 {{{
 Local-Admins-MacBook-Pro:~ root# port -v livecheck doxygen
 doxygen seems to have been updated (port version: 1.8.3.1, new version:
 1.8.4)
 }}}
 Changelog link: http://www.stack.nl/~dimitri/doxygen/manual/changelog.html

 New features of note, that I felt like cherrypicking from the changelog
 linked above:

 - "clang-assisted parsing" - enabled with the `--with-libclang` option (we
 might want to make this a variant;
 [https://github.com/mxcl/homebrew/blob/master/Library/Formula/doxygen.rb#L13
 that's what Homebrew does at least])
 - docbook output support (not sure if this requires a new dependency on
 any of the docbook ports...)
 - support for documenting UNO packages (the type that OpenOffice uses)
 - can time itself when running
