As mentioned in the README, this is derived from code for the Remit
(https://remit.scripts.mit.edu/trac/) and the ASA DB
(https://asa.scripts.mit.edu/trac/). If you see bug numbers in the history,
they're probably from Remit (https://remit.scripts.mit.edu/trac/query).
Hopefully these can be useful to somebody else.
