the files and directories immediately inside it.</para>

+ <para>The age of a file system entry is determined from its last
+ modification timestamp (mtime), its last access timestamp (atime),
+ and (except for directories) its last status change timestamp
+ (ctime). Any of these three (or two) values will prevent cleanup
