+/*
+ * 09.11.91  -  made the first rudimentary functions
+ *
+ * 10.11.91  -  updated, does checking, no repairs yet.
+ *		Sent out to the mailing-list for testing.
+ *
+ * 14.11.91  -	Testing seems to have gone well. Added some
+ *		correction-code, and changed some functions.
+ *
+ * 15.11.91  -  More correction code. Hopefully it notices most
+ *		cases now, and tries to do something about them.
+ *
+ * 16.11.91  -  More corrections (thanks to Mika Jalava). Most
+ *		things seem to work now. Yeah, sure.
+ *
+ *
+ * 19.04.92  -	Had to start over again from this old version, as a
+ *		kernel bug ate my enhanced fsck in February.
+ *
+ * 28.02.93  -	added support for different directory entry sizes..
+ *
+ * Sat Mar  6 18:59:42 1993, faith@cs.unc.edu: Output namelen with
+ *                           super-block information
+ *
+ * Sat Oct  9 11:17:11 1993, faith@cs.unc.edu: make exit status conform
+ *                           to that required by fsutil
+ *
+ * Mon Jan  3 11:06:52 1994 - Dr. Wettstein (greg%wind.uucp@plains.nodak.edu)
+ *			      Added support for file system valid flag.  Also
+ *			      added program_version variable and output of
+ *			      program name and version number when program
+ *			      is executed.
+ *
+ * 30.10.94 - added support for v2 filesystem
+ *            (Andreas Schwab, schwab@issan.informatik.uni-dortmund.de)
+ *
+ * 10.12.94  -  added test to prevent checking of mounted fs adapted
+ *              from Theodore Ts'o's (tytso@athena.mit.edu) e2fsck
+ *              program.  (Daniel Quinlan, quinlan@yggdrasil.com)
+ *
+ * 01.07.96  - Fixed the v2 fs stuff to use the right #defines and such
+ *	       for modern libcs (janl@math.uio.no, Nicolai Langfeldt)
+ *
+ * 02.07.96  - Added C bit fiddling routines from rmk@ecs.soton.ac.uk
+ *             (Russell King).  He made them for ARM.  It would seem
+ *	       that the ARM is powerful enough to do this in C whereas
+ *             i386 and m64k must use assembly to get it fast >:-)
+ *	       This should make minix fsck systemindependent.
+ *	       (janl@math.uio.no, Nicolai Langfeldt)
+ *
+ * 04.11.96  - Added minor fixes from Andreas Schwab to avoid compiler
+ *             warnings.  Added mc68k bitops from
+ *	       Joerg Dorchain <dorchain@mpi-sb.mpg.de>.
+ *
+ * 06.11.96  - Added v2 code submitted by Joerg Dorchain, but written by
+ *             Andreas Schwab.
+ *
+ * 1999-02-22 Arkadiusz Miśkiewicz <misiek@pld.ORG.PL>
+ * - added Native Language Support
+ *
+ * 2008-04-06 James Youngman <jay@gnu.org>
+ * - Issue better error message if we fail to open the device.
+ * - Restore terminal state if we get a fatal signal.
+ *
+ *
+ * I've had no time to add comments - hopefully the function names
+ * are comments enough. As with all file system checkers, this assumes
+ * the file system is quiescent - don't use it on a mounted device
+ * unless you can be sure nobody is writing to it (and remember that the
+ * kernel can write to it when it searches for files).
