       command.  The `source` parameter is required for this provider, and should
       be set to the absolute path (on the puppet agent machine) of a directory
       containing one or more BFF package files.

       The `installp` command will generate a table of contents file (named `.toc`)
       in this directory, and the `name` parameter (or resource title) that you
       specify for your `package` resource must match a package name that exists
       in the `.toc` file.

       Note that package downgrades are *not* supported; if your resource specifies
       a specific version number and there is already a newer version of the package
       installed on the machine, the resource will fail with an error message."
