+       Actually, the PREFIX, no matter where you specify it, is only
+       intended to control where files are _installed_, not where they're
+       looked for at runtime.
+
+       There's a good reason not to make PREFIX be used to actually
+       change the program's behavior: Most packaging systems use PREFIX
+       when building the package, to make it install into a temporary
+       directory which gets packaged up.
+
+       It would probably be nice if ikiwiki offered a separate build-time
+       setting to control where it looked for its data files, though it already
+       offers a way to do it at runtime (--underlaydir and --templatedir).
