    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 cloc --addons-path=dirs -d database

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