Version 0.6:
   A *LOT* of minor fixups by  Peter Pentchev ( roam at orbitel dot bg )
   to make it compile cleanly under FreeBSD. Thanks Peter!

Version 0.5: 
   Cleaned up for release. Fixed README, added man pages for aescrypt, 
   aesget. Added 'tobin' program to take a hex string and turn it into
   a binary string, though at the moment I don't know why Randy added
   it (guess he needed it for one of his scripts). 

Version 0.4:
   Changed to use Rijndael instead of Twofish, since it appears that
   Rijndael will be the AES.

Version 0.3:
   Added explicit support for "-" for reading the key off stdin, so that I do
not have to save session keys to disk at any time in order to encrypt or
decrypt streamed session data.

Version 0.2:
   Added GNU Autoconf (Thanks Andy!).
   Changed to using Bruce Schneir's reference TwoFish in order to fix
    BigEndian/LittleEndian problems (maybe!)
