*
* ToDo:
*
* - The whole NOAA space weather www site is pretty screwed up! I currently have
* to grab data from 2 separate files to get all that I need. But it seems that
* sometimes one of the files shows less than it should. This seems to be related to
* the way they update the 2 separate files... I will have to find some way of
* making that more robust.
*
*
*
*
*
*
*
*
*
* Changes:
*
* Version 1.04 - released Feb 18, 1999
* Added double click capability. Double clicking on mouse button 1 sends
* URL (defined via ne command line option -url) to netscape.
*
* Version 1.03 - released Feb 11, 1999
* Changed display a bit. When no data is
* available, it now shows nothing (before it would
* show false junk...). Modified Perl Script GetKp.
*
*
* Version 1.02 - released Feb 8, 1999
* bug fixes...
*
* Version 1.0b - released Dec 19, 1998
