+/*
+ * Main program for the standalone picture generator. To use it,
+ * simply provide it with an XBM-format bitmap file (note XBM, not
+ * XPM) on standard input, and it will output a game ID in return.
+ * For example:
+ *
+ * $ ./patternpicture < calligraphic-A.xbm
+ * 15x15:2/4/2/2/2/3/3/3.1/3.1/3.1/11/14/12/6/1/2/2/3/4/5/1.3/2.3/1.3/2.3/1.4/9/1.1.3/2.2.3/5.4/3.2
+ *
+ * That looks easy, of course - all the program has done is to count
+ * up the clue numbers! But in fact, it's done more than that: it's
+ * also checked that the result is uniquely soluble from just the
+ * numbers. If it hadn't been, then it would have also left some
+ * filled squares in the playing area as extra clues.
+ *
+ * $ ./patternpicture < cube.xbm
+ * 15x15:10/2.1/1.1.1/1.1.1/1.1.1/1.1.1/1.1.1/1.1.1/1.1.1/1.10/1.1.1/1.1.1/1.1.1/2.1/10/10/1.2/1.1.1/1.1.1/1.1.1/10.1/1.1.1/1.1.1/1.1.1/1.1.1/1.1.1/1.1.1/1.1.1/1.2/10,TNINzzzzGNzw
+ *
+ * This enables a reasonably convenient design workflow for coming up
+ * with pictorial Pattern puzzles which _are_ uniquely soluble without
+ * those inelegant pre-filled squares. Fire up a bitmap editor (X11
+ * bitmap(1) is good enough), save a trial .xbm, and then test it by
+ * running a command along the lines of
+ *
+ * $ ./pattern $(./patternpicture < test.xbm)
+ *
+ * If the resulting window pops up with some pre-filled squares, then
+ * that tells you which parts of the image are giving rise to
+ * ambiguities, so try making tweaks in those areas, try the test
+ * command again, and see if it helps. Once you have a design for
+ * which the Pattern starting grid comes out empty, there's your game
+ * ID.
