The short script "helpdemo.g" illustrates the use of two new XODUS objects
which are particularly useful for incorporating interactive help into a
simulation.  The "ximage" graphical widget may be used to display bitmapped
images which have been saved in the GIF format.  Many personal computers
have programs for converting the output of scanners and paint or draw
programs into this highly compressed format.  (Note that *.gif files are
binary files.  When transferring these files by ftp, the mode should be set
to "binary".)  The "xtext" widget may be used to display a text file,
allowing the user to scroll through the file with mouse button clicks or
keystrokes.

If GENESIS has been properly installed, the command "genesis helpdemo"
should produce a "help" menu from which one may select four images and one
text file by clicking the left mouse button.  Each displayed graphical form
has a "DONE" button which may be clicked on to hide the form.
