**         the propagation of the tag to any descendants.  Use the
**         the --dryrun or -n options to see what would have happened.
**         the -n|--dryrun option to see what would have happened.

** > fossil tag find ?OPTIONS? TAGNAME
**
**         List all objects that use TAGNAME.  TYPE can be "ci" for
**         check-ins or "e" for events. The limit option limits the number
**         of results to the given value.

**
** Reparenting is accomplished by adding a parent tag.  So to undo the
** reparenting operation, simply delete the tag.
**
**    --test           Make database entries but do not add the tag artifact.
**                     So the reparent operation will be undone by the next
**                     "fossil rebuild" command.
**    --dryrun | -n    Print the tag that would have been created but do not
**    -n|--dryrun      Print the tag that would have been created but do not
**                     actually change the database in any way.
**    --date-override DATETIME  Set the change time on the control artifact
**    --user-override USER      Set the user name on the control artifact
