+# With Apache 2.4 the "Order, Deny" syntax has been deprecated and moved from

+# disabled) and a new "Require" syntax has been introduced to mod_authz_core.
+# We could just conditionally provide both versions, but unfortunately Apache
+# does not explicitly tell us its version if the module mod_version is not
+# available. In this case, we check for the availability of module
+# mod_authz_core (which should be on 2.4 or higher only) as a best guess.
