   <H3><A name=sectc5221a>The <TT>Indent</TT> rule</A></H3>
   
   <P>
   The <TT>Indent</TT> rule is used to modify the value of text indentation
   in the output files.</P>
   <P>
   Each time the translator creates a new line in an output file, it generates
   a variable number of space characters at the beginning of the new line.  By
   default, the number of these characters (the indentation) is 0.  It can be
   changed with the <TT>Indent</TT> rule.</P>
   <P>
   The rule begins with the <TT>Indent</TT> keyword, followed by the indentation
   sign (optional) and value and a keyword <TT>Before</TT> or <TT>After</TT>
   indicating that the indentation should be changed <A href="#sectc5222">before
   or after</A> the element's content is generated.  If the position is not
   indicated, the indentation is changed before the element's content is
   generated.  This rule, like all translation rules, is terminated by a
   semicolon.</P>
   <P>
   The indentation value is indicated by an integer, which is the number of
   space characters to be generated at the beginning of each new line.
   A sign (<TT>+</TT> or <TT>-</TT>) can appear before the integer to indicate
   that the value is relative: the current value of indentation is incremented
   (if sign is <TT>+</TT>) or decremented (if sign is <TT>-</TT>) by the
   specified value.
   <P>
   Like the <A href="#sectc5210"><TT>Create</TT> rule</A>, the <TT>Indent</TT>
   keyword can be followed by the <TT>IN</TT> keyword and by the name of a
   <A href="#sectc526">variable</A>.  This means that the rule must not change
   indentation in the main output file, but in the file whose name is specified
   by the variable (by default, indentation is changed in the main output
   file).</P>
