** COMMAND: leaves*
**
** Usage: %fossil leaves ?OPTIONS?
**
** Find leaves of all branches.  By default show only open leaves.
** The -a|--all flag causes all leaves (closed and open) to be shown.
** The -c|--closed flag shows only closed leaves.
**
** The --recompute flag causes the content of the "leaf" table in the
** repository database to be recomputed.
**
** Options:
**   -a|--all         show ALL leaves
**   -c|--closed      show only closed leaves
**   --bybranch       order output by branch name
**   --recompute      recompute the "leaf" table in the repository DB
**   -W|--width <num> Width of lines (default is to auto-detect). Must be
**                    >39 or 0 (= no limit, resulting in a single line per
**                    entry).

**   --offset P           skip P changes
**   -p|--print           select print mode
