The primary source of documentation is the code itself, of course. And, it is as comforting as it is empowering to know that it is possible to read through the entire sources for all of Gizmo, QP and Durus in one pleasant weekend. Nonetheless, for convenience, specific topics will be condensed into dedicated notes, and accumulated here. All help, suggestions, and write-ups, are most welcome.
QP and Durus mailing lists
In addition to docs contained here and in the distribution, Gizmo and QP issues may be discussed on the QP mailing list, while Durus-specific issues may be discussed on the durus-users mailing list.
