1.7 Donating

If you find this program useful, please send a donation to its developers to support their work. If you use this program at your workplace, please suggest that the company make a donation. We appreciate contributions of any size – donations enable us to spend more time working on this package, and help cover our infrastructure expenses.

If you’d like to make a donation of any value, please send it to the following Bitcoin address:


Since we aren’t a tax-exempt organization, we can’t offer you a tax deduction, but for all donations over 0.05 BTC, we’d be happy to recognize your contribution on the donors page and on DONORS file for the next release.

We are also happy to consider making particular improvements or changes, or giving specific technical assistance, in return for a substantial donation over 0.5 BTC. If you would like to discuss this possibility, write to me at

Another possibility is to pay a software maintenance fee. Again, write to me about this at to discuss how much you want to pay and how much maintenance we can offer in return.

Thanks for your support!
