# Implements a source display widget using primitive widgets as the
# building blocks.
#
# The main display for SrcWin is a SrcTextWin widget.  This file
# should contain all the code for controlling the SrcTextWin.
# SrcTextWin should just display the requested file and lines, without
# having to be very intelligent.  If there are problems, error codes
# should be returned and SrcWin should figure out what to do.
