Subject: Re: bin/32340: rs doesn't parse options POSIXly
Date: Mon, 19 Dec 2005 18:38:09 +0100

 Here is a patch that helps with the mandatory option arguments.
 getopt is not applicable since options like -S and -C may
 be used without argument.
 
 N.B. the options  -o, -B and -b are not documented in the manpage.
