[Linux-bruxelles] check your vote

If the software isn't changed from last year, and the clock on the 
machine is set correctly, you can easily declare the elections invalid:

check the first 8 bytes read from the magnetic card, and look it up in 
the output of the program below. It should correspond to the time of 
your vote. (Even if the time is set correctly, it could be off by one 
or two hours dpending on timezone or DLS).

Confront the chairman with your result and ask him to declare the vote 
illegal, as it cannot guarantee your anonymity.
