    <title>DESCRIPTION</title>

      <para><command>&dhpackage;</command> scans the font directories on
        the system and builds font information cache files for
        applications using fontconfig for their font handling.</para>

      <para>If directory arguments are not given,
        <command>&dhpackage;</command> uses each directory in the
        current font configuration. Each directory is scanned for
        font files readable by FreeType.  A cache is created which
        contains properties of each font and the associated filename.
        This cache is used to speed up application startup when using
        the fontconfig library.</para>

      <para>Note that <command>&dhpackage;</command> must be executed
        once per architecture to generate font information customized
        for that architecture.</para>
