+Test notes:
+This test uses the script_valid and script_invalid tests from the unittest
+framework to do end-to-end testing where we compare that two nodes agree on
+whether blocks containing a given test script are valid.
+
+We generally ignore the script flags associated with each test (since we lack
+the precision to test each script using those flags in this framework), but
+for tests with SCRIPT_VERIFY_P2SH, we can use a block time after the BIP16
+switchover date to try to test with that flag enabled (and for tests without
+that flag, we use a block time before the switchover date).
+
+NOTE: This test is very slow and may take more than 40 minutes to run.
