+# This slightly ridiculous script gets OpenDCP to generate
+# a DCP using out test reference data (in j2c/ and wav/)
+# and then adjusts its XML output to account for the fact
+# that OpenDCP will generate its own random UUIDs (and use
+# current timestamps). We set UUIDs and timestamps back
+# to what our test suite will expect.
+#
+# The output of this script is checked into git, so
+# there's normally no need to run it.
+#
+# If you do run it, the XML should be right but the
+# MXFs that OpenDCP generates will not be quite what
+# we expect, as they also contain random UUIDs. I don't
+# think there's an easy way round that, so after running
+# this script you will need to check that the libdcp
+# test code generates correct MXFs (by verification on
+# a projector, probably), and then copy those MXFs into the
+# test/ref/DCP directory.
