   2 #
   3 # Tests for the effective RunFlags of a shell command (run/skip, echo/silent,
   4 # error check, trace), which are controlled by 12 different switches.  These
   5 # switches interact in various non-obvious ways.  To analyze the interactions,
   6 # this test runs each possible combination of these switches, for now.
   7 #
   8 # As soon as an interaction of switches is identified as obvious and expected,
   9 # this particular interaction may be removed from the test, to focus on the
  10 # remaining ones.
