I'm pleased to announce the first public release of gizmo(qp).

Gizmo extends the QP Web Framework (that by default uses Durus for
persistence), adding functionality to help with building rich and
exacting web interfaces.

Key features include:

- Unburden pages from the tasks of access control, templating, and
generation of contextual (where, who) navigational data. These are
taken care of independently & externally from the page.

- A DHTML Information class, that is contributed to by all participants
of a response, making complex DHTML pages easier to build and debug.

- Gizmos, that are user interface objects with client-side behaviour
and interaction. The gizmo api is a simple pattern for encapsulating
user interface objects that know how to cooperatively participate in
the page generation process.

- Gizmo Form, that supports automatic generation of redundant
client-side field validation as well as an additional json callback for
a field (when the field's validation logic requires server-side
business logic or data). A by-product of Gizmo Form is a simplified
JavaScript version of the generic spec python module, included in QP.

- Skins, in particular the GTi Skin, that supports format-agnostic
template files that may embed python expressions. GTi templates may
also liberally pull() in bits and pieces of other templates (or content
files, source code, or any textual source). This feature is really
handy for technical sites, with content that makes frequent references
to *live* code.

- Built-in Form Login, User Registration, and User Admin facilities.

- Comprehensive demo, also available live.
