In the very early days of Akonadi, there actually was a command line client, 
but it got abandoned with the introduction of akonadiconsole. The code can 
still be found in playground/pim/akonadi/akonadicli. Many things have changed 
in Akonadi since then, so I'm not sure how much of this is still valid.
