+
+/*
+ * 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).
