19 * 93/10/31 - Added the -c option to change the maximal mount counts
20 * 93/12/14 - Added -l flag to list contents of superblock
21 * M.J.E. Mol (marcel@duteca.et.tudelft.nl)
22 * F.W. ten Wolde (franky@duteca.et.tudelft.nl)
23 * 93/12/29 - Added the -e option to change errors behavior
24 * 94/02/27 - Ported to use the ext2fs library
25 * 94/03/06 - Added the checks interval from Uwe Ohse (uwe@tirka.gun.de)
