Common-Description:
 Fontconfig is a library for configuring and customizing font access.
 .
 Fontconfig can:
 .
   * discover new fonts when installed automatically, removing a common source
     of configuration problems.
   * perform font name substitution, so that appropriate alternative fonts can
     be selected if fonts are missing.
   * identify the set of fonts required to completely cover a set of languages.
   * have GUI configuration tools built as it uses an XML-based configuration
     file (though with autodiscovery, we believe this need is minimized).
   * efficiently and quickly find the fonts you need among the set of fonts you
     have installed, even if you have installed thousands of fonts, while
     minimzing memory usage.
   * be used in concert with the X Render Extension and FreeType to implement
     high quality, anti-aliased and subpixel rendered text on a display.
 .
 Fontconfig does not:
 .
   * render the fonts themselves (this is left to FreeType or other rendering
     mechanisms)
   * depend on the X Window System in any fashion, so that printer only
     applications do not have such dependencies
