The Unionfs utils package includes:
	- user level utils : unionctl, unionimap and uniondbg
	- shared library : libunionfs_utils

To build and install Unionfs utils :
	- First run ./bootstrap
	- Then run ./configure
	- Finally run 'make' to build, or 'make install' to install

Install copies the user level utils to /usr/local/bin, the shared
library binaries to /user/local/bin, unionfs.h to /usr/local/include
and all man pages to /user/local/man

To specify a different install directory, before running 'make install',
run the configure script as follows:
	./configure --prefix=installdir
