Go up to tag.

tag options
-----------

   These standard options are supported by `tag' (*note Common
options::., for a complete description of them):

`-F'
     Overwrite an existing tag of the same name on a different revision.

`-l'
     Local; run only in current working directory.

`-R'
     Tag directories recursively.  This is on by default.

   Two special options are available:

`-b'
     The -b option makes the tag a branch tag (*note Revisions and
     branches::.), allowing concurrent, isolated development.  This is
     most useful for creating a patch to a previously released software
     distribution.

`-c'
     The -c option checks that all files which are to be tagged are
     unmodified.  This can be used to make sure that you can
     reconstruct the current file contents.

`-d'
     Delete a tag.

     If you use `cvs tag -d symbolic_tag', the symbolic tag you specify
     is deleted instead of being added.  Warning: Be very certain of
     your ground before you delete a tag; doing this permanently
     discards some historical information, which may later turn out to
     be valuable.
