345347Ssos.SH DESCRIPTION
355347Ssos.B rcsdiff
365347Ssosruns
375347Ssos.BR diff (1)
385347Ssosto compare two revisions of each \*r file given.
395347Ssos.PP
405347SsosPathnames matching an \*r suffix denote \*r files;
415347Ssosall others denote working files.
425347SsosNames are paired as explained in
435347Ssos.BR ci (1).
445347Ssos.PP
455347SsosThe option
465347Ssos.B \-q
475347Ssossuppresses diagnostic output.
485347SsosZero, one, or two revisions may be specified with
495347Ssos.BR \-r .
505347SsosThe option
515347Ssos.BI \-k subst
525347Ssosaffects keyword substitution when extracting
535347Ssosrevisions, as described in
545347Ssos.BR co (1);
555347Ssosfor example,
565347Ssos.B "\-kk\ \-r1.1\ \-r1.2"
575347Ssosignores differences in keyword values when comparing revisions
585347Ssos.B 1.1
595347Ssosand
605347Ssos.BR 1.2 .
6143334SyokotaTo avoid excess output from locker name substitution,
625347Ssos.B \-kkvl
6332822Syokotais assumed if (1) at most one revision option is given,
645347Ssos(2) no
655347Ssos.B \-k
665347Ssosoption is given, (3)
675347Ssos.B \-kkv
685347Ssosis the default keyword substitution, and
695347Ssos(4) the working file's mode would be produced by
705347Ssos.BR "co\ \-l".
