+  * aes.h
+  *
+  * Header file declaring AES functions.
+  *
+  * Copied from the upstream qemu git tree revision
+  *   55616505876d6683130076b810a27c7889321560
+  * but was introduced there by Fabrice Bellard in
+  *   e4d4fe3c34cdd6e26f9b9975efec7d1e81ad00b6
+  *   AES crypto support
+  *   git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@1036 \
+  *     c046a42c-6fe2-441c-8c8c-71466251a162
+  *
+  * Modified by Ian Jackson to change the guard #define from
+  * QEMU_AES_H to AES_H and to add some needed system #include's.
+  *
+  * The header file doesn't appear to have a separate copyright notice
+  * but is clearly a lightly edited (by Bellard) version of code from
+  * Rijmen, Bosselaers and Barreto.
+  *
+  * The original is from rijndael-alg-fst.c, with this copyright
+  * notice:
+  *
+  *   rijndael-alg-fst.c
+  *   
+  *   @version 3.0 (December 2000)
+  *   
+  *   Optimised ANSI C code for the Rijndael cipher (now AES)
