Prepare for installation of `games` demo programs. Fix inconsistencies and typos in man pages. In the future the man pages can be installed together with the executables. This will be done in a later commit. documentation/src/glpuzzle.man: new file.

.SH SYNOPSIS
|
|
\fISudoku\fR is a FLTK-based version of the game of Sudoku.
|
|
Sudoku (pronounced soo-dough-coo with the emphasis on the first
|
|
syllable) is a simple number-based puzzle/game played on a 9x9
|
|
grid that is divided into 3x3 subgrids. The goal is to enter a
|
|
number from 1 to 9 in each cell so that each number appears only
|
|
once in each column, row, and subgrid.
|
|
.LP
|
|
At the start of a new game, Sudoku fills in a random selection of
|
|
cells for you - the number of cells depends on the difficulty
|
|
level you use. Click in any of the empty cells or use the arrow
|
|
keys to highlight individual cells and press a number from 1 to 9
|
|
to fill in the cell. To clear a cell, press 0, Delete, or
|
|
Backspace. When you have successfully completed all subgrids,
|
|
the entire puzzle is highlighted until you start a new game.
|
|
.LP
|
|
As you work to complete the puzzle, you can display possible
|
|
solutions inside each cell by holding the Shift key and pressing
|
|
each number in turn. Repeat the process to remove individual
|
|
numbers, or press a number without the Shift key to replace them
|
|
with the actual number to use.
