        <title>Description</title>

        <para>
            Updates an application or runtime. <arg choice="plain">NAME</arg> is the
            name of an installed application or runtime. Optionally,
            <arg choice="plain">BRANCH</arg> can be specified to update a
            specific branch, otherwise all installed branches are updated. If
            no <arg choice="plain">NAME</arg> is given, then everything installed
            is updated.
        </para>
        <para>
            By default this looks for both installed applications and
            runtimes, but you can limit this by using the --app or
            --runtime option.
        </para>
        <para>
            Normally, this command updates the application to the tip
            of its branch. But it is possible to check out another commit,
            with the --commit option.
        </para>
        <para>
            Note that updating a is different from installing
            a different branch, and runtime updates are expected to keep
            strict compatibility. If an application update does cause
            a problem, it is possible to go back to the previous
            version, with the --commit option.
        </para>
        <para>
            Unless overridden with the --user option, this command updates
            a system-wide installation.
