+.SH DESCRIPTION
+.B ssvncviewer
+is an Xt\-based client application for the VNC (Virtual Network
+Computing) system. It can connect to any VNC\-compatible server such
+as \fBXvnc\fR, WinVNC, or \fBx11vnc\fR, allowing you to control desktop environment
+of a different machine.
+
+ssvncviewer is an enhanced version of the tightvnc unix viewer that can
+take advantage of features in the \fBx11vnc\fR and UltraVNC VNC servers.
+See below for the description of these features.
+
+You can use F8 to display a pop\-up utility menu. Press F8 twice to
+pass single F8 to the remote side.
+.SH OPTIONS
+.TP
+\fB\-help\fR
+Prints a short usage notice to stderr.
+.TP
+\fB\-listen\fR
+Make the viewer listen on port 5500+\fIdisplay\fR for reverse
+connections from a server. WinVNC supports reverse connections using
+the "Add New Client" menu option, or the \-connect command line
+option. \fBXvnc\fR requires the use of the helper program
+\fBvncconnect\fR.
+.TP
+\fB\-via\fR \fIgateway\fR
+Automatically create encrypted TCP tunnel to the \fIgateway\fR machine
+before connection, connect to the \fIhost\fR through that tunnel
+(TightVNC\-specific). By default, this option invokes SSH local port
+forwarding, assuming that SSH client binary can be accessed as
+/usr/bin/ssh. Note that when using the \fB\-via\fR option, the host
+machine name should be specified as known to the gateway machine, e.g. 
+"localhost" denotes the \fIgateway\fR, not the machine where vncviewer
+was launched. See the ENVIRONMENT section below for the information on
+configuring the \fB\-via\fR option.
+.TP
+\fB\-shared\fR
+When connecting, specify that a shared connection is requested. In
+TightVNC, this is the default mode, allowing you to share the desktop
+with other clients already using it.
+.TP
+\fB\-noshared\fR
+When connecting, specify that the session may not be shared. This
+would either disconnect other connected clients or refuse your
+connection, depending on the server configuration.
+.TP
+\fB\-viewonly\fR
+Disable transfer of mouse and keyboard events from the client to the
+server.
+.TP
+\fB\-fullscreen\fR
+Start in full\-screen mode. Please be aware that operating in
+full\-screen mode may confuse X window managers. Typically, such
+conflicts cause incorrect handling of input focus or make the viewer
+window disappear mysteriously. See the grabKeyboard setting in the
+RESOURCES section below for a method to solve input focus problem.
+.TP
+\fB\-noraiseonbeep\fR
+By default, the viewer shows and raises its window on remote beep
+(bell) event. This option disables such behaviour
+(TightVNC\-specific).
+.TP
+\fB\-user\fR \fIusername\fR
+User name for Unix login authentication. Default is to use current
+Unix user name. If this option was given, the viewer will prefer Unix
+login authentication over the standard VNC authentication.
+.TP
+\fB\-passwd\fR \fIpasswd\-file\fR
+File from which to get the password (as generated by the
+\fBvncpasswd\fR(1) program). This option affects only the standard VNC
+authentication.
+.TP
+\fB\-encodings\fR \fIencoding\-list\fR
+TightVNC supports several different compression methods to encode
+screen updates; this option specifies a set of them to use in order of
+preference. Encodings are specified separated with spaces, and must
+thus be enclosed in quotes if more than one is specified.  Commas may be used to avoid spaces.
+Available encodings, in default order for a remote connection, are
+"copyrect tight hextile zlib corre rre raw". For a local connection
+(to the same machine), the default order to try is "raw copyrect tight
+hextile zlib corre rre". Raw encoding is always assumed as a last option
+if no other encoding can be used for some reason. For more information
+on encodings, see the section ENCODINGS below.
+.TP
+\fB\-bgr233\fR
+Always use the BGR233 format to encode pixel data. This reduces
+network traffic, but colors may be represented inaccurately. The
+bgr233 format is an 8\-bit "true color" format, with 2 bits blue, 3
+bits green, and 3 bits red.
+.TP
+\fB\-owncmap\fR
+Try to use a PseudoColor visual and a private colormap. This allows
+the VNC server to control the colormap.
+.TP
+\fB\-truecolour\fR, \fB\-truecolor\fR
+Try to use a TrueColor visual.
+.TP
+\fB\-depth\fR \fIdepth\fR
+On an X server which supports multiple TrueColor visuals of different
+depths, attempt to use the specified one (in bits per pixel); if
+successful, this depth will be requested from the VNC server.
+.TP
+\fB\-compresslevel \fIlevel\fR
+Use specified compression \fIlevel\fR (0..9) for "tight" and "zlib"
+encodings (TightVNC\-specific). Level 1 uses minimum of CPU time and
+achieves weak compression ratios, while level 9 offers best
+compression but is slow in terms of CPU time consumption on the server
+side. Use high levels with very slow network connections, and low
+levels when working over high\-speed LANs. It's not recommended to use
+compression level 0, reasonable choices start from the level 1.
