%description
In the early days, aufs was entirely re-designed and re-implemented
Unionfs. After many original ideas, approaches, improvements and
implementations, it becomes totally different from Unionfs while
keeping the basic features. Unionfs is being developed by Professor
Erez Zadok at Stony Brook University and his team. If you don't know
Unionfs, I recommend you to try and know it before using aufs. Some
terminology in aufs follows Unionfs's.
