                      5: \fBrcsdiff\fR [ \fB\-biwt\fR ] [ \fB\-cefhn\fR ] [ \fB\-q\fR ] [ \fB\-r\fIrev1\fR ] [ \fB\-r\fIrev2\fR ] file ...
                      6: .SH DESCRIPTION
                      7: .I Rcsdiff

                      9: .IR diff (1)
                     10: to compare two revisions of each RCS file given.
                     11: A file name ending in ',v' is an RCS file name, otherwise a
                     12: working file name. \fIRcsdiff\fR derives the working file name from the RCS
                     13: file name and vice versa, as explained in
                     14: .IR co (1L).
                     15: Pairs consisting
                     16: of both an RCS and a working file name may also be specified.
                     17: .PP
                     18: The options \fB\-b\fR, \fB\-i\fR, \fB\-w\fR, \fB\-t\fR,
                     19: \fB\-c\fR, \fB\-e\fR, \fB\-f\fR, and \fB\-h\fR,
                     20: have the same effect as described in
                     21: .IR diff (1);
                     22: option
                     23: \fB\-n\fR generates an edit script of the format used by RCS.
                     24: The option \fB\-q\fR suppresses diagnostic output.
                     25: .PP
                     26: If both \fIrev1\fR and \fIrev2\fR
                     27: are omitted, \fIrcsdiff\fR compares the latest revision on the
                     28: default branch (normally the highest branch on the trunk)
                     29: with the contents of the corresponding working file. This is useful
                     30: for determining what you changed since the last checkin.
                     31: .PP
                     32: If \fIrev1\fR is given, but \fIrev2\fR is omitted,
                     33: \fIrcsdiff\fR compares revision \fIrev1\fR of the RCS file with
                     34: the contents of the corresponding working file.
                     35: .PP
                     36: If both \fIrev1\fR and \fIrev2\fR are given,
                     37: \fIrcsdiff\fR compares revisions \fIrev1\fR and \fIrev2\fR of the RCS file.
                     38: .PP
                     39: Both \fIrev1\fR and \fIrev2\fR may be given numerically or symbolically,
                     40: and may actually be attached to any of the options.
