About the Tests
---------------

The following tests are from the original version, updated simply for speed
and rewritten to fit the new framework of the program.  These tests will
mainly catch memory errors due to bad bits which are permanently stuck high
or low:
  Random value
  XOR comparison
  SUB comparison
  MUL comparison
  DIV comparison
  OR comparison
  AND comparison
  
The following tests were implemented by me, and will do a slightly better job
of catching flaky bits, which may or may not hold a true value:
  Sequential Increment
  Block Sequential
  Solid Bits

The remaining tests were also implemented by me, and are designed to catch
bad bits which are dependent on the current values of surrounding bits in either
the same word32, or in the preceding and succeeding word32s.
  Bit Flip
  Checkerboard
  Walking Ones
  Walking Zeroes
  Bit Spread

There is also a test (Stuck Address) which is run first.  It determines if the 
memory locations the program attempts to access are addressed properly or not.  
If this test reports errors, there is almost certainly a problem somewhere in 
the memory subsystem.  Results from the rest of the tests cannot be considered 
accurate if this test fails:
  Stuck Address

Usage information is summarized in the file ABOUT, and in the man page.
