       rcsmerge - merge RCS revisions

       rcsmerge [options] file

       rcsmerge	 incorporates the changes between two revisions of an RCS file
       into the corresponding working file.

       Filenames matching an RCS suffix denote RCS files;  all	others	denote
       working files.  Names are paired as explained in ci(1).

       At  least  one  revision	 must  be  specified  with  one of the options
       described below, usually -r.  At most two revisions may	be  specified.
       If  only	 one revision is specified, the latest revision on the default
       branch (normally the highest branch on the trunk) is  assumed  for  the
       second  revision.   Revisions  may be specified numerically or symboli‐

       rcsmerge prints a warning if there are overlaps, and delimits the over‐
       lapping	regions	 as  explained in merge(1).  The command is useful for
       incorporating changes into a checked-out revision.

       -A     Output conflicts using the -A style of diff3(1), if supported by
	      diff3.  This merges all changes leading from file2 to file3 into
	      file1, and generates the most verbose output.

       -E, -e These options specify conflict styles that generate less	infor‐
	      mation  than  -A.	 See diff3(1) for details.  The default is -E.
	      With -e, rcsmerge does not warn about conflicts.

	      Use subst style keyword substitution.  See  co(1)	 for  details.
	      For example, -kk -r1.1 -r1.2 ignores differences in keyword val‐
	      ues when merging the changes from 1.1 to 1.2.  It normally  does
	      not  make	 sense	to merge binary files as if they were text, so
	      rcsmerge refuses to merge files if -kb expansion is used.

	      Send the result to standard output instead  of  overwriting  the
	      working file.

	      Run quietly; do not print diagnostics.

	      Merge  with  respect  to revision rev.  Here an empty rev stands
	      for the latest revision on  the  default	branch,	 normally  the

       -T     This  option has no effect; it is present for compatibility with
	      other RCS commands.

       -V     Print RCS's version number.

       -Vn    Emulate RCS version n.  See co(1) for details.

	      Use suffixes to characterize RCS files.  See ci(1) for details.

       -zzone Use zone as the time zone for keyword substitution.   See	 co(1)
	      for details.

       Suppose you have released revision 2.8 of f.c.  Assume furthermore that
       after you complete an unreleased revision 3.4, you receive  updates  to
       release	2.8 from someone else.	To combine the updates to 2.8 and your
       changes between 2.8 and 3.4, put the updates to 2.8 into file  f.c  and

	   rcsmerge  -p	 -r2.8	-r3.4  f.c  >f.merged.c

       Then  examine  f.merged.c.   Alternatively,  if	you  want  to save the
       updates to 2.8 in the RCS file, check them in as revision  and
       execute co -j:

	   ci  -r2.8.1.1  f.c
	   co  -r3.4  -j2.8:  f.c

       As  another  example,  the following command undoes the changes between
       revision 2.4 and 2.8 in your currently checked out revision in f.c.

	   rcsmerge  -r2.8  -r2.4  f.c

       Note the order of the arguments, and that f.c will be overwritten.

	      Options prepended to the argument list, separated by spaces.   A
	      backslash	 escapes spaces within an option.  The RCSINIT options
	      are prepended to the argument lists of most RCS commands.	  Use‐
	      ful RCSINIT options include -q, -V, -x, and -z.

	      An  integer lim, measured in kilobytes, specifying the threshold
	      under which commands will try to use memory-based operations for
	      processing  the  RCS file.  (For RCS files of size lim kilobytes
	      or greater, RCS will use the slower standard  input/output  rou‐
	      tines.)  Default value is 256.

       TMPDIR Name  of	the  temporary directory.  If not set, the environment
	      variables TMP and TEMP are inspected instead and the first value
	      found  is	 taken;	 if  none  of  them  are set, a host-dependent
	      default is used, typically /tmp.

       Exit status is 0 for no overlaps, 1 for some overlaps, 2 for trouble.