+.TP
+\fB\-quality \fIlevel\fR
+Use the specified JPEG quality \fIlevel\fR (0..9) for the "tight"
+encoding (TightVNC\-specific). Quality level 0 denotes bad image
+quality but very impressive compression ratios, while level 9 offers
+very good image quality at lower compression ratios. Note that the
+"tight" encoder uses JPEG to encode only those screen areas that look
+suitable for lossy compression, so quality level 0 does not always
+mean unacceptable image quality.
+.TP
+\fB\-nojpeg\fR
+Disable lossy JPEG compression in Tight encoding (TightVNC\-specific). 
+Disabling JPEG compression is not a good idea in typical cases, as
+that makes the Tight encoder less efficient. You might want to use
+this option if it's absolutely necessary to achieve perfect image
+quality (see also the \fB\-quality\fR option).
+.TP
+\fB\-nocursorshape\fR
+Disable cursor shape updates, protocol extensions used to handle
+remote cursor movements locally on the client side
+(TightVNC\-specific). Using cursor shape updates decreases delays with
+remote cursor movements, and can improve bandwidth usage dramatically. 
+.TP
+\fB\-x11cursor\fR
+Use a real X11 cursor with X-style cursor shape updates, instead of
+drawing the remote cursor on the framebuffer. This option also
+disables the dot cursor, and disables cursor position updates in
+non-fullscreen mode.
+.TP
+\fB\-autopass\fR
+Read a plain-text password from stdin. This option affects only the
+standard VNC authentication.
+
+.SH Enhanced TightVNC Viewer (SSVNC) OPTIONS
+.TP
+Enhanced TightVNC Viewer (SSVNC) web page is located at:
+.TP
+http://www.karlrunge.com/x11vnc/ssvnc.html
+.TP
+Note: ZRLE and ZYWRLE encodings are now supported.
+.TP
+Note: F9 is shortcut to Toggle FullScreen mode.
+.TP
+Note: In -listen mode set the env var. SSVNC_MULTIPLE_LISTEN=1
+to allow more than one incoming VNC server at a time.
+This is the same as -multilisten described below.  Set
+SSVNC_MULTIPLE_LISTEN=MAX:n to allow no more than "n"
+simultaneous reverse connections.
+
+If the host:port is specified as "exec=command args..."
+then instead of making a TCP/IP socket connection to the
+remote VNC server, "command args..." is executed and the
+viewer is attached to its stdio.  This enables tunnelling
+established via an external command, e.g. an stunnel(8)
+that does not involve a listening socket.
+This mode does not work for -listen reverse connections.
+
+If the host:port is specified as "fd=n" then it is assumed
+n is an already opened file descriptor to the socket. (i.e
+the parent did fork+exec)
+
+If the host:port contains a '/' it is interpreted as a
+unix-domain socket (AF_LOCAL insead of AF_INET)
+.TP
+\fB\-multilisten\fR
+As in -listen (reverse connection listening) except
+allow more than one incoming VNC server to be connected
+at a time.  The default for -listen of only one at a
+time tries to play it safe by not allowing anyone on
+the network to put (many) desktops on your screen over
+a long window of time. Use -multilisten for no limit.
+.TP
+\fB\-acceptpopup\fR
+In \fB\-listen\fR (reverse connection listening) mode when
+a reverse VNC connection comes in show a popup asking
+whether to Accept or Reject the connection.  The IP
+address of the connecting host is shown.  Same as
+setting the env. var. SSVNC_ACCEPT_POPUP=1.
+.TP
+\fB\-acceptpopupsc\fR
+As in \fB\-acceptpopup\fR except assume UltraVNC Single
+Click (SC) server.  Retrieve User and ComputerName
+info from UltraVNC Server and display in the Popup.
+.TP
+\fB\-use64\fR
+In \fB\-bgr233\fR mode, use 64 colors instead of 256.
+.TP
+\fB\-bgr222\fR
+Same as \fB\-use64\fR.
+.TP
+\fB\-use8\fR
+In \fB\-bgr233\fR mode, use 8 colors instead of 256.
+.TP
+\fB\-bgr111\fR
+Same as \fB\-use8\fR.
+.TP
+\fB\-16bpp\fR
+If the vnc viewer X display is depth 24 at 32bpp
+request a 16bpp format from the VNC server to cut
+network traffic by up to 2X, then tranlate the
+pixels to 32bpp locally.
+.TP
+\fB\-bgr565\fR
+Same as \fB\-16bpp\fR.
+.TP
+\fB\-grey\fR
+Use a grey scale for the 16- and 8\fB\-bpp\fR modes.
+.TP
+\fB\-alpha\fR
+Use alphablending transparency for local cursors
+requires: x11vnc server, both client and server
+must be 32bpp and same endianness.
+.TP
+\fB\-scale\fR \fIstr\fR
+Scale the desktop locally.  The string "str" can
+a floating point ratio, e.g. "0.9", or a fraction,
+e.g. "3/4", or WxH, e.g. 1280x1024.  Use "fit"
+to fit in the current screen size.  Use "auto" to
+fit in the window size.  "str" can also be set by
+the env. var. SSVNC_SCALE.
+
+If you observe mouse trail painting errors, enable
+X11 Cursor mode (either via Popup or \fB\-x11cursor\fR.)
