All of these programs are free software
and you have no moral or legal obligation to provide me with money or
anything else for the use of these programs. If however you feel you
would like to contribute something for any of programs please send that
money to the Free Software Foundation
instead, either as a normal donation
or by joining as an associate member.
If you drop me an e-mail to let me know you've done this I will be far
more inspired than if I had the cash in my hand.
