- * History:
- * 93/06/01	- Creation
- * 93/10/31	- Added the -c option to change the maximal mount counts
- * 93/12/14	- Added -l flag to list contents of superblock
- *                M.J.E. Mol (marcel@duteca.et.tudelft.nl)
- *                F.W. ten Wolde (franky@duteca.et.tudelft.nl)
- * 93/12/29	- Added the -e option to change errors behavior
- * 94/02/27	- Ported to use the ext2fs library
- * 94/03/06	- Added the checks interval from Uwe Ohse (uwe@tirka.gun.de)
