I've spent a considerable amount of my spare time on coding Console2, versions up to 2.7 were released for free.
Version 3.x is almost free, there is a small twist, if you want to use it you'll need a license.
But I don't want your money, I've decided to make v3.x charityware, it means that if you want to use v3.x you'll need to donate $100 USD to a charity of your choice.
If you want to give more, go ahead, I won't stop you. :-)
Find a charity you like, if you want to help people or animals, it doesn't matter.
Before donating/requesting a license please read the license agreement that is part of the README file.
