1This module is meant to be built alone and not added to the Opensim code base. References are made to required dlls through a
2reference file, ContentManagement.mdp. Originally, for development, this project was contained in the Opensim/Region/Modules/

5To compile: nant
6To use: Copy ContentManagement.dll into the bin directory of your Opensim build. You should find many other dlls in the same directory.
