And then you'll need a parser, many of whose Unique Challenges™ aren't
even apparent until you start parsing files from actual users, and
you'll still need some sort of fallback in the code anyway for the case
that s_format can't be parsed (for whatever reason).

Isn't a config file what just caused the global CrowdStrike outage?  ;-)

That said, I understand that report generators are a thing, not to
mention RPG (https://en.wikipedia.org/wiki/IBM_RPG).

Okay, sorry; I'll just crawl back into the hole from whence I came.
