.SH DESCRIPTION
.PP
2ls10 is a small clone of the popular game '2048'. 
.PP
You start on a square grid (4x4 cells by default). At the beginning, two
of the cells contain either a '2' or a '4'. The aim of the game is to 
shift the cells around (left, down, up, right), until you get a cell
with a '2048'.
.PP
The classic `h-j-k-l` keys are used to slide cells left, down, up,
right, respectively. 
.PP
When you shift the cells in one direction, any two adjacent
cells along that direction that contain the same number are 'merged'
into a single cell containing twice that number. After each movement,
a new number (either a 2 or a 4) is placed in one of the empty cells,
chosen uniformly at random.
.PP
The game ends where there are no more moves left (in which case you
lost), or when there is at least one cell with a '2048' (which counts as
a win).
.PP
It should be clear now why the executable is called `2ls10`. 
.SH ARGUMENTS
.TP 5m
.BI [n]
An optional integer
.BI n
(larger than 1 and smaller than 16) can be passed as first argument to
set the size of the grid. The default is n=4. Larger grids are normally
easier to solve. A 4x4 grid is the smallest one where you can get ever a
2048.
.SH BUGS
At difference with the original game, a new ramdom cell is filled even
if the user attempted to shift the cells in a direction where no shifts 
are allowed.