+
+Note that scaling is done in software and so can be
+slow and requires more memory.  Some speedup Tips:
+
+ZRLE is faster than Tight in this mode.  When
+scaling is first detected, the encoding will
+be automatically switched to ZRLE.  Use the
+Popup menu if you want to go back to Tight.
+Set SSVNC_PRESERVE_ENCODING=1 to disable this.
+
+Use a solid background on the remote side.
+(e.g. manually or via x11vnc \fB\-solid\fR ...)
+
+If the remote server is x11vnc, try client
+side caching: x11vnc \fB\-ncache\fR 10 ...
+.TP
+\fB\-ycrop\fR n
+Only show the top n rows of the framebuffer.  For
+use with x11vnc \fB\-ncache\fR client caching option
+to help "hide" the pixel cache region.
+Use a negative value (e.g. \fB\-1\fR) for autodetection.
+Autodetection will always take place if the remote
+fb height is more than 2 times the width.
+.TP
+\fB\-sbwidth\fR n
+Scrollbar width for x11vnc \fB\-ncache\fR mode (\fB\-ycrop\fR),
+default is very narrow: 2 pixels, it is narrow to
+avoid distraction in \fB\-ycrop\fR mode.
+.TP
+\fB\-nobell\fR
+Disable bell.
+.TP
+\fB\-rawlocal\fR
+Prefer raw encoding for localhost, default is
+no, i.e. assumes you have a SSH tunnel instead.
+.TP
+\fB\-notty\fR
+Try to avoid using the terminal for interactive
+responses: use windows for messages and prompting
+instead.  Messages will also be printed to terminal.
+.TP
+\fB\-sendclipboard\fR
+Send the X CLIPBOARD selection (i.e. Ctrl+C,
+Ctrl+V) instead of the X PRIMARY selection (mouse
+select and middle button paste.)
+.TP
+\fB\-sendalways\fR
+Whenever the mouse enters the VNC viewer main
+window, send the selection to the VNC server even if
+it has not changed.  This is like the Xt resource
+translation SelectionToVNC(always)
+.TP
+\fB\-recvtext\fR
+str   When cut text is received from the VNC server,
+ssvncviewer will set both the X PRIMARY and the
+X CLIPBOARD local selections.  To control which
+is set, specify 'str' as 'primary', 'clipboard',
+or 'both' (the default.)
+.TP
+\fB\-graball\fR
+Grab the entire X server when in fullscreen mode,
+needed by some old window managers like fvwm2.
+.TP
+\fB\-popupfix\fR
+Warp the popup back to the pointer position,
+needed by some old window managers like fvwm2.
+.TP
+\fB\-grabkbd\fR
+Grab the X keyboard when in fullscreen mode,
+needed by some window managers. Same as \fB\-grabkeyboard\fR.
+\fB\-grabkbd\fR is the default, use \fB\-nograbkbd\fR to disable.
+.TP
+\fB\-bs\fR, \fB\-nobs\fR
+Whether or not to use X server Backingstore for the
+main viewer window.  The default is to not, mainly
+because most Linux, etc, systems X servers disable
+*all* Backingstore by default.  To re\fB\-enable\fR it put
+
+Option "Backingstore"
+
+in the Device section of /etc/X11/xorg.conf.
+In \fB\-bs\fR mode with no X server backingstore, whenever an
+area of the screen is re\fB\-exposed\fR it must go out to the
+VNC server to retrieve the pixels. This is too slow.
+
+In \fB\-nobs\fR mode, memory is allocated by the viewer to
+provide its own backing of the main viewer window. This
+actually makes some activities faster (changes in large
+regions) but can appear to "flash" too much.
+.TP
+\fB\-noshm\fR
+Disable use of MIT shared memory extension (not recommended)
+.TP
+\fB\-termchat\fR
+Do the UltraVNC chat in the terminal vncviewer is in
+instead of in an independent window.
+.TP
+\fB\-unixpw\fR \fIstr\fR
+Useful for logging into x11vnc in \fB\-unixpw\fR mode. "str" is a
+string that allows many ways to enter the Unix Username
+and Unix Password.  These characters: username, newline,
+password, newline are sent to the VNC server after any VNC
+authentication has taken place.  Under x11vnc they are
+used for the \fB\-unixpw\fR login.  Other VNC servers could do
+something similar.
+
+You can also indicate "str" via the environment
+variable SSVNC_UNIXPW.
+
+Note that the Escape key is actually sent first to tell
+x11vnc to not echo the Unix Username back to the VNC
+viewer. Set SSVNC_UNIXPW_NOESC=1 to override this.
+
+If str is ".", then you are prompted at the command line
+for the username and password in the normal way.  If str is
+"-" the stdin is read via getpass(3) for username@password.
+Otherwise if str is a file, it is opened and the first line
+read is taken as the Unix username and the 2nd as the
+password. If str prefixed by "rm:" the file is removed
+after reading. Otherwise, if str has a "@" character,
+it is taken as username@password. Otherwise, the program
+exits with an error. Got all that?
+.TP
+\fB-repeater\fR \fIstr\fR
+This is for use with UltraVNC repeater proxy described
+here: http://www.uvnc.com/addons/repeater.html.  The "str"
+is the ID string to be sent to the repeater.  E.g. ID:1234
+It can also be the hostname and port or display of the VNC
+server, e.g. 12.34.56.78:0 or snoopy.com:1.  Note that when
+using -repeater, the host:dpy on the cmdline is the repeater
+server, NOT the VNC server.  The repeater will connect you.
