A range consisting of a branch number means the latest revision on that branch. None of the outdated revisions can have branches or locks.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 file pathname cannot begin with - . Preserve the modification time on the RCS file unless a revision is removed. Print RCS's version number. At least one explicit option must be given, to ensure compa- tibility with future planned extensions to the rcs command.
