+ * Kerberos compatibility functions for AIX's NAS libraries.
+ *
+ * AIX for some reason doesn't provide the krb5_appdefault_* functions, but
+ * does provide the underlying profile library functions (as a separate
+ * libk5profile with a separate k5profile.h header file).
+ *
+ * This file is therefore (apart from the includes, opening and closing
+ * comments, and the spots marked with an rra-c-util comment) a verbatim copy
+ * of src/lib/krb5/krb/appdefault.c from MIT Kerberos 1.4.4.
+ *
+ * The canonical version of this file is maintained in the rra-c-util package,
+ * which can be found at <https://www.eyrie.org/~eagle/software/rra-c-util/>.
+ *
+ * Copyright 1985-2005 by the Massachusetts Institute of Technology.
