        Subcommands:

        list: List the active configuration (or from the file specified)
        edit: Edit the configuration file in an editor
        get: Get the value associated with name
        set: Set the name=value
        unset: Unset the value associated with name

        If none of --user, --global and --site are passed, a virtual
        environment configuration file is used if one is active and the file
        exists. Otherwise, all modifications happen on the to the user file by
        default.
