Footnotes

Footnotes make a document look professional. 6

Here are two macros that implement footnotes in PerlPoint:

    +FNR:\SUP<\F{size="-2"}<\REF{type=linked name="__n__"}>>
  
    +FN:\F{size="-2"}<\SEQ{type=footnotes name="__n__"}: __body__>

\FNR is used to set a footnote reference. It adds a small note number as a link to an anchor named by option n.

\FN makes this anchor, taking the same n parameter to name it, and its body as the note. By making te anchor via \SEQ we have an automatic counter increased with each usage of the macro.

And here is a usage example:

    Bla bla bla bla bla \FNR{n="bla"}
  
    Bla bla bla bla bla bla bla
  
    // footnotes
    \HR
  
    .\FN{n="bla"}<Typically, this stands for
       any text.>

By using the dotted form of a text paragraph for the note we allow the note text to be wrapped at any position. 7

6: Besides, they are just handy ;-)

7: Otherwise the explanation could not leave the first line without an parser error, as a tag starting a paragraph needs to be closed before the paragraph type can be determined.
