Placement(1x)						   AfterStep X11 window manager 					     Placement(1x)

NAME
       Placement - AfterStep supports several different window placement policies. Some of them designed to fill free space, and some allowing for
       windows to be placed on top of others.

CONFIGURATION OPTIONS
       Cascade

	      Windows will be placed in cascading order.

       Manual

	      Windows must be placed manually.

       RandomPlacement

	      Windows will be placed randomply, in space unobstructed by windows that have AvoidCover attribute set.

       SmartPlacement

	      Most suitable free space area will be chosen to place window in. If no such area is found of sufficient size - window will be placed
	      using secondary placement strategy, or manually, if no secondary strategy is specified.

       Tile

	      Windows  will be tiled in free space. If no space of suitable size is found, then secondary placement strategy is engaged, or window
	      will have to be placed manually. This is similar to SmartPlacement,  except  that  suitable  space  is  chosen  following  direction
	      left-to-right, top-to-bottom, instead of looking for space, most fitting the window size (the way SmartPlacement works).
