    A business template allows to construct ERP5 modules

    - catalog definition
      - SQL method objects
      - SQL methods including:
        - purpose (catalog, uncatalog, etc.)
        - filter definition

    The Business Template properties are exported to the bt folder with

    Technology:

    - download a gzip file or folder tree (from the web, from a CVS repository,

    - install files to the right location (install)

    Use case:

    - install core ERP5 (the minimum)

    - go to "BT" menu. Import BT. Select imported BT. Click install.

    - go to "BT" menu. Create new BT.
      Define BT elements (workflow, methods, attributes, etc.).
      Build BT and export or save it
