/* Wrappedtext -wrappedtext.php-

  If a site uses narrow tables this is a great tool because words that are
  longer as the width of a table would enlarge the table and deface the site
  layout. using php's wordwrap function has the disadvantage that the whole
  text is wrapped which means that short words might also get cut at a certain
  position of the line. in addition wordwrap can't be used if the text that
  needs to be wrapped contains html tags.
