It moves all the content from /lib and /bin to /usr/lib and /usr/bin
respectively and then makes /lib and /bin symlinks.  The wiki page
actually tells you this.

Also, this is Open Source software, not magic.  You can always read
the code, which is ultimately the best documentation if you want to
know _exactly_ what it does.
