Aha. Unfortunately that won't work. FreeMarker itself has no problem
with classpath resources, but "by design" FMPP has, since it deals
with files directly, no VFS abstraction or like. This thing was
originally written to solve some dirty file preprocessing issues for
me, and that was the quick way... /-:

If it's really a big problem for you, you might consider using
FreeMarker directly. If you depend on many FMPP features, that could
be painful though.
