[rtags] Allow to 'derive' rtags Since some releases, rtags (structure underlying uicfg) have selector and may be copied using something like: new_rtags = deepcopy(original_rtags) new_rtags.__module__ = __name__ new_rtags.__select__ = custom_selector The problem is that starting from that, both rtags wil diverge and changes in original_rtags won't be considered, while we usually want to set a few specific rules only in new_rtags. To fix this problem, this cset introduces the notion of "derivated/parent" rtag, eg: new_rtags = original_rtags.derive(__name__, custom_selector) Beside easier copying, when using the above method changes in original_rtags which are not overriden by new_rtags will be considered since it only hold its specific rules but look among its parent chain for non-found keys. Along the way, flake8 unittest_rtags. Closes #16164880

Pyramid Cubicweb
================

Pyramid Cubicweb is an attempt to rebase the CubicWeb framework on pyramid.

It can be used in two different ways:

-   Within CubicWeb, through the 'pyramid' cube and the
    :ref:`pyramid command <cubicweb-ctl_pyramid>`.
    In this mode, the Pyramid CubicWeb replaces some parts of
    CubicWeb and make the pyramid api available to the cubes.

-   Within a pyramid application, it provides easy access to a CubicWeb
    instance and registry.
