"RhubarbTart is a light object publishing web framework built on WSGI and Paste. RhubarbTart is based on the CherryPy object publishing model. It is light and simple, using WSGI components from Paste to compliment the object publishing system with other features typical of a web framework"This could be an interesting alternative to CherryPaste, provided we (I for one centenary do) want Paste before CherryPy 3.0.
