--   Configurable Knuth-Liang hyphenation
--   
--   Uses the UTF8 encoded hyphenation patterns provided by hyph-utf8 from
--   <a>http://www.ctan.org/tex-archive/language/hyph-utf8</a>
--   
--   Usage:
--   
--   <pre>
--   &gt;&gt;&gt; hyphenate english_US "supercalifragilisticexpialadocious"
--   ["su","per","cal","ifrag","ilis","tic","ex","pi","al","ado","cious"]
--   </pre>
--   
--   <pre>
--   &gt;&gt;&gt; hyphenate english_US "hyphenation"
--   ["hy","phen","ation"]
--   </pre>
--   
--   <pre>
--   &gt;&gt;&gt; hyphenate icelandic "va\240lahei\240avegavinnuverkf\230rageymslusk\250r"

--   depending on whether or not they are even (no hyphen) or odd (hyphen
--   allowed).</li>
--   </ol>
--   
--   Patterns are overlaid and the maximum value at each location is used.
--   this allows you to implement a finite number of precedences between
--   hyphenation rules
--   
--   (e.g. <tt>3foo.</tt> indicates that the suffix '-foo' should be
--   hyphenated with precedence 3.)
