-/**
- *  Takes HTML and converts it to formatted, plain text.
- *
- *  Thanks to Alexander Krug (http://www.krugar.de/) to pointing out and
- *  correcting an error in the regexp search array. Fixed 7/30/03.
- *
- *  Updated set_html() function's file reading mechanism, 9/25/03.
- *
- *  Thanks to Joss Sanglier (http://www.dancingbear.co.uk/) for adding
- *  several more HTML entity codes to the $search and $replace arrays.
- *  Updated 11/7/03.
- *
- *  Thanks to Darius Kasperavicius (http://www.dar.dar.lt/) for
- *  suggesting the addition of $allowed_tags and its supporting function
- *  (which I slightly modified). Updated 3/12/04.
- *
- *  Thanks to Justin Dearing for pointing out that a replacement for the
- *  <TH> tag was missing, and suggesting an appropriate fix.
- *  Updated 8/25/04.
- *
- *  Thanks to Mathieu Collas (http://www.myefarm.com/) for finding a
- *  display/formatting bug in the _build_link_list() function: email
- *  readers would show the left bracket and number ("[1") as part of the
- *  rendered email address.
- *  Updated 12/16/04.
- *
- *  Thanks to Wojciech Bajon (http://histeria.pl/) for submitting code
- *  to handle relative links, which I hadn't considered. I modified his
- *  code a bit to handle normal HTTP links and MAILTO links. Also for
- *  suggesting three additional HTML entity codes to search for.
- *  Updated 03/02/05.
- *
- *  Thanks to Jacob Chandler for pointing out another link condition
- *  for the _build_link_list() function: "https".
- *  Updated 04/06/05.
- *
- *  Thanks to Marc Bertrand (http://www.dresdensky.com/) for
- *  suggesting a revision to the word wrapping functionality; if you
- *  specify a $width of 0 or less, word wrapping will be ignored.
- *  Updated 11/02/06.
- *
- *  *** Big housecleaning updates below:
- *
- *  Thanks to Colin Brown (http://www.sparkdriver.co.uk/) for
- *  suggesting the fix to handle </li> and blank lines (whitespace).
- *  Christian Basedau (http://www.movetheweb.de/) also suggested the
- *  blank lines fix.
- *
- *  Special thanks to Marcus Bointon (http://www.synchromedia.co.uk/),
- *  Christian Basedau, Norbert Laposa (http://ln5.co.uk/),
- *  Bas van de Weijer, and Marijn van Butselaar
- *  for pointing out my glaring error in the <th> handling. Marcus also
- *  supplied a host of fixes.
- *
- *  Thanks to Jeffrey Silverman (http://www.newtnotes.com/) for pointing
- *  out that extra spaces should be compressed--a problem addressed with
- *  Marcus Bointon's fixes but that I had not yet incorporated.
- *
- *  Thanks to Daniel Schledermann (http://www.typoconsult.dk/) for
- *  suggesting a valuable fix with <a> tag handling.
- *
- *  Thanks to Wojciech Bajon (again!) for suggesting fixes and additions,
- *  including the <a> tag handling that Daniel Schledermann pointed
- *  out but that I had not yet incorporated. I haven't (yet)
- *  incorporated all of Wojciech's changes, though I may at some
- *  future time.
- *
- *  *** End of the housecleaning updates. Updated 08/08/07.