+
+Example: vncviewer ... -repeater ID:3333 repeat.host:5900
+
+Example: vncviewer ... -repeater vhost:0 repeat.host:5900
+
+Use, e.g., '-repeater SCIII=ID:3210' if the repeater is a
+Single Click III (SSL) repeater (repeater_SSL.exe) and you
+are passing the SSL part of the connection through stunnel, socat, etc.
+This way the magic UltraVNC string 'testB' needed to work with the
+repeater is sent to it.
+.TP
+\fB-rfbversion\fR \fIstr\fR
+Set the advertised RFB version.  E.g.: -rfbversion 3.6  For some
+servers, e.g. UltraVNC this needs to be done.
+.TP
+\fB-ultradsm\fR
+UltraVNC has symmetric private encryption DSM plugins.  See
+http://www.uvnc.com/features/encryption.html.  It is assumed
+you are using a unix program (e.g. our ultravnc_dsm_helper) to
+encrypt and decrypt the UltraVNC DSM stream. IN ADDITION TO
+THAT supply -ultradsm to tell THIS viewer to modify the RFB
+data sent so as to work with the UltraVNC Server.  For some
+reason, each RFB msg type must be sent twice under DSM.
+.TP
+\fB\-mslogon\fR \fIuser\fR
+Use Windows MS Logon to an UltraVNC server.  Supply the
+username or "1" to be prompted.  The default is to
+autodetect the UltraVNC MS Logon server and prompt for
+the username and password.
+
+IMPORTANT NOTE: The UltraVNC MS-Logon Diffie-Hellman
+exchange is very weak and can be brute forced to recover
+your username and password in a few seconds of CPU
+time.  To be safe, be sure to use an additional encrypted
+tunnel (e.g. SSL or SSH) for the entire VNC session.
+.TP
+\fB\-chatonly\fR
+Try to be a client that only does UltraVNC text chat. This
+mode is used by x11vnc to present a chat window on the physical
+X11 console (i.e. to chat with the person at the display).
+.TP
+\fB-env\fR \fIVAR=VALUE\fR
+To save writing a shell script to set environment
+variables, specify as many as you need on the command line.  For example,
+-env SSVNC_MULTIPLE_LISTEN=MAX:5 -env EDITOR=vi
+.TP
+\fB\-noipv6\fR
+Disable all IPv6 sockets.  Same as VNCVIEWER_NO_IPV6=1.
+.TP
+\fB\-noipv4\fR
+Disable all IPv4 sockets.  Same as VNCVIEWER_NO_IPV4=1.
+.TP
+\fB\-printres\fR
+Print out the Ssvnc X resources (appdefaults) and
+then exit. You can save them to a file and customize them (e.g. the
+keybindings and Popup menu)  Then point to the file via
+XENVIRONMENT or XAPPLRESDIR.
+.TP
+\fB\-pipeline\fR
+Like TurboVNC, request the next framebuffer update as soon
+as possible instead of waiting until the end of the current
+framebuffer update coming in.  Helps 'pipeline' the updates.
+This is currently the default, use \fB-nopipeline\fR to disable.
+.TP
+\fB\-appshare\fR
+Enable features for use with x11vnc's \fB\-appshare\fR mode where
+instead of sharing the full desktop only the application's
+windows are shared.  Viewer multilisten mode is used to
+create the multiple windows: \fB\-multilisten\fR is implied.
+See 'x11vnc \fB\-appshare\fR \fB\-help\fR' more information on the mode.
+Features enabled in the viewer under \fB\-appshare\fR are:
+Minimum extra text in the title, auto \fB\-ycrop\fR is disabled,
+x11vnc \fB\-remote_prefix\fR X11VNC_APPSHARE_CMD: message channel,
+x11vnc initial window position hints.  See also Escape Keys
+below for additional key and mouse bindings.
+.TP
+\fB\-escape \fR\fIstr\fR
+This sets the 'Escape Keys' modifier sequence and enables
+escape keys mode.  When the modifier keys escape sequence
+is held down, the next keystroke is interpreted locally
+to perform a special action instead of being sent to the
+remote VNC server.
+
+Use '\fB\-escape\fR default' for the default modifier sequence.
+(Unix: Alt_L,Super_L and MacOSX: Control_L,Meta_L)
+
+Here are the 'Escape Keys: Help+Set' instructions from the Popup:
+
+Escape Keys:  Enter a comma separated list of modifier keys to be the 'escape
+sequence'.  When these keys are held down, the next keystroke is
+interpreted locally to invoke a special action instead of being sent to
+the remote VNC server.  In other words, a set of 'Hot Keys'.
+
+Here is the list of local key mappings to special actions:
+
+r: refresh desktop  b: toggle bell  c: toggle full-color
+
+f: file transfer    x: x11cursor    z: toggle Tight/ZRLE
+
+l: full screen      g: graball      e: escape keys dialog
+
+s: scale dialog     +: scale up (=) -: scale down (_)
+
+t: text chat                        a: alphablend cursor
+
+V: toggle viewonly  Q: quit viewer  123456: UltraVNC scale 1/n
+
+Arrow keys: pan the viewport about 10% for each keypress.
