# Scrolledtext
# ----------------------------------------------------------------------
# Implements a scrolled text widget with additional options to manage
# the vertical scrollbar. This includes options to control the method
# in which the scrollbar is displayed, i.e. statically or dynamically.
# Options also exist for adding a label to the scrolled text area and
# controlling its position. Import/export of methods are provided for
# file I/O.
