fuselagefs consists of a C++ wrapper class for
FUSE called Fuselagefs, as well as Delegatefs,
which is a Fuselagefs subclass that delegates all
operations to an underlying base filesystem. With
Delegatefs, you can expose dir1 at mountpoint dir2
very easily as a FUSE filesystem. Subclasses of
Delegatefs can then be created, which add a little
extra functionality to the delegation operation
but rely on the parent class to perform the work
and return errors to FUSE in an appropriate
manner. An example subclass is petardfs.
