XCol is a program to edit occurrences of color-names in text-files (i.e. the '.twmrc'-file). It shows the available colors and you can change the textfile by selecting new colors with the mouse. Even without editing a textfile, it gives you a good impression of the available colors (the colors defined in the 'rgb.txt'-file of the server). Use make to build the program. As there is only one Source-Modul you can also use 'cc xcol.c -lX11 -o xcol'. The program runs on X11R4. It should run on X11R3 too, but I already had some small problems with the created colormap.
