Header  (change his line to cause an update)
This is a demo of an applet that reads text from a text file and scrolls the
text vertically.
<P>
The text file is checked periodically for changes, and if a change to the header
(the first line of text in the file) occurs then the text that is being scrolled 
in the applet is dynamically refreshed.
<P>
Currently, this applet is configured to check to text file every 60 seconds and
to display an indicator in the top left corner of the applet for each read.
<P>
(Normally an update check would occur much less frequently unless the text file
is being constantly updated.)
