+The CMake prepares file AUTHORS for packing.
+It only contains one line, and isn't packed in any upstream-produced packagess.
+I don't find it useful and since upstream doesn't pack it either, stop packing it here.

+
+On the other hand, the README-MySQL isn't prepared for packing by CMake, but contains useful information about the software usage and it is package in upstream-produced packages.
