#: /etc/rc.d/init.d/rwalld:63 msgid "Usage: rwalld {start|stop|status|restart}" If "rwalld" is replaced with $0 here, this message can be reused in translations (other usage messages use $0), so that translators won't have to translate each similar message individually. To make it more clear, what I suggest is: "Usage: $0 {start|stop|status|restart}"
changed in rwall-0.17-7 and later.
