A range consisting of a branch number means the latest revision on that branch. None of the outdated revisions may have branches or locks. Set the state attribute of the revision rev to state . If rev is a branch number, assume the latest revision on that branch. If rev is omitted, assume the latest revision on the default branch.
Any identifier is acceptable for state .
Write descriptive text from the contents of the named file into the RCS file, deleting the existing text. The -b rev option generates an RCS file that cannot be parsed by RCS version 3 or earlier. Use rcs -V n to make an RCS file acceptable to RCS version n by discarding information that would confuse version n . RCS version 5.5 and earlier does not support the -x option, and requires a ,v suffix on an RCS pathname. The RCS pathname and the revisions outdated are written to the diagnostic output.
