WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING

This is a dirty hack to emulate just so much of the libmodplug c++
interface so that the current known users (mainly xmms-modplug itself,
gstreamer modplug, audacious, and stuff based on those) work. This is
neither a complete nor a correct implementation.
Metadata and other state is not provided or updated.
