Changes from 0.2.1 to 0.3.0
===========================
	* Use of libext2fs.
	* Use of autotools.
	* Almost full rewrite. This version has been pending for quite some
	  months...  I only added the use of libext2fs recently, and didn't
	  change a lot the old new stuff. It may be changed at some time in
	  the future.
