External access lists are just char *'s, with the following format:  Begins with a decimal integer in format "%d\n%d\n"
specifying the number of positive entries and negative entries that follow.  This is followed by the list
of entries.  Each entry consists of a
username or groupname followed by a decimal number representing the rights mask for that name.  Each
entry in the list looks as if it had been produced by printf() using a format list of "%s\t%d\n".
