+/*
+ * DD.MM.YY
+ *
+ * 24.11.91  -	Time began. Used the fsck sources to get started.
+ *
+ * 25.11.91  -	Corrected some bugs. Added support for ".badblocks"
+ *		The algorithm for ".badblocks" is a bit weird, but
+ *		it should work. Oh, well.
+ *
+ * 25.01.92  -	Added the -l option for getting the list of bad blocks
+ *		out of a named file. (Dave Rivers, rivers@ponds.uucp)
+ *
+ * 28.02.92  -	Added %-information when using -c.
+ *
+ * 28.02.93  -	Added support for other namelengths than the original
+ *		14 characters so that I can test the new kernel routines..
+ *
+ * 09.10.93  -	Make exit status conform to that required by fsutil
+ *		(Rik Faith, faith@cs.unc.edu)
+ *
+ * 31.10.93  -	Added inode request feature, for backup floppies: use
+ *		32 inodes, for a news partition use more.
+ *		(Scott Heavner, sdh@po.cwru.edu)
+ *
+ * 03.01.94  -	Added support for file system valid flag.
+ *		(Dr. Wettstein, greg%wind.uucp@plains.nodak.edu)
+ *
+ * 30.10.94 - added support for v2 filesystem
+ *	      (Andreas Schwab, schwab@issan.informatik.uni-dortmund.de)
+ * 
+ * 09.11.94  -	Added test to prevent overwrite of mounted fs adapted
+ *		from Theodore Ts'o's (tytso@athena.mit.edu) mke2fs
+ *		program.  (Daniel Quinlan, quinlan@yggdrasil.com)
+ *
+ * 03.20.95  -	Clear first 512 bytes of filesystem to make certain that
+ *		the filesystem is not misidentified as a MS-DOS FAT filesystem.
+ *		(Daniel Quinlan, quinlan@yggdrasil.com)
+ *
+ * 02.07.96  -  Added small patch from Russell King to make the program a
+ *		good deal more portable (janl@math.uio.no)
+ *
+ * Usage:  mkfs [-c | -l filename ] [-v] [-nXX] [-iXX] device [size-in-blocks]
+ *
+ *	-c for readablility checking (SLOW!)
+ *      -l for getting a list of bad blocks from a file.
+ *	-n for namelength (currently the kernel only uses 14 or 30)
+ *	-i for number of inodes
+ *	-v for v2 filesystem
+ *
+ * The device may be a block device or a image of one, but this isn't
+ * enforced (but it's not much fun on a character device :-).