+
+PageUp/PageDown: pan the viewport by a screenful vertically.
+
+Home/End: pan the viewport by a screenful horizontally.
+
+KeyPad Arrows: pan the viewport by 1 pixel for each keypress.
+
+Dragging the Mouse with Button1 pressed also pans the viewport.
+
+Clicking Mouse Button3 brings up the Popup Menu.
+
+The above mappings are \fBalways\fR active in ViewOnly mode, unless you set
+the Escape Keys value to 'never'.
+
+x11vnc -appshare hot-keys:  x11vnc has a simple application sharing mode
+that enables the viewer-side to move, resize, or raise the remote toplevel
+windows.  To enable it, hold down Shift + the Escape Keys and press these:
+
+Arrow keys: move the remote window around in its desktop.
+
+PageUp/PageDn/Home/End:  resize the remote window.
+
++/-: raise or lower the remote window.
+
+M or Button1 move win to local position;  D or Button3: delete remote win.
+
+If the Escape Keys value below is set to 'default' then a default list of
+of modifier keys is used.  For Unix it is: Alt_L,Super_L and for MacOSX it
+is Control_L,Meta_L.  Note: the Super_L key usually has a Windows(TM) Flag
+on it.  Also note the _L and _R mean the key is on the LEFT or RIGHT side
+of the keyboard.
+
+On Unix   the default is Alt and Windows keys on Left side of keyboard.
+On MacOSX the default is Control and Command keys on Left side of keyboard.
+
+Example: Press and hold the Alt and Windows keys on the LEFT side of the
+keyboard and then press 'c' to toggle the full-color state.  Or press 't'
+to toggle the ultravnc Text Chat window, etc.
+
+To use something besides the default, supply a comma separated list (or a
+single one) from: Shift_L Shift_R Control_L Control_R Alt_L Alt_R Meta_L
+Meta_R Super_L Super_R Hyper_L Hyper_R or Mode_switch.

+
+.SH ENCODINGS
+The server supplies information in whatever format is desired by the
+client, in order to make the client as easy as possible to implement. 
+If the client represents itself as able to use multiple formats, the
+server will choose one.
+
+.I Pixel format
+refers to the representation of an individual pixel. The most common
+formats are 24 and 16 bit "true\-color" values, and 8\-bit "color map"
+representations, where an arbitrary map converts the color number to
+RGB values.
+
+.I Encoding
+refers to how a rectangle of pixels are sent (all pixel information in
+VNC is sent as rectangles). All rectangles come with a header giving
+the location and size of the rectangle and an encoding type used by
+the data which follows. These types are listed below.
+.TP
+.B Raw
+The raw encoding simply sends width*height pixel values. All clients
+are required to support this encoding type. Raw is also the fastest
+when the server and viewer are on the same machine, as the connection
+speed is essentially infinite and raw encoding minimizes processing
+time.
+.TP
+.B CopyRect
+The Copy Rectangle encoding is efficient when something is being
+moved; the only data sent is the location of a rectangle from which
+data should be copied to the current location. Copyrect could also be
+used to efficiently transmit a repeated pattern.
+.TP
+.B RRE
+The Rise\-and\-Run\-length\-Encoding is basically a 2D version of
+run\-length encoding (RLE). In this encoding, a sequence of identical
+pixels are compressed to a single value and repeat count. In VNC, this
+is implemented with a background color, and then specifications of an
+arbitrary number of subrectangles and color for each. This is an
+efficient encoding for large blocks of constant color.
+.TP
+.B CoRRE
+This is a minor variation on RRE, using a maximum of 255x255 pixel
+rectangles. This allows for single\-byte values to be used, reducing
+packet size. This is in general more efficient, because the savings
+from sending 1\-byte values generally outweighs the losses from the
+(relatively rare) cases where very large regions are painted the same
+color.
+.TP
+.B Hextile
+Here, rectangles are split up in to 16x16 tiles, which are sent in a
+predetermined order. The data within the tiles is sent either raw or
+as a variant on RRE. Hextile encoding is usually the best choice for
+using in high\-speed network environments (e.g. Ethernet local\-area
+networks).
+.TP
+.B Zlib
+Zlib is a very simple encoding that uses zlib library to compress raw
+pixel data. This encoding achieves good compression, but consumes a
+lot of CPU time. Support for this encoding is provided for
+compatibility with VNC servers that might not understand Tight
+encoding which is more efficient than Zlib in nearly all real\-life
+situations.
+.TP
+.B Tight
+Like Zlib encoding, Tight encoding uses zlib library to compress the
+pixel data, but it pre\-processes data to maximize compression ratios,
+and to minimize CPU usage on compression. Also, JPEG compression may
+be used to encode color\-rich screen areas (see the description of
+\-quality and \-nojpeg options above). Tight encoding is usually the
+best choice for low\-bandwidth network environments (e.g. slow modem
+connections).
+.TP
+.B ZRLE
+The SSVNC viewer has ported the RealVNC (www.realvnc.com) ZRLE encoding
+to the unix tightvnc viewer.
