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
