+        OTP 26 and earlier allows an application to have part of its
+        directories as regular folders and others as archives.
+        This functionality was previously used by reltool but it is
+        no longer the case from OTP 26. Support for archive fallbacks
+        will be removed from the code server in OTP 27.
