<H2><A NAME="sec:8.3"><SPAN class="sec-nr">8.3</SPAN> <SPAN class="sec-title">The 
`Defaults' file</SPAN></A></H2>

<P>The <CODE>Defaults</CODE> file consists of statements. Each statement 
is on a separate line. A statement may be split over several lines by 
preceeding the newline with a backslash (<CODE>\</CODE>). The 
exclamation mark (<CODE>!</CODE>) is the line-comment character. All 
input from the <CODE>!</CODE> upto the following newline is replaced by 
a single space-character. Empty lines or lines containing only blank 
space are ignored.

<P>Default files may include other default files using the statement
<BLOCKQUOTE>
<TT>#include</TT> &lt;<VAR>file</VAR>&gt;
</BLOCKQUOTE>

<P>Default statements are of the form:
<BLOCKQUOTE>
&lt;<VAR>class</VAR>&gt;.&lt;<VAR>class-variable</VAR>&gt;: &lt;<VAR>value</VAR>&gt;
</BLOCKQUOTE>

<P>Where &lt;<VAR>class</VAR>&gt; denotes the name of the class, or <CODE>*</CODE> 
to indicate the default applies for any class defining this 
class-variable. If both forms are found, the statement with the explicit 
class-name is used.
&lt;<VAR>class-variable</VAR>&gt; denotes the class-variable name. &lt;<VAR>value</VAR>&gt; 
is the default value of the class-variable. The syntax for &lt;<VAR>value</VAR>&gt; 
is similar to the arguments of <A NAME="idx:send212:269"></A><A class="pred" href="sec-7.1.html#send/[2-12]">send/[2-12]</A>. 
The (informal) syntax for &lt;<VAR>value</VAR>&gt; is below.
