    A business template allows to construct ERP5 modules

    - dependency

    - conflicts

    - catalog definition ( -> formal definition + sql files )
      - SQL methods including:
        - purpose (catalog, uncatalog, etc.)
        - filter definition
      - Mapping definition
        - id (ex. getTitle)
        - column_id (ex. title)
        - indexed
        - preferred table (ex. catalog)

      - actions

    - module definition ( -> zexp/xml file)
      - id
      - relative_url

      - workflow_id
      - XML/XMI definition
      - relevant portal_types

    - tool definition ( -> formal definition)

    - categories definition

    Each definition should be usable in both import and update mode.

    Technology:

    - download a zip file (from the web, from a CVS repository)

    - install files to the right location (publish / update) (in the ZODB)

    - PUBLISH: publish method allows to publish an application (and share code)
      publication in a CVS repository allows to develop

      THIS IS THE MOST IMPORTANT CONCEPT

    Use case:

    - install core ERP5 (the minimum)

    - go to "BT" menu. Refresh list. Select BT. Click register.

    - go to "BT" menu. Select register BT. Define params. Click install / update.

    - go to "BT" menu. Create new BT. Define BT elements (workflow, methods, attributes, etc.). Click publish. Provide URL.
