<refpurpose>Maximum length of extra3 in header/footer</refpurpose>
<src:fragment xml:id="">
<xsl:param name="">30</xsl:param>
<para>Specifies the maximum permitted length of the
<literal>extra3</literal> part of the man-page <literal>.TH</literal>
title line header/footer. If the <literal>extra3</literal> content
exceeds the maxiumum specified, it is truncated down to the maximum
permitted length.</para>
<para>The content of the <literal>extra3</literal> field is usually
displayed in the middle header of the page and is typically a "manual
name"; for example, "GTK+ User's Manual" (from the
<literal>gtk-options(7)</literal> man page).</para>
<para>The default value for this parameter is reasonable but somewhat
arbitrary. If you are processing pages with long "manual names" -- or
especially if you are processing pages that have both long "title"
parts (command/function, etc. names) <emphasis>and</emphasis> long
manual names -- you may want to experiment with changing the value in
order to achieve the correct aesthetic results.</para>
