the external **notmuch-<subcommand>** in :envvar:`PATH` instead. This
allows users to have their own notmuch related tools to be run via the
notmuch command. By design, this does not allow notmuch's own commands
-to be overridden using external commands.
+to be overridden using external commands. The environment variable
+:envvar:`NOTMUCH_CONFIG` will be set according to :option:`--config`,
