It doesn't really matter. So 'add' is
apparently a built-in exclusion. I went for 'adds' because that's what a reasonable amount of kobo mods and apps use. This by itself already requires the proper exclusion line to be present in the .conf file.
In fact, anyone could change the installation directory by editing 'usr\local\kobocloud\config_kobo.sh' from within the package.
