   'psudoku' is a program to generate Sudoku puzzles in PostScript
form (hence the name:  'ps' = 'PostScript').  These can be converted
to PDF using the 'pdf2ps' utility.

   By default,  the conventional 9x9 cell puzzle is generated,  but
other types of sizes 4x4 to 30x30 can be generated.

   Puzzles can be generated in a variety of layouts,  such as four
puzzles on one page with the solutions shown in a smaller size
upside down at the bottom;  or many puzzles on three pages with a
fourth "solutions" page;  and so on.

   You can select the level of difficulty of a puzzle,  ranging from
"requires only simplest methods" to "you'll have to guess to fill in
certain cells".

   On the command line,  one can add the '-g(grid name)' option to select
the puzzle type.  By default,  this is '-g9' (conventional 9x9 puzzle
broken into nine 3x3 blocks).  '-g12' would provide a 12x12 puzzle broken
into twelve 4x3 blocks,  '-g16' a 16x16 puzzle broken into sixteen 4x4
blocks,  and so on.

   Following are the puzzle types currently supported with the '-g'
option. In each case,  the grid size is given,  and the NxN grid is
split into N blocks of N cells each.  In some cases,  these grids are
regular. In others,  that's not possible;  for example,  in the 7x7
Sudoku,  you can't arrange seven cells in some truly logical order. 
And in some cases,  a couple of different possible layouts are
provided; thus, there is an '8',  '8a',  '8b',  and '8c'.

4 5 6 6a 7 8 8a 8b 8c 9 9a 10 11 12 12a 12b 12c 12d 13 13a 13b
14 14a 14b 15 16 17 17a 17b 18 18a 20 21 21a 24 24a 25 27a 28 30

   The larger puzzles aren't all that practical to solve,  but it was
interesting to get the program to be able to generate them in some
reasonable amount of time.
