 # WARNING:
+# Running coverage tests with kdbx 3 seems to be too slow right now, so we only run kdbx 4 tests
+# (kdbx4 with argon2 runs on native code, so no code coverage is collected there, vs.
+# kdbx3's AES KDF runs in dart).
+#
 # This is way too slow. Probably because of cryptography with coverage colleciton.
