** COMMAND: wiki*
**
** Usage: %fossil wiki (export|create|commit|list) WikiName
**
** Run various subcommands to work with wiki entries or tech notes.
**
**    %fossil wiki export PAGENAME ?--? ?FILE?
**    %fossil wiki export -t|--technote DATETIME|TECHNOTE-ID ?--? ?FILE?
**
**       Sends the latest version of either a wiki page or of a tech note
**       to the given file or standard output.
**       If PAGENAME is provided, the wiki page will be output. For
**       a tech note either DATETIME or TECHNOTE-ID must be specified. If
**       DATETIME is used, the most recently modified tech note with that
**       DATETIME will be sent.

**
** 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:
**   --                      For commands which support this, it means to treat
**                           all subsequent arguments as file names even if they
**                           start with a "-".
