small
    image is 24x24 instead of 22x22.
  make install-xpm-home:
    This is used to install the images for use with menus in CDE using
    from your home directory.  I have this set up using the desktop and
    menus.  There are probably many ways but I have it set up using
    $HOME/.dt/types/dtfile.dt, $HOME/.dt/types/dtwm.fp, and $HOME/.dt/dtwmrc
    These files can be copied and changed from /usr/dt.
  Try resizing the puzzle. 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
  be able to duplicate the them.

  Much left to do for GL including:
    orienting faces
    see actual twisting
    Moving whole cube needs fixing
    Mouse interface.
    Junk the sudo 3d interface when GL is done.
