-  This program opens files in progression (file00001, file00002 etc),
-  upto MAX_NUM_FILES and checks their CRC. If a file is not found or the
-  CRC does not match it stops it's operation.
-
-  Everything is logged in a logfile called './logfile'.
-
-  If everything is ok this program sends a signal, via com1, to the remote
-  power control box to power cycle this computer.
-
-  This program then proceeds to create new files file0....file<MAX_NUM_FILES>
-  in a endless loop and checksum each before closing them.
-
-  STRUCTURE OF THE FILES:
-  The fist int is the size of the file in bytes.
-  The last 2 bytes are the CRC for the entire file.
-  There is random data in between.
-
-  The files are opened in the current dir.

-  Revision 1.8  2005/11/07 11:15:17  gleixner
-  [MTD / JFFS2] Clean up trailing white spaces
-
-  Revision 1.7  2001/06/21 23:04:17  dwmw2
-  Initial import to MTD CVS
-
-  Revision 1.6  2001/06/08 22:26:05  vipin
-  Split the modbus comm part of the program (that sends the ok to pwr me down
-  message) into another file "comm.c"
-
-  Revision 1.5  2001/06/08 21:29:56  vipin
-  fixed small issue with write() checking for < 0 instead of < (bytes to be written).
-  Now it does the latter (as it should).
-
-  Revision 1.4  2001/05/11 22:29:40  vipin
-  Added a test to check and err out if the first int in file (which tells us
-  how many bytes there are in the file) is zero. This will prevent a corrupt
-  file with zero's in it from passing the crc test.
-
-  Revision 1.3  2001/05/11 21:33:54  vipin
-  Changed to use write() rather than fwrite() when creating new file. Additionally,
-  and more important, it now does a single write() for the entire data. This will
-  enable us to use this program to test for power fail *data* reliability when
-  writing over an existing file, specially on powr fail "safe" file systems as
-  jffs/jffs2. Also added a new cmdline parameter "-e" that specifies the max # of
-  errors that can be tolerated. This should be set to ZERO to test for the above,
-  as old data should be reliabily maintained if the newer write never "took" before
-  power failed. If the write did succeed, then the newer data will have its own
-  CRC in place when it gets checked => hence no error. In theory at least!
-
-
-  Revision 1.2  2001/05/11 19:27:33  vipin
-  Added cmd line args to change serial port, and specify max size of
-  random files created. Some cleanup. Added -Wall to Makefile.
-
-  Revision 1.1  2001/05/11 16:06:28  vipin
-  Importing checkfs (the power fail test program) into CVS. This was
-  originally done for NEWS. NEWS had a lot of version, this is
-  based off the last one done for NEWS. The "makefiles" program
-  is run once initially to create the files in the current dir.
-  "checkfs" is then run on every powerup to check consistancy
-  of the files. See checkfs.c for more details.
