@ <ol>
@ <li> Blank lines are paragraph breaks
@ <li> Bullets are "*" surrounded by two spaces at the beginning of the line.
@ <li> Enumeration items are a number surrounded by two space
@ at the beginning of a line.
@ <li> Indented pargraphs begin with a tab or two spaces.
@ <li> Hyperlinks are contained with square brackets: "[target]"
@ <li> Most ordinary HTML works.
@ <li> <verbatim> and <nowiki>.
@ </ol>
@ <p>We call the first five rules above "wiki" formatting rules. The
@ last two rules are the HTML formatting rule.</p>
@ <h2>Formatting Rule Details</h2>
@ <ol>
@ <li> <p><b>Paragraphs</b>. Any sequence of one or more blank lines forms
@ a paragraph break. Centered or right-justified paragraphs are not
@ supported by wiki markup, but you can do these things if you need them
@ using HTML.</p>
@ <li> <p><b>Bullet Lists</b>.
@ A bullet list item are lines that begin with a single "*" character
@ surrounded on
@ both sides by two or more spaces or by a tab. Only a single level
@ of bullet list is supported by wiki. For nested lists, use HTML.</p>
@ <li> <p><b>Enumeration Lists</b>.
@ An enumeration list items are lines that begin
@ with one or more digits optionally
@ followed by a "." and surrounded on both sides by two or more spaces or
@ by a tab. The number is significant and becomes the number shown
@ in the rendered enumeration item. Only a single level of enumeration
@ list is supported by wiki. For nested enumerations or for
@ enumerations that count using letters or roman numerials, use HTML.</p>
@ <li> <p><b>Indented Paragraphs</b>.
@ Any paragraph that begins with two or more spaces or a tab and
@ which is not a bullet or enumeration list item is rendered
@ indented. Only a single level of indentation is supported by</p>
@ <li> <p><b>Hyperlinks</b>.
@ Text within square brackets ("[...]") becomes a hyperlink. The
@ target can be a wiki page name, the UUID of a check-in or ticket,
@ the name of an image, or a URL. By default, the target is displayed
@ as the text of the hyperlink. But you can specify alternative text
@ after the target name separated by a "|" character.</p>
@ <li> <p><b>HTML</b>.
@ The following standard HTML elements may be used:
@ <a>
@ <address>
@ <b>
@ <big>
@ <blockquote>
@ <br>
@ <center>
@ <cite>
@ <code>
@ <dd>
