A wiki artifact defines a single version of a
single wiki page.
Wiki artifacts accept
the following card types:

<blockquote>
<b>C</b> <i>change-comment</i><br>
<b>D</b> <i>time-and-date-stamp</i><br />
<b>L</b> <i>wiki-title</i><br />
<b>N</b> <i>mimetype</i><br />
<b>P</b> <i>parent-artifact-id</i>+<br />
<b>U</b> <i>user-name</i><br />
<b>W</b> <i>size</i> <b>\n</b> <i>text</i> <b>\n</b><br />
<b>Z</b> <i>checksum</i>

the usual checksum over the entire artifact and is required.

The <b>W</b> card is used to specify the text of the wiki page.  The
argument to the <b>W</b> card is an integer which is the number of bytes
of text in the wiki page.  That text follows the newline character
that terminates the <b>W</b> card.  The wiki text is always followed by one
extra newline.

The <b>C</b> card on a wiki page is optional.  The argument is a comment
that explains why the changes was made.  The ability to have a <b>C</b>
card on a wiki page artifact was added on 2019-12-02 at the suggestion
of user George Krivov and is not currently used or generated by the 
implementation. Older versions of Fossil will reject a wiki-page
artifact that includes a <b>C</b> card.

An example wiki artifact can be seen
[/artifact?name=7b2f5fd0e0&txt=1 | here].
