Recently I forgot the option how to restart a service with svc:

develop:~ # svc
develop:~ # svc -h
develop:~ # cvs --help
Usage: cvs [cvs-options] command [command-options-and-arguments]
  where cvs-options are -q, -n, etc.
...
develop:~ # svc --help
develop:~ # man svc
No manual entry for svc
develop:~ # svc -whereisthedamnhelptext
svc: illegal option -- w
svc options: u up, d down, o once, x exit, p pause, c continue, h hup, a alarm, i interrupt, t term, k kill

Just my personal experience - might be wrongly installed. It's great software, but it has unnecessary annoyances, IMHO.
