I'm in Wikipedia!

I've a great fan of Wikipedia and have contributed one or two snippets (one on the near sinking of the Queen Mary by a giant wave, which was kept secret because it was wartime), but a casual search reveals that I'm actually in it (and I'm chuffed). If you search for zzapper (my Internet Id) you'll find my notes on ZSH are referenced. ZSH is an advanced shell used on Unix/Linux computers systems.
