+tailored for including listings of computer program source code into
+documents.  The main advantages over the original @code{verbatim} environment
+are: environments automatically fixes leading whitespace so that the
+environment and program listing can be indented with the rest of the document
+source, and; @code{listing} environments may easily be customised and
+extended.")
