This is a tool used to get a list with content paths in alf_data for content needed to preserve consistency in the repository. This is very usable if there for example is a need to debug an alfresco installation where the error is not easy to replicate with the small dataset of a development environment. This way you can transfer a whole production contentstore (with the major content property stripped). The structure will be intact but all files will be of 0 bytes (except the ones needed as explained below).
