--- Comments ------------
-------------------------

The original game has been written by Sparctacus ( I don't know his real
name ), it was in a library.

I had to do many changes to produce the improved version.
The improved version has been almost completely re-written, and thus
it is better :

 - it is a stand alone prog.
 - bugs are removed.
 - sound has been added.
 - it works on all HP48. ( Thanks to D. Cannon's help )
 - it is a lot smaller.
 - it is faster ( not the game but the ML-routines ).

There are still a little bug, but it is hard to make it appear.
This bug is due to the way the datas are stored.
I couln't fix it without changing the whole datas structure.


-------------------------
--- Keys to use ---------
-------------------------

The keys are :

 - 8 & 2 : Left and right.
 - 5     : Rotate.
 - 2     : Drop.
 - 6     : Next level.
 - DEL   : Pause.
 - +/-   : Toggle sound on/off.
 - ON    : Exit.

I suppose you already guessed the HP must be hold with the screen
on the left.
