<refsection><info><title>Description</title></info>

<para>Specifies with em units the width of a single character
of the monospace font. The default value is <literal>0.6em</literal>.</para>

<para>This parameter is only used when a <tag>screen</tag>
or <tag>programlisting</tag> element has a 
<tag class="attribute">width</tag> attribute, which is
expressed as a plain integer to indicate the maximum character count
of each line.
To convert this character count to an actual maximum width
measurement, the width of the font characters must be provided.
Different monospace fonts have different character width,
so this parameter should be adjusted to fit the 
monospace font being used.
