** Description **

The Scrollutil package contains:

   * the implementation of the '''scrollarea''', '''scrollsync''', and '''scrollableframe''' mega-widgets, including a general utility module for mega-widgets;

   * commands for ''user-friendly'' mouse wheel event handling in '''scrollable widget containers''' like scrollutil::scrollableframe, BWidget ScrollableFrame, and iwidgets::scrolledframe;

   * demo scripts illustrating the use of the Scrollutil package in connection with various scrollable widgets and the above-mentioned scrollable widget containers;

   * a programmer's guide and reference pages in HTML format.

'''The scrollutil::scrollarea mega-widget''' greatly simplifies the creation of arbitrary scrolled widgets.  It consists of a scrollable widget and two scrollbars connected with that widget.  The display mode of each scrollbar can be `'''static'''`, `'''dynamic'''`, or `'''none'''`.

'''The scrollutil::scrollsync mega-widget''' is designed for scrolling several widgets simultaneously.  It is horizontally and vertically scrollable, hence it can be embedded into a scrollutil::scrollarea widget via the latter's `'''setwidget'''` subcommand.

'''The scrollutil::scrollableframe mega-widget''' is a lightweight, theme-able, and full-featured replacement for BWidget ScrollableFrame and  iwidgets::scrolledframe.  Arbitrary regions of its content frame  can be brought into view by scrolling, and the widget also provides a `'''see'''` subcommand for making individual widgets contained in the content frame visible in the scrollableframe window.
