       pnmcat - concatenate portable anymaps


       pnmcat [-white|-black] -leftright|-lr [-jtop|-jbottom] pnmfile pnmfile ...
       pnmcat [-white|-black] -topbottom|-tb [-jleft|-jright] pnmfile pnmfile ...


       Reads portable anymaps as input.  Concatenates them either left to right or top to bottom,
       and produces a portable anymap as output.

       pamdice splits an image up into smaller ones.

       pnmtile concatenates a single input image to itself repeatedly.


       If the anymaps are not all the same height (left-right) or width (top-bottom), the smaller
       ones  have  to  be justified with the largest.  By default, they get centered, but you can
       specify one side or the other with one of the -j*  flags.   So,  -topbottom  -jleft  would
       stack the anymaps on top of each other, flush with the left edge.

       The  -white  and  -black  flags  specify what color to use to fill in the extra space when
       doing this justification.  If neither is specified, the program makes a guess.

       All flags can be abbreviated to their shortest unique prefix.
