+dnl
+dnl Enable a specific directory layout for the installation to use.
+dnl This configures a command-line parameter that can be specified
+dnl at ./configure invocation.
+dnl
+dnl The use of this feature in this way is a little hackish, but
+dnl better than a heap of options for every directory.
+dnl
+dnl This code is heavily borrowed *cough* from the Apache 2 code.
