sftp is an ftp replacement that runs over an ssh tunnel.  Two programs are
included - sftp and sftpserv.  When sftp is run and a host is connected to
(either by running 'sftp remotehost' or 'open remotehost' from the sftp
prompt), an ssh connection is initiated to the remote host, and sftpserv is
run.  So, sftpserv must be in your path on the remote host.  Note that since
sftpserv is run from ssh, no root privileges are necessary.  By default,
sftpserv is expected to be in $PATH on the remote host.  This can be overriden
by passing '--enable-remotepath=<path>' to configure.

The sftp program takes may take several command line options.  Check the
man page for more info.

From within sftp, most of the normal ftp commands are present.  Run 'help' to
get a complete list, or check the man page. 

When building sftp, a link is made to rsftp, which uses rsh instead of ssh.
sftp has been tested with rsh (with and without .rhosts) and ssh1 (with
ssh-agent, password, RSA authentication, and TISAuthentication).  I haven't
tested ssh2, but it should work.  The login process is a bit of a hack, so if
logging in doesn't work, it's a bug and should be fixed.

sftp uses a fairly simple multiplexed protocol over an SSH channel.  The server
is a state machine, and is far more capable than the client.  As an example,
the server theoretically could handle multiple concurrent file transfers, but
the client will only send one.

This was mostly written during the summer of 1998, and resurrected in October,
1999.  Minor updates have been released since then.
