cvs rtag command tags the repository as of a
certain date or time (or can be used to tag the latest
rtag works directly on the
repository contents (it requires no prior checkout and
does not look for a working directory).
The following options specify which date or revision to tag. See Common options, for a complete description of them.
Tag the most recent revision no later than date.
Only useful with the ‘-D date’ or ‘-r tag’ flags. If no matching revision is found, use the most recent revision (instead of ignoring the file).
Only tag those files that contain existing tag tag.
cvs tag command also allows one to specify
files by revision or date, using the same ‘-r’,
‘-D’, and ‘-f’ options. However, this
feature is probably not what you want. The reason is
cvs tag chooses which files to tag based on
the files that exist in the working directory, rather
than the files which existed as of the given tag/date.
Therefore, you are generally better off using
rtag. The exceptions might be cases like:
cvs tag -r 1.4 backend.c
