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