8 incorporates the changes between \fIrev1\fR and \fIrev2\fR of an
9 RCS file into the corresponding working file. If \fB\-p\fR is given, the result
10 is printed on the standard output, otherwise the result overwrites the
13 A file name ending in ',v' is an RCS file name, otherwise a
14 working file name. \fIMerge\fR derives the working file name from the RCS
15 file name and vice versa, as explained in
18 of both an RCS and a working file name may also be specified.
20 \fIRev1\fR may not be omitted. If \fIrev2\fR is omitted, the latest
21 revision on the default branch (normally the highest branch on the trunk)
23 Both \fIrev1\fR and \fIrev2\fR may be given numerically or symbolically.
25 \fIRcsmerge\fR prints a warning if there are overlaps, and delimits
26 the overlapping regions as explained in \fIco \-j\fR.
27 The command is useful for incorporating changes into a checked-out revision.
29 Suppose you have released revision 2.8 of f.c. Assume
30 furthermore that you just completed revision 3.4, when you receive
31 updates to release 2.8 from someone else.
32 To combine the updates to 2.8 and your changes between 2.8 and 3.4,
33 put the updates to 2.8 into file f.c and execute
35 .B " rcsmerge \-p \-r2.8 \-r3.4 f.c >f.merged.c
37 Then examine f.merged.c.
38 Alternatively, if you want to save the updates to 2.8 in the RCS file,
39 check them in as revision 2.8.1.1 and execute \fIco \-j\fR:
41 .B " ci \-r2.8.1.1 f.c
43 .B " co \-r3.4 \-j2.8:2.8.1.1 f.c
45 As another example, the following command undoes the changes
46 between revision 2.4 and 2.8 in your currently checked out revision
49 .B " rcsmerge \-r2.8 \-r2.4 f.c
51 Note the order of the arguments, and that f.c will be
