The source code for GeDoSaTo is now online at:
It includes a (rather short) developer Readme. The code base is, in my opinion, in a much better state than DSfix and DPfix, though I wouldn’t call it “clean” still. But it shouldn’t be too hard to get into.
I hope everyone who has sent me technically detailed mails about potential improvements (and everyone else interested of course!) will contribute!
The best way of contributing is using the GitHub facilities. That is, fork the project, add your improvements, and gather and document them into a pull request. As I wrote in the readme, if you plan to add a major new feature, it would be very helpful if you could contact me before (e.g. by email with a suitable subject line) so that we can discuss the design and not duplicate any work.