+.TP
+.B ZYWRLE
+The SSVNC viewer has ported the Hitachi lossy wavelet based ZRLE
+encoding from http://mobile.hitachi-system.co.jp/publications/ZYWRLE/ 
+to the unix tightvnc viewer.

+.TP
+.B useRemoteCursor
+Equivalent of \fB\-nocursorshape\fR option, when set to false
+(TightVNC\-specific). Default true.
+.TP
+.B useBGR233
+Equivalent of \fB\-bgr233\fR option. Default false.
+.TP
+.B nColours
+When using BGR233, try to allocate this many "exact" colors from the
+BGR233 color cube. When using a shared colormap, setting this resource
+lower leaves more colors for other X clients. Irrelevant when using
+truecolor. Default is 256 (i.e. all of them).
+.TP
+.B useSharedColours
+If the number of "exact" BGR233 colors successfully allocated is less
+than 256 then the rest are filled in using the "nearest" colors
+available. This resource says whether to only use the "exact" BGR233
+colors for this purpose, or whether to use other clients' "shared"
+colors as well. Default true (i.e. use other clients' colors).
+.TP
+.B forceOwnCmap
+Equivalent of \fB\-owncmap\fR option. Default false.
+.TP
+.B forceTrueColour
+Equivalent of \fB\-truecolour\fR option. Default false.
+.TP
+.B requestedDepth
+Equivalent of \fB\-depth\fR option.
+.TP
+.B useSharedMemory
+Use MIT shared memory extension if on the same machine as the X
+server. Default true.
+.TP
+.B wmDecorationWidth, wmDecorationHeight
+The total width and height taken up by window manager decorations.
+This is used to calculate the maximum size of the VNC viewer window. 
+Default is width 4, height 24.
+.TP
+.B bumpScrollTime, bumpScrollPixels
+When in full screen mode and the VNC desktop is bigger than the X
+display, scrolling happens whenever the mouse hits the edge of the
+screen. The maximum speed of scrolling is bumpScrollPixels pixels
+every bumpScrollTime milliseconds. The actual speed of scrolling will
+be slower than this, of course, depending on how fast your machine is. 
+Default 20 pixels every 25 milliseconds.
+.TP
+.B popupButtonCount
+The number of buttons in the popup window. See the README file for
+more information on how to customize the buttons.
+.TP
+.B debug
+For debugging. Default false.
+.TP
+.B rawDelay, copyRectDelay
+For debugging, see the README file for details. Default 0 (off).
+.SH ENVIRONMENT
+When started with the \fB\-via\fR option, vncviewer reads the
+\fBVNC_VIA_CMD\fR environment variable, expands patterns beginning
+with the "%" character, and executes result as a command assuming that
+it would create TCP tunnel that should be used for VNC connection. If
+not set, this environment variable defaults to "/usr/bin/ssh -f -L
+%L:%H:%R %G sleep 20".
+
+The following patterns are recognized in the \fBVNC_VIA_CMD\fR (note
+that all the patterns %G, %H, %L and %R must be present in the command
+template):
+.TP
+.B %%
+A literal "%";
+.TP
+.B %G
+gateway host name;
+.TP
+.B %H
+remote VNC host name, as known to the gateway;
+.TP
+.B %L
+local TCP port number;
+.TP
+.B %R
+remote TCP port number.

 .SH DESCRIPTION
-.B vncviewer
+.B ssvncviewer
 is an Xt\-based client application for the VNC (Virtual Network
 Computing) system. It can connect to any VNC\-compatible server such
-as \fBXvnc\fR or WinVNC, allowing you to control desktop environment
+as \fBXvnc\fR, WinVNC, or \fBx11vnc\fR, allowing you to control desktop environment
 of a different machine.
 
+ssvncviewer is an enhanced version of the tightvnc unix viewer that can
+take advantage of features in the \fBx11vnc\fR and UltraVNC VNC servers.
+See below for the description of these features.
+
 You can use F8 to display a pop\-up utility menu. Press F8 twice to
 pass single F8 to the remote side.

+Note: ZRLE and ZYWRLE encodings are now supported.

+Note: F9 is shortcut to Toggle FullScreen mode.
+.TP
+Note: In -listen mode set the env var. SSVNC_MULTIPLE_LISTEN=1
+to allow more than one incoming VNC server at a time.
+This is the same as -multilisten described below.  Set
+SSVNC_MULTIPLE_LISTEN=MAX:n to allow no more than "n"
+simultaneous reverse connections.
+
+If the host:port is specified as "exec=command args..."
+then instead of making a TCP/IP socket connection to the
+remote VNC server, "command args..." is executed and the
+viewer is attached to its stdio.  This enables tunnelling
+established via an external command, e.g. an stunnel(8)
+that does not involve a listening socket.
+This mode does not work for -listen reverse connections.
+
+If the host:port is specified as "fd=n" then it is assumed
+n is an already opened file descriptor to the socket. (i.e
+the parent did fork+exec)
+
+If the host:port contains a '/' it is interpreted as a
+unix-domain socket (AF_LOCAL insead of AF_INET)

+\fB\-acceptpopup\fR
+In \fB\-listen\fR (reverse connection listening) mode when
+a reverse VNC connection comes in show a popup asking
+whether to Accept or Reject the connection.  The IP
+address of the connecting host is shown.  Same as
+setting the env. var. SSVNC_ACCEPT_POPUP=1.
