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
