    <title>Introduction to Graphite2</title>

    <para>
      <application>Graphite2</application> is a rendering engine for graphite
      fonts. These are TrueType fonts with additional tables containing smart
      rendering information and were originally developed to support complex
      non-Roman writing systems.  They may contain rules for e.g. ligatures,
      glyph substitution, kerning, justification - this can make them useful
      even on text written in Roman writing systems such as English.  Note that
      <application>firefox</application> provides an internal copy of the
      graphite engine and cannot use a system version, but it too should benefit
      from the availability of graphite fonts.
