B/S Bingo

Here's the source. Copy to bsbingo.c and compile with some command such as
cc -o bsbingo bsbingo.c
Then use the commands given under usage (or package them in a little script and put a handy link on your desktop).
The resulting random 5x5 grid is used to relieve the tedium of an otherwise boring meeting.
