   2         IncludeUrlContentWiki macro for MoinMoin 1.3
   3         
   4         Get the content from an URL, process it as wiki markup, and return those
   5         formatted results. 
   6         
   7         I personally use this in cases where I have a web server
   8         process to dynamically generate content that relies on wiki
   9         features like macros, smileys, table layout rules, etc.
  10         
  11         Usage: [[IncludeUrlContentWiki( http://foo.com/wikimarkup )]]
