+@cindex include_dir directive
+Additionally, a directory containing configuration snippets can be 
+processed using an @i{include_dir directive}. This directive has the 
+effect of inlining the contents of the files contained in the named
+directory at the point of inclusion.
+The files are ordered lexicographically and ``hidden`` files (those
+having a name beginning with a dot) are excluded.
+
+An include_dir directive must appear on its own line in the input:
+
+@b{@@include_dir "}@i{dirname}@b{"}
+
+The same quoting rules as for @i{@@include} apply.

 Include files may be nested to a maximum of 10 levels; exceeding this
 limit results in a parse error.
