Z:englobe-dpkg-man--7c8341-Check for the existence of a s/es

Check for the existence of a specified process. If such a process exists, B does nothing, and exits with error status 1 (0 if B<--oknodo> is specified). If such a process does not exist, it starts an instance, using either the executable specified by B<--exec>, (or, if specified, by B<--startas>). Any arguments given after B<--> on the command line are passed unmodified to the program being started.
