Relevant standards for public-inbox users and hackers
-----------------------------------------------------

Non-exhaustive list of standards public-inbox software attempts or
intends to implement.  This list is intended to be a quick reference
for hackers and users.

Given the goals of interoperability and accessibility; strict
conformance to standards is not always possible, but rather
best-effort taking into account real-world cases.  In particular,
"obsolete" standards remain relevant as long as clients and
data exists.
