# Checks email-gravatar.lua and email-libravatar.lua, the shipped email
# filters, which differ only in the service the icon is fetched from. The
# unit checks run each under every suitable standalone Lua with a
# deterministic digest standing in for luaossl, with the module made to
# fail to load, and once more against the real module wherever it is
# installed, which adds the check that a known address hashes to its SHA-256.
# Through cgit itself the icon is checked wherever a probe finds luaossl in
# the binary's own Lua, and the fallback with every Lua module kept off the
# search path, which gives it on any machine.
