Please use the latest version if you can. The documentation should be  
supposed to apply to the latest version, also some bugs may have already  
been fixed.

Sorry, you need to have at least 2.2.58 to use $GLOBALS["MarkupToHTML"].  
I'll add it to the documentation.

But if you can, upgrade to the latest version and not to 2.2.58.

If your function doesn't use $pagename:

  Markup('name', 'where', 'pattern', 'functionName');
  function functionName($m) {  } # '$1' is now $m[1], no need for PSS()

If your function uses $pagename, either the above with the extract() line,  
or this:

  Markup_e('name', 'where', 'pattern', "functionName(\$pagename, \$m[1])");
