Read well the readme file
You will use it together with txt2gtk which copies paste the heights back and forward to the gtk.
You can zoom a lot in graced so you can refine very well all the heights and give a personality to your track
For what I reacall, to make gtkalt work, you need a pic in the working directory, or something like that...
A good use of both of them should be to assing cambers with gtkalt (it gives to all the traces the camber angle you want) and after start using gracED (wich is only graphical so is harder to give the right camber angle, but not impossible ).
There is a new tool HeightED, developed by electricman on the base of gracED, wich should give good performance but I didn't try it very well, so I can't tell if you'll work faster with this one
