/*
   AltIcon is really nice program and Its tutorial led me to write this
very simple program. What it does is....
   Splits the icon that was combined as a dual-action icon with Alticon
into two separate icons that you can then edit separately and THEN
recombine if you wish.
   This program was brought about by a friend who wanted to improve on
someone elses imagary... Well Den.... Here it is.....

                      SPLITICON  !!!!

To use it, first compile the program (It works under Lattice, have no idea
about MANX) and link it.
