  23 Invoke bin/repeat-junit.sh from the root of a Voldemort
  24 checkout. bin/repeat-junit.sh invokes 'ant junit' num_times.
  25
  26 The argument num_times must be an integer.
  27
  28 The pretty html junit output that ends up in dist/junit-reports on a
  29 single invocation of 'ant junit' is collected in a temp
  30 directory. This circumvents the normal behavior of ant in which
  31 dist/junit-reports is overwritten with each invocation of 'ant
  32 junit'.
  33
  34 bin/repeat-junit.sh is useful to run after making some substantial
  35 changes, or when trying to track down intermittent failures (that
  36 occur more on your local box then on a Hudson test machine...).
