DESCRIPTION

       This package allows scrollbars to be mapped and unmapped as needed depending on the size and content of the scrollbars scrolled widget. The
       scrollbar must be managed by either pack or grid, other geometry managers are not supported.

       When managed by pack, any geometry changes made in the scrollbars parent between the time a scrollbar is unmapped, and when  it	is  mapped
       will  be  lost. It is an error to destroy any of the scrollbars siblings while the scrollbar is unmapped. When managed by grid, if anything
       becomes gridded in the same row and column the scrollbar occupied it will be replaced by the scrollbar when remapped.

       This package may be used on any scrollbar-like widget as long as it supports the set subcommand in the same style as scrollbar. If the  set
       subcommand is not used then this package will have no effect.

       ::autoscroll::autoscroll scrollbar
	      Arranges for the already existing scrollbar scrollbar to be mapped and unmapped as needed.

       ::autoscroll::unautoscroll scrollbar
	      Returns the named scrollbar to its original static state.

       ::autoscroll::wrap
	      Arranges for all scrollbars created after this command is run to be automatically mapped and unmapped as needed.

       ::autoscroll::unwrap
	      Turns off the automatic autoscrolling of all new scrollbars.  Does not effect existing scrollbars

	      text .t -yscrollcommand ".scrolly set"
	      scrollbar .scrolly -orient v -command ".t yview"
	      pack .scrolly -side right -fill y
	      pack .t -side left -fill both -expand 1
	      ::autoscroll::autoscroll .scrolly
