Instead of specifying a particular kind of terminal (e.g. xterm, kterminal, xfterm), maybe specify a script which can be modified, or even just specify a symbolic link that can be redirected to different terminal emulators.
That's just a five-second idea so it might not come to anything, but I can see it working... somehow... some way
I understand what you are saying but we need it to work with the default term. For example if I remove kde from backtrack and install xfce4 , it needs to work with the default stuff. Thats the whole point of FDF compliance. I do appreciate your input though as I know you are a good programmer and have xfce4 experience
