apparently simfactory requires me to do:
sim --mdbkey=optionlist my-very-own-option-list --thornlist=einsteintoolkit.th to overwrite mdb entries from the command line (and --define --substitue --replace --append --mdbkey). I have to admit I would not have guessed that from the help text which states:
options: -h, --help show this help message and exit --define=DEFINE set additional definition --mdbkey=MDBKEY override an mdb key
I would like to suggest to either change the help text to
--mdbkey=MDBKEY MDBVALUE or to support something like
--mdbkey="MDBKEY=VALUE" with or without quotation marks instead maybe.
Is there a full documented list of valid mdb entries somewhere?
