 libssh2 - SSH2 library
 ======================
 
-Version 0.1-dev
----------------
+libssh2 is a library implementing the SSH2 protocol, available under
+the revised BSD license.
 
-  Initial Release:
-    KEX methods: diffie-hellman-group14-sha1, diffie-hellman-group-exchange-sha1, diffie-hellman-group1-sha1
-    Hostkey methods: ssh-rsa, ssh-dss
-    Cipher methods: aes256-cbc, rijndael-cbc@lysator.liu.se, aes192-cbc, aes128-cbc, blowfish-cbc, arcfour, cast128-cbc, 3des-cbc, none*
-    Compression methods: zlib, none
-    MAC methods: hmac-sha1, hmac-sha1-96, hmac-ripemd160, hmac-ripemd160@openssh.com none*
-    *Cipher/MAC "none" is disabled by default for security purposes,
-     Use --enable-crypt-none and/or --enable-mac-none with ./configure to enable
+Generic installation instructions are in INSTALL.  Some ./configure
+options deserve additional comments:
+
+	* --enable-crypt-none
+
+		The SSH2 Transport allows for unencrypted data
+		transmission using the "none" cipher.  Because this is
+		such a huge security hole, it is typically disabled on
+		SSH2 implementations and is disabled in libssh2 by
+		default as well.
+
+		Enabling this option will allow for "none" as a
+		negotiable method, however it still requires that the
+		method be advertized by the remote end and that no
+		more-preferable methods are available.
+
+	* --enable-mac-none
+
+		The SSH2 Transport also allows implementations to
+		forego a message authentication code.  While this is
+		less of a security risk than using a "none" cipher, it
+		is still not recommended as disabling MAC hashes
+		removes a layer of security.
+
+		Enabling this option will allow for "none" as a
+		negotiable method, however it still requires that the
+		method be advertized by the remote end and that no
+		more-preferable methods are available.
+
+	* --disable-gex-new
+
+		The diffie-hellman-group-exchange-sha1 (dh-gex) key
+		exchange method originally defined an exchange
+		negotiation using packet type 30 to request a
+		generation pair based on a single target value.  Later
+		refinement of dh-gex provided for range and target
+		values.  By default libssh2 will use the newer range
+		method.
+
+		If you experience trouble connecting to an old SSH
+		server using dh-gex, try this option to fallback on
+		the older more reliable method.
+
+  	* --with-libgcrypt
+	* --with-libgcrypt-prefix=DIR
+
+		libssh2 can use the Libgcrypt library
+		(http://www.gnupg.org/) for cryptographic operations.
+
+		Configure will attempt to locate Libgcrypt in the
+		default location, but if you have installed it
+		somewhere else, use the --with-libgrypt-prefix=DIR
+		parameter.
+
+	* --with-openssl=[DIR]
+
+		libssh2 can use the OpenSSL library
+		(http://www.openssl.org) for cryptographic operations.
+
+		Configure will attempt to locate OpenSSL in a number
+		of default locations:
+
+			/usr/local/ssl
+			/usr/local
+			/usr
+			/usr/local/openssl
+
+		If your installation of OpenSSL is in another
+		location, specify it here.
+
+	* --with-libz=[DIR]
+
+		If present, libssh2 will attempt to use the zlib (http://www.zlib.org)
+		for payload compression, however zlib is not required.
+
+		Configure will attempt to location a zlib installation
+		in a number of default locations:
+
+			/usr/local
+			/usr
+			/usr/local/libz
+			/usr/libz
+			/usr/local/zlib
+			/usr/zlib
+
+		If your installation of zlib is in another location,
+		you may specify it here.
+
+	* --enable-debug
+
+		Will make the build use more pedantic and strict compiler
+		options as well as enable the libssh2_trace() function (for
+		showing debug traces).

+int
+libssh2_userauth_password(LIBSSH2_SESSION *session, const char *username, const char *password);
+
+.SH DESCRIPTION
+\fIsession\fP - Session instance as returned by 
+.BR libssh2_session_init(3)
+
+\fIusername\fP - Name of user to attempt plain password authentication for.
+
+\fIusername_len\fP - Length of username parameter.
+
+\fIpassword\fP - Password to use for authenticating username.
+
+\fIpassword_len\fP - Length of password parameter.
+
+\fIpasswd_change_cb\fP - If the host accepts authentication but 
+requests that the password be changed, this callback will be issued. 
+If no callback is defined, but server required password change, 
+authentication will fail.
+
+Attempt basic password authentication. Note that many SSH servers 
+which appear to support ordinary password authentication actually have 
+it disabled and use Keyboard Interactive authentication (routed via 
+PAM or another authentication backed) instead.
+
+.SH RETURN VALUE
+Return 0 on success or negative on failure.  It returns
+LIBSSH2_ERROR_EAGAIN when it would otherwise block. While
+LIBSSH2_ERROR_EAGAIN is a negative number, it isn't really a failure per se.
+
+.SH ERRORS
+\fILIBSSH2_ERROR_ALLOC\fP -  An internal memory allocation call failed.
