/*
** COMMAND: tag
**
** Usage: %fossil tag SUBCOMMAND ...
**
** Run various subcommands to control tags and properties.
**
** > fossil tag add ?OPTIONS? TAGNAME ARTIFACT-ID ?VALUE?
**
**         Add a new tag or property to an artifact referenced by
**         ARTIFACT-ID. For checkins, the tag will be usable instead
**         of a CHECK-IN in commands such as update and merge. If the
**         --propagate flag is present and ARTIFACT-ID refers to a
**         wiki page, forum post, technote, or check-in, the tag
**         propagates to all descendants of that artifact.
**

**         The --date-override and --user-override options support
**         importing history from other SCM systems. DATETIME has
**         the form 'YYYY-MMM-DD HH:MM:SS'.
**
**         Note that fossil uses some tag prefixes internally and this
**         command will reject tags with these prefixes to avoid
**         causing problems or confusion: "wiki-", "tkt-", "event-".
**
** > fossil tag cancel ?--raw? TAGNAME ARTIFACT-ID
**
**         Remove the tag TAGNAME from the artifact referenced by
**         ARTIFACT-ID, and also remove the propagation of the tag to
**         any descendants.  Use the the -n|--dry-run option to see
**         what would have happened. Certain tag name prefixes are
**         forbidden, as documented for the 'add' subcommand.
**
**         Options:
**           --raw                       Raw tag name. Ignored for
**                                       non-CHECK-IN artifacts.
**           --date-override DATETIME    Set date and time deleted.
**           --user-override USER        Name USER when deleting the tag.
**           -n|--dry-run                Display the control artifact, but do
**                                       not insert it into the database.
**
** > fossil tag find ?OPTIONS? TAGNAME
**
**         List all objects that use TAGNAME.
**
**         Options:
**           --raw           Interprets tag as a raw name instead of a
**                           branch name and matches any type of artifact.
**                           Changes the output to include only the
**                           hashes of matching objects.
**           -t|--type TYPE  One of: ci (check-in), w (wiki),
**                           e (event/technote), f (forum post),
**                           t (ticket). Default is all types. Ignored
**                           if --raw is used.
**           -n|--limit N    Limit to N results.
**
** > fossil tag list|ls ?OPTIONS? ?ARTIFACT-ID?
**
**         List all tags or, if ARTIFACT-ID is supplied, all tags and
**         their values for that artifact. The tagtype option accepts
**         one of: propagated, singleton, cancel.  For historical
**         scripting compatibility, the internal tag types "wiki-",
**         "tkt-", and "event-" (technote) are elided by default
**         unless the --raw or --prefix options are used.
**

** This is an experts-only command.  It is used to patch up a repository
** that has been damaged by a shun or that has been pieced together from
** two or more separate repositories.  You should never need to reparent
** during normal operations.
**
** 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.
**    -n|--dry-run     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
