Formatting

ToDo settle with some formatting and explain it here

Space with more than one line creates a new paragraph.

There are two ways to specify a markup command:

1. TeX or RTF like escaping:

   \\ outputs \

   \< outputs <

   \~ outputs non-breakable space like the HTML &nbsp; entity

   \== outputs a horizontal line like the HTML tag <hr>

   ---

   \{http://logand.com Logand} outputs an external link Logand

   \{Sandbox} outputs an internal link Sandbox

2. XML like escaping:

   <b>text</b> outputs the text in bold

   <u>text</u> outputs the text underlined

   <h2>heading 2</h2> or <h3>heading 3</h3> outputs a heading

   heading 2

   heading 3

   <ul><li>1st</li><li>2nd</li></ul> outputs a bulleted list

   • 1st
   • 2nd

   <ol><li>1st</li><li>2nd</li></ol> outputs a numbered list

   1. 1st
   2. 2nd

   <table>
   <tr><td>a1</td><td>a2</td></tr>
   <tr><td>b1</td><td>b2</td></tr>
   </table>

   outputs a table

   a1	a2
   b1	b2

   <pre>...</pre> preserves whitespace until the enclosing < character is encountered

   if [ "$USER" != "root" ]; then
       PATH=$HOME/bin:$PATH
   else
       PATH=/etc:/usr/etc:$PATH
   fi
   

   <lisp>some code</lisp> is like <pre> but expects the content to be picolisp code and creates cross reference links for built in functions

   (println *OS)
   (de _markupXml (End)
      (char)
      (let? C (till ">" T)
         (char)
         (unless (= C End)
            (cons C (_markup (pack "/" C))))))
   

ToDo not sure whether to keep both TeX like and XML like formatting?

ToDo what other markup would be useful?
