+      GNU libtool is a generic library support script.  Libtool hides
+      the complexity of using shared libraries behind a consistent,
+      portable interface.
+
+      To use libtool, add the new generic library building commands to
+      your Makefile, Makefile.in, or Makefile.am.  See the
+      documentation for details.
