**
** before
** after
** descendants | children

**
** The CHECKIN can be any unique prefix of 4 characters or more. You
** can also say "current" for the current version.
**
** DATETIME may be "now" or "YYYY-MM-DDTHH:MM:SS.SSS". If in
** year-month-day form, it may be truncated, the "T" may be replaced by
** a space, and it may also name a timezone offset from UTC as "-HH:MM"
** (westward) or "+HH:MM" (eastward). Either no timezone suffix or "Z"
** means UTC.
**
**
** Options:
** -n|--limit N If N is positive, output the first N entries. If
** N is negative, output the first -N lines. If N is
** zero, no limit. Default is -20 meaning 20 lines.
** -p|--path PATH Output items affecting PATH only.
** PATH can be a file or a sub directory.
** --offset P skip P changes
** --sql Show the SQL used to generate the timeline
** -t|--type TYPE Output items from the given types only, such as:
** ci = file commits only
** e = technical notes only
** t = tickets only
** w = wiki commits only
** -v|--verbose Output the list of files changed by each commit
** and the type of each change (edited, deleted,
** etc.) after the check-in comment.
** -W|--width <num> Width of lines (default is to auto-detect). Must be
** >20 or 0 (= no limit, resulting in a single line per
** entry).
** -R REPO_FILE Specifies the repository db to use. Default is
** the current checkout's repository.
