For use, start the "xdiff" binary with "-?" to show parameters.
To make it work, the included adiff must be in the path, since
xdiff will call it to compare files.
If you're using a lower resolution, you can move the "XDiff.ad"-file
to "X11:lib/x11/app-defaults/XDiff" and choose a smaller font there,
such as: "xdiff*text.fontList: 5x7" (notice removed '!'-comment).

Required software:
- the AmiWin-X11 software package
