NAME
     xtetris - X Window block dropping game

SYNOPSIS
     xtetris [ X options ]

DESCRIPTION
     Xtetris is a game involving dropping blocks.  As  they  drop
     you  can  move  them to the left or to the right by clicking
     the left or right mouse buttons respectively.  Pressing  the
     shift key while clicking the button causes the falling shape
     to rotate anti-clockwise (left mouse  button)  or  clockwise
     (right  mouse  button).  Pressing  the  middle  mouse button
     causes the shape to quickly drop. Note that the  mouse  must
     be  in the window in which the shapes are dropping for these
     actions to work correctly.

     You can also use the keyboard: h for moving to the  left,  l
     for  moving to the right, j to rotate clockwise, k to rotate
     counter-clockwise and space for dropping quickly..

     You can also use the direction pad,  if  your  keyboard  has
     one:  (Left)  to move left, (Down) to rotate clockwise, (Up)
     to rotate counter clockwise, and (Right) to move right.

     Points are scored for each block that comes to rest  on  the
     gradually  building  up  pile of blocks. Different blocks in
     different orientations have different point values. When the
     pile reaches the top of the screen and no further blocks can
     be dropped the game ends. When a row of  blocks  across  the
     screen is completely filled, that row is removed and all the
     blocks above it drop down.  As more  rows  are  deleted  the
     blocks drop faster.

     A high  score  table  is  kept  which  is  retained  between
     separate  executions  of  the game.  You can avoid recording
     your score, by using the -noscore option.

     Xtetris requires the installation of an application defaults
     file,     probably    in    the    file    /usr/lib/X11/app-
     defaults/Xtetris. If that file does not exist, xtetris  can-
     not  run.  (It will probably print out something like "Width
     zero.  Terminating.")  Almost everything about  xtetris  can
     be  configured  in  your .X11defaults file.  You can use the
     application defaults file as a guide,  until  some  generous
     soul updates this man page to describe everything.

AUTHORS
     This version of xtetris has accumulated the work of  several
     individuals.

     Adam Marguilies <vespa@ssyx.ucsc.edu> wrote the  first  non-
     graphics version.

     Phill Everson <everson@cs.bris.ac.uk>  and  Martyn  Shortley
     <shortley@cs.bris.ac.uk> posted a later non-graphics version
     of tetris to comp.sources.games in March 1989.

     Didier Tallot <tallot@bdblues.altair.fr> built an X11 graph-
     ics  xtetris  from  the  non-graphics  tetris around 29 May,
     1989.  It used the unsupported Xw (HP) widget set.

     Dan  Greening  <dgreen@cs.ucla.edu>  rewrote  much  of   the
     xtetris code to produce version 2.0.
