13th October, 2014 - Release S4/1.03 (Standard 4, manual added)
Finally added the instructions manual browser. Thanks to Eddie Slattery for
providing great quality scans; several optimizations to the source code;
added a brand new splash screen, allowing to hide/display it at the next
startup.

5th May, 2014 - Release S4/1.02 (Standard 4, complete rewrite)
Completely rewritten source code in order to do major optimizazions; designed
new graphics; updated to the new standard "S4"; normalized sound samples
volume to a higher level; fixed several bugs; added the new "About" screen;
removed instructions manual at low resolution (now looking for better scans).

11th September, 2001 - Release S3/1.01 (Standard 3, minor bug-fix)
Fixed a small bug in game speed routines. Game could hand after reaching
100 points score; should be OK now :-(
