Changes between 0.9.8a and 0.9.9 [xx XXX xxxx]
*) New option -V for 'openssl ciphers'. This prints the ciphersuite code
in addition to the text details.
[Bodo Moeller]
*) Very, very preliminary EXPERIMENTAL support for printing of general
ASN1 structures. This currently produces rather ugly output and doesn't
handle several customised structures at all.
