** 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 ?FILE? -t|--technote DATETIME|TECHNOTE-ID
**
** 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.
**
** %fossil wiki (create|commit) PAGENAME ?FILE? ?OPTIONS?
**
** Create a new or commit changes to an existing wiki page or
** technote from FILE or from standard input. PAGENAME is the
** name of the wiki entry or the timeline comment of the
** technote.
**
** Options:
** -M|--mimetype TEXT-FORMAT The mime type of the update.
** Defaults to the type used by
** the previous version of the
** page, or text/x-fossil-wiki.
** Valid values are: text/x-fossil-wiki,
** text/markdown and text/plain. fossil,
** markdown or plain can be specified as
** synonyms of these values.
** -t|--technote DATETIME Specifies the timestamp of
** the technote to be created or
** updated. When updating a tech note
** the most recently modified tech note
** with the specified timestamp will be
** updated.
** -t|--technote TECHNOTE-ID Specifies the technote to be
** updated by its technote id.
** --technote-tags TAGS The set of tags for a technote.
** --technote-bgcolor COLOR The color used for the technote
** on the timeline.
**
** %fossil wiki list ?OPTIONS?
** %fossil wiki ls ?OPTIONS?
**
** Lists all wiki entries, one per line, ordered
** case-insensitively by name.
**
** Options:
** -t|--technote Technotes will be listed instead of
** pages. The technotes will be in order
** of timestamp with the most recent
** first.
** -s|--show-technote-ids The id of the tech note will be listed
** along side the timestamp. The tech note
** id will be the first word on each line.
** This option only applies if the
** --technote option is also specified.
**
** 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.
