A new configuration of the MARC module with improved UI features, support for CCK, better caching and a new MARC API that can be used (but does not need to be used) to create nodes.
This branch of the MARC module is seeking to make the MARC module more useful and configurable across a number of applications. The initial MARC module was very limited in that its primary purpose was to turn MARC records in to nodes. The new branch breaks the marc record/node dependency and also has some nice new features like a batch importer.
