        <para>
            Without any argument, <literal>xlfont()</literal> returns the list
            of currently loaded fonts.
        </para>
        <para>xlfont('AVAILABLE_FONTS') returns list of fonts available on your
            system.
        </para>
        <para>xlfont('reset') reset to initial index list of fonts.</para>
        <para>
            With arguments, <literal>xlfont</literal> is used to load a new font
            at different sizes in the graphics context.
        </para>
        <para>Default family fonts are "Monospaced" (0), "Symbol" (1), "Serif"
            (2), "Serif Italic" (3), "Serif Bold" (4), "Serif Bold Italic" (5),
            "SansSerif" (6), "SansSerif Italic" (7), "SansSerif Bold" (8), "SansSerif
            Bold Italic" (9). These default fonts are automatically loaded when needed
            and so <literal>xlfont</literal> is not really required for them. In fact
            <literal>xlfont</literal> is essentially useful to load a new font.