+.TP
+\fB\-acceptpopupsc\fR
+As in \fB\-acceptpopup\fR except assume UltraVNC Single
+Click (SC) server.  Retrieve User and ComputerName
+info from UltraVNC Server and display in the Popup.
+.TP
+\fB\-use64\fR
+In \fB\-bgr233\fR mode, use 64 colors instead of 256.
+.TP
+\fB\-bgr222\fR
+Same as \fB\-use64\fR.
+.TP
+\fB\-use8\fR
+In \fB\-bgr233\fR mode, use 8 colors instead of 256.
+.TP
+\fB\-bgr111\fR
+Same as \fB\-use8\fR.
+.TP
+\fB\-16bpp\fR
+If the vnc viewer X display is depth 24 at 32bpp
+request a 16bpp format from the VNC server to cut
+network traffic by up to 2X, then tranlate the
+pixels to 32bpp locally.
+.TP
+\fB\-bgr565\fR
+Same as \fB\-16bpp\fR.
+.TP
+\fB\-grey\fR
+Use a grey scale for the 16- and 8\fB\-bpp\fR modes.
+.TP
+\fB\-alpha\fR
+Use alphablending transparency for local cursors
+requires: x11vnc server, both client and server
+must be 32bpp and same endianness.
+.TP
+\fB\-scale\fR \fIstr\fR
+Scale the desktop locally.  The string "str" can
+a floating point ratio, e.g. "0.9", or a fraction,
+e.g. "3/4", or WxH, e.g. 1280x1024.  Use "fit"
+to fit in the current screen size.  Use "auto" to
+fit in the window size.  "str" can also be set by
+the env. var. SSVNC_SCALE.
+
+If you observe mouse trail painting errors, enable
+X11 Cursor mode (either via Popup or \fB\-x11cursor\fR.)
+
+Note that scaling is done in software and so can be
+slow and requires more memory.  Some speedup Tips:
+
+ZRLE is faster than Tight in this mode.  When
+scaling is first detected, the encoding will
+be automatically switched to ZRLE.  Use the
+Popup menu if you want to go back to Tight.
+Set SSVNC_PRESERVE_ENCODING=1 to disable this.
+
+Use a solid background on the remote side.
+(e.g. manually or via x11vnc \fB\-solid\fR ...)
+
+If the remote server is x11vnc, try client
+side caching: x11vnc \fB\-ncache\fR 10 ...
+.TP
+\fB\-ycrop\fR n
+Only show the top n rows of the framebuffer.  For
+use with x11vnc \fB\-ncache\fR client caching option
+to help "hide" the pixel cache region.
+Use a negative value (e.g. \fB\-1\fR) for autodetection.
+Autodetection will always take place if the remote
+fb height is more than 2 times the width.
+.TP
+\fB\-sbwidth\fR n
+Scrollbar width for x11vnc \fB\-ncache\fR mode (\fB\-ycrop\fR),
+default is very narrow: 2 pixels, it is narrow to
+avoid distraction in \fB\-ycrop\fR mode.
+.TP
+\fB\-nobell\fR
+Disable bell.
+.TP
+\fB\-rawlocal\fR
+Prefer raw encoding for localhost, default is
+no, i.e. assumes you have a SSH tunnel instead.
+.TP
+\fB\-notty\fR
+Try to avoid using the terminal for interactive
+responses: use windows for messages and prompting
+instead.  Messages will also be printed to terminal.
+.TP
+\fB\-sendclipboard\fR
+Send the X CLIPBOARD selection (i.e. Ctrl+C,
+Ctrl+V) instead of the X PRIMARY selection (mouse
+select and middle button paste.)
+.TP
+\fB\-sendalways\fR
+Whenever the mouse enters the VNC viewer main
+window, send the selection to the VNC server even if
+it has not changed.  This is like the Xt resource
+translation SelectionToVNC(always)
+.TP
+\fB\-recvtext\fR
+str   When cut text is received from the VNC server,
+ssvncviewer will set both the X PRIMARY and the
+X CLIPBOARD local selections.  To control which
+is set, specify 'str' as 'primary', 'clipboard',
+or 'both' (the default.)
+.TP
+\fB\-graball\fR
+Grab the entire X server when in fullscreen mode,
+needed by some old window managers like fvwm2.
+.TP
+\fB\-popupfix\fR
+Warp the popup back to the pointer position,
+needed by some old window managers like fvwm2.
+.TP
+\fB\-grabkbd\fR
+Grab the X keyboard when in fullscreen mode,
+needed by some window managers. Same as \fB\-grabkeyboard\fR.
+\fB\-grabkbd\fR is the default, use \fB\-nograbkbd\fR to disable.
+.TP
+\fB\-bs\fR, \fB\-nobs\fR
+Whether or not to use X server Backingstore for the
+main viewer window.  The default is to not, mainly
+because most Linux, etc, systems X servers disable
+*all* Backingstore by default.  To re\fB\-enable\fR it put
+
+Option "Backingstore"
+
+in the Device section of /etc/X11/xorg.conf.
