            "content": "Reads  portable  anymaps  as input.  Concatenates them either left to right or top to bottom,\nand produces a portable anymap as output.\n\npamdice splits an image up into smaller ones.\n\npnmtile concatenates a single input image to itself repeatedly.\n\n",

        "OPTIONS": {
            "content": "If the anymaps are not all the same height (left-right) or width  (top-bottom),  the  smaller\nones have to be justified with the largest.  By default, they get centered, but you can spec‐\nify one side or the other with one of the -j* flags.  So, -topbottom -jleft would  stack  the\nanymaps on top of each other, flush with the left edge.\n\nThe  -white  and -black flags specify what color to use to fill in the extra space when doing\nthis justification.  If neither is specified, the program makes a guess.\n\nAll flags can be abbreviated to their shortest unique prefix.\n\n",
