+# Definition of installation directories, we don't use half of these, but since
+# the configure script has them on offer while passing through, we might as well
+# set them. Note that we have to be careful, because the GNU coding standards
+# have changed a bit over the course of time, and autoconf development reflects
+# this.
+#
