* NAME

   rcsdiff - compare RCS revisions

* SYNOPSIS

   rcsdiff [ -bcefhn ] [ -rrev1 ] [ -rrev2 ] file ...

* DESCRIPTION

   Rcsdiff runs diff(1) to compare two revisions of each RCS file given.  A
   file name ending in `,v' is an RCS file name, otherwise a working file name.
   Rcsdiff derives the working file name from the RCS file name and vice versa,
   as explained in rcsintro(1).  Pairs consisting of both an RCS and a working
   file name may also be specified.

   The options -b, -c, -e, -f, and -h have the same effect as described in
   diff(1); option -n generates an edit script of the format used by RCS.

   If both rev1 and rev2 are omitted, rcsdiff compares the latest revision on
   the trunk with the contents of the corresponding working file.  This is
   useful for determining what you changed since the last check in.

   If rev1 is given, but rev2 is omitted, rcsdiff compares revision rev1 of the
   RCS file with the contents of the corresponding working file.

   If both rev1 and rev2 are given, rcsdiff compares revisions rev1 and rev2 of
   the RCS file.

   Both rev1 and rev2 may be given numerically or symbolically.

* EXAMPLES

   The command:

      rcsdiff  f.c

   - runs diff on the latest trunk revision of RCS file f.c,v and the contents
   of working file f.c.
