    description = """
        Odoo cloc is a tool to count the number of relevant lines written
        in Python, Javascript or XML. This can be used as rough metric for
        pricing maintenance of customizations.

        It has two modes of operation, either by providing a path:

            odoo-bin cloc -p module_path

        Or by providing the name of a database:

            odoo-bin --addons-path=dirs cloc -d database

        In the latter mode, only the custom code is accounted for.
