``pp.core`` implements some core foundation functionalities
of the Produce & Publish framework.
+This module abstracts Produce & Publish basic functionality in order to make
+the core implementation as re-usable as possible. It uses the ``pyfilesystem``
+to abstract arbitrary file operations independent of the underlaying storage
+layer. Through this approach we are able to support local filesystems, network
+filesystems or cloud storages like Dropbox without changing the application.
+All storage subsystems can be accessed using the same API.
