In fact, the zip contains ONLY the two executables with names
gnubg-gui-py-sse.exe and gnubg-nogui-py-sse.exe, so you need to
unzip them into an existing installation.
But doing so will not overwrite your existing exes (named
gnubg.exe and gnubg-cli.exe), you'll have both versions (your
'old' one and the new MT one).

Has the MT code any effect on the "Evaluation speed" test ("calibrate" in
the command-line version) ?
I think the answer is no, but maybe that's the thing we should
use to roughly evaluate the benefits of multi-threading ....
