    A business template allows to construct ERP5 modules

    It may include:

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

    - portal_types definition
      - object without optinal actions
      - list of relation between portal type and worklfow

    - module definition

      - portal type

    - site property definition

    - document/propertysheet/extension/test 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,
      from local file system) (import/donwload)

    - 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
