Fossil

**         --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.
**
**         Options:
**           --raw                      Raw tag name. Ignored for
**                                      non-CHECK-IN artifacts.
**           --propagate                Propagating tag.
**           --date-override DATETIME   Set date and time added.
**           --user-override USER       Name USER when adding the tag.
**           -n|--dry-run               Display the tag text, but do not
**                                      actually insert it into the database.
**
**         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.
**
**         Options:
**           --raw           List raw names of tags
**           --tagtype TYPE  List only tags of type TYPE, which must
**                           be one of: cancel, singleton, propagated
**           -v|--inverse    Inverse the meaning of --tagtype TYPE.
**           --prefix        List only tags with the given prefix.
**                           Fossil-internal prefixes include "sym-"
**                           (branch name), "wiki-", "event-"
**                           (technote), and "tkt-" (ticket). The
**                           prefix is stripped from the resulting
**                           list unless --raw is provided. Ignored if
**                           ARTIFACT-ID is provided.
