45 # Detect the exit code produced when our particular flavor of unzip
46 # sees an empty archive. Infozip will generate a warning and exit with
47 # code 1. But in the name of sanity, we do not expect other unzip
48 # implementations to do the same thing (it would be perfectly
49 # reasonable to exit 0, for example).
50 #
51 # This makes our test less rigorous on some platforms (unzip may not
52 # handle the empty repo at all, making our later check of its exit code
53 # a no-op). But we cannot do anything reasonable except skip the test
54 # on such platforms anyway, and this is the moral equivalent.
