http://bugs.debian.org/486482
* debian/patches/add_manpage.diff: Modified the man page
  to recommend that "mk4ht" be used for conversions other than
  from TeX/LaTeX to HTML. This is in response to #495768.
* debian/control: Replaced "sun-java5-jre" with "openjdk-6-jre-headless"
  in the "Suggests" field for "tex4ht-common". The latter java runtime
  seems to work with "xtpipes.jar" and the former is non-free.
  (Closes: #486482)
