        HarfBuzz is an <ulink url="http://www.microsoft.com/typography/otspec/">OpenType</ulink>
        text shaping engine. Using the HarfBuzz library allows
	programs to convert a sequence of Unicode input into
	properly formatted and positioned glyph output&mdash;for any writing
	system and language.

    <note>
      <para>
        The current HarfBuzz codebase is versioned 2.x.x and is stable
	and under active maintenance. This is what is used in latest
	versions of Firefox, GNOME, ChromeOS, Chrome, LibreOffice,
	XeTeX, Android, and KDE, among other places. 
      </para>
      <para>
        Prior to 2012, the original HarfBuzz codebase (which, these
	days, is referred to as <emphasis>harfbuzz-old</emphasis>) was 
        derived from code in <ulink
	url="http://freetype.org/">FreeType</ulink>, <ulink
	url="http://pango.org/">Pango</ulink>, and 
        <ulink url="http://qt-project.org/">Qt</ulink>.
        It is <emphasis>not</emphasis> actively developed or
	maintained, and is extremely buggy. All users of harfbuzz-old
	are encouraged to switch over to the new HarfBuzz as soon as possible.
      </para>
      <para>
	To make this distinction clearer in discussions, the current
	HarfBuzz codebase is sometimes referred to as
	<emphasis>harfbuzz-ng</emphasis>.
      </para>
      <para>
	For reference purposes, the harfbuzz-old source tree is archived 
        <ulink
	    url="http://cgit.freedesktop.org/harfbuzz.old/">here</ulink>. There
	are no release tarballs of harfbuzz-old whatsoever.
