Files in a directory with higher priority override files + with the same name in directories of lower priority.

"Drop-in" + files can be overridden in the same way by placing files with the + same name in a directory of higher priority (except that, in case + of "drop-in" files, both the "drop-in" file name and the name of + the containing directory, which corresponds to the name of the + main configuration file, must match).
