//! Doesn't seem like there's a cargo way of packaging cdylibs.
//! So instead we put a binary representation in the static lib and create it ad hoc on first use.
//! Unfortunately, there's no way to uninstall the dll's with cargo uninstall directly.
//! TODO: Sorry for all this. As soon as there's a built in way it'll be changed.
