Pyxr
An object-relational mapping-ish wrapper around Xlib ad X's resource manager/xrdb
How to Use
Pyxr provides only one class: pyxr.Namespace.
That takes two optional arguments: The namespace to operate in (* by default) and the display address, which Xlib will pick on its own if unspecified.
Then, you access members of the xrdb class name as if they were attributes of the Namespace instance. They'll be written, read and deleted as you go.
