   [readconf.c readconf.h ssh-add.c ssh-keygen.c ssh.c ssh.h sshconnect.c]
   [sshd.c uuencode.c uuencode.h authfile.h]
   - add DSA pubkey auth and other SSH2 fixes.  use ssh-keygen -[xX]
     for trading keys with the real and the original SSH, directly from the
     people who invented the SSH protocol.
   [auth.c auth.h authfile.c sshconnect.c auth1.c auth2.c sshconnect.h]
   [sshconnect1.c sshconnect2.c]
   - split auth/sshconnect in one file per protocol version
   [sshconnect2.c]
   - remove debug
   [uuencode.c]
   - add trailing =
   [version.h]
   - OpenSSH-2.0
   [ssh-keygen.1 ssh-keygen.c]
   - add -R flag: exit code indicates if RSA is alive
   [sshd.c]
   - remove unused
     silent if -Q is specified
   [ssh.h]
   - host key becomes /etc/ssh_host_dsa_key
   [readconf.c servconf.c ]
   - ssh/sshd default to proto 1 and 2
   [uuencode.c]
   - remove debug
   [auth2.c ssh-keygen.c sshconnect2.c sshd.c]
   - xfree DSA blobs
   [auth2.c serverloop.c session.c]
   - cleanup logging for sshd/2, respect PasswordAuth no
   [sshconnect2.c]
   - less debug, respect .ssh/config
