Fossil

**
**     %fossil tag cancel ?--raw? TAGNAME CHECK-IN
**
**         Remove the tag TAGNAME from CHECK-IN, and also remove
**         the propagation of the tag to any descendants.  Use the
**         the --dryrun or -n options to see what would have happened.
**
**         Options:
**           --raw                       Raw tag name.
**           --date-override DATETIME    Set date and time deleted.
**           --user-override USER        Name USER when deleting the tag.
**           --dryrun|-n                 Display the control artifact, but do
**                                       not insert it into the database.
**
**     %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.
**
**         Options:

**   fossil update tag:decaf
**
** will assume that "decaf" is a tag/branch name.
