+# 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, and once more against the
+# real module wherever it is installed, which adds the check that a known
+# address hashes to its published md5. The run through cgit itself needs
+# luaossl inside the binary's own Lua, so it is probed for rather than
+# assumed.
