  16 # This script generates 6856 tests for the set(1) and read(1)
  17 # builtins w.r.t. IFS whitespace and non-whitespace characters.
  18 # Each failed test produces one line on the standard output that
  19 # contains the test along with the expected and actual results.
  20 # The last output line contains the test result counts.  ordered>0
  21 # are the number of tests where IFS=": " produced different results
  22 # than IFS=" :".  If a test fails the same way for IFS=": " and
  23 # IFS=" :" then the second output line is suppressed.
