+SUMMARY="A fast and thorough lazy object proxy for Python"
+DESCRIPTION="lazy-object-proxy is based on the ObjectProxy from the wrapt \
+Python module with one big change: it calls a function the first time the \
+proxy object is used, while wrapt.ObjectProxy just forwards the method calls \
+to the target object"
