It took only four years to be released ! This is mtrack, originally named for Motif-track, but in the period 1996 to 1999 it has lain on my hard disc unloved and unwanted. But it is back, modified to use the GTK+ widgets and revamped for the new millenium. It goes without saying that in order to build this program, you need a functioning X windows system as well as the GTK toolkit, for more information about them look at http://www.gtk.org/. Mtrack is a satellite tracking program. No more and no less, it is under the GNU Public license and is therefore free to use, distribute and modify as you see fit. The program is based on a DOS program I wrote called microtrack which worked with Hercules video displays. The README.old file you find included went with that version and is a reasonable guide as to the facilities and usage of this version. I have grand plans to enhance the program further, but it all depends on time available to me and of course enthusiasm. Please look at the TODO file, as at least one of the projects requires no programming experience (writing the help files). Please note that using older versions of GTK+ can produce problems. I recommend that you try and get the latest version that you can. My development was done with GTK+ version 1.2.2. Jonathan HB9DRD/G4KLX
