-This project implements a "fuse" device to mount as a single file that
-is a concatenation of fragments of one or more files. The fused file
-allows overwriting to fragments but not changing their sizes and only
-for writable fragment files. A fused file may also be set up with an
-overlay file in which case that file will capture all changes instead
-of changing the underlying fragment files.