+In \fB\-bs\fR mode with no X server backingstore, whenever an
+area of the screen is re\fB\-exposed\fR it must go out to the
+VNC server to retrieve the pixels. This is too slow.
+
+In \fB\-nobs\fR mode, memory is allocated by the viewer to
+provide its own backing of the main viewer window. This
+actually makes some activities faster (changes in large
+regions) but can appear to "flash" too much.
+.TP
+\fB\-noshm\fR
+Disable use of MIT shared memory extension (not recommended)
+.TP
+\fB\-termchat\fR
+Do the UltraVNC chat in the terminal vncviewer is in
+instead of in an independent window.
+.TP
+\fB\-unixpw\fR \fIstr\fR
+Useful for logging into x11vnc in \fB\-unixpw\fR mode. "str" is a
+string that allows many ways to enter the Unix Username
+and Unix Password.  These characters: username, newline,
+password, newline are sent to the VNC server after any VNC
+authentication has taken place.  Under x11vnc they are
+used for the \fB\-unixpw\fR login.  Other VNC servers could do
+something similar.
+
+You can also indicate "str" via the environment
+variable SSVNC_UNIXPW.
+
+Note that the Escape key is actually sent first to tell
+x11vnc to not echo the Unix Username back to the VNC
+viewer. Set SSVNC_UNIXPW_NOESC=1 to override this.
+
+If str is ".", then you are prompted at the command line
+for the username and password in the normal way.  If str is
+"-" the stdin is read via getpass(3) for username@password.
+Otherwise if str is a file, it is opened and the first line
+read is taken as the Unix username and the 2nd as the
+password. If str prefixed by "rm:" the file is removed
+after reading. Otherwise, if str has a "@" character,
+it is taken as username@password. Otherwise, the program
+exits with an error. Got all that?
+.TP
+\fB-repeater\fR \fIstr\fR
+This is for use with UltraVNC repeater proxy described
+here: http://www.uvnc.com/addons/repeater.html.  The "str"
+is the ID string to be sent to the repeater.  E.g. ID:1234
+It can also be the hostname and port or display of the VNC
+server, e.g. 12.34.56.78:0 or snoopy.com:1.  Note that when
+using -repeater, the host:dpy on the cmdline is the repeater
+server, NOT the VNC server.  The repeater will connect you.
+
+Example: vncviewer ... -repeater ID:3333 repeat.host:5900
+
+Example: vncviewer ... -repeater vhost:0 repeat.host:5900
+
+Use, e.g., '-repeater SCIII=ID:3210' if the repeater is a
+Single Click III (SSL) repeater (repeater_SSL.exe) and you
+are passing the SSL part of the connection through stunnel, socat, etc.
+This way the magic UltraVNC string 'testB' needed to work with the
+repeater is sent to it.
+.TP
+\fB-rfbversion\fR \fIstr\fR
+Set the advertised RFB version.  E.g.: -rfbversion 3.6  For some
+servers, e.g. UltraVNC this needs to be done.
+.TP
+\fB-ultradsm\fR
+UltraVNC has symmetric private encryption DSM plugins.  See
+http://www.uvnc.com/features/encryption.html.  It is assumed
+you are using a unix program (e.g. our ultravnc_dsm_helper) to
+encrypt and decrypt the UltraVNC DSM stream. IN ADDITION TO
+THAT supply -ultradsm to tell THIS viewer to modify the RFB
+data sent so as to work with the UltraVNC Server.  For some
+reason, each RFB msg type must be sent twice under DSM.
+.TP
+\fB\-mslogon\fR \fIuser\fR
+Use Windows MS Logon to an UltraVNC server.  Supply the
+username or "1" to be prompted.  The default is to
+autodetect the UltraVNC MS Logon server and prompt for
+the username and password.
+
+IMPORTANT NOTE: The UltraVNC MS-Logon Diffie-Hellman
+exchange is very weak and can be brute forced to recover
+your username and password in a few seconds of CPU
+time.  To be safe, be sure to use an additional encrypted
+tunnel (e.g. SSL or SSH) for the entire VNC session.
+.TP
+\fB\-chatonly\fR
+Try to be a client that only does UltraVNC text chat. This
+mode is used by x11vnc to present a chat window on the physical
+X11 console (i.e. to chat with the person at the display).
+.TP
+\fB-env\fR \fIVAR=VALUE\fR
+To save writing a shell script to set environment
+variables, specify as many as you need on the command line.  For example,
+-env SSVNC_MULTIPLE_LISTEN=MAX:5 -env EDITOR=vi
+.TP
+\fB\-noipv6\fR
+Disable all IPv6 sockets.  Same as VNCVIEWER_NO_IPV6=1.
+.TP
+\fB\-noipv4\fR
+Disable all IPv4 sockets.  Same as VNCVIEWER_NO_IPV4=1.
+.TP
+\fB\-printres\fR
+Print out the Ssvnc X resources (appdefaults) and
+then exit. You can save them to a file and customize them (e.g. the
+keybindings and Popup menu)  Then point to the file via
+XENVIRONMENT or XAPPLRESDIR.
+.TP
+\fB\-pipeline\fR
+Like TurboVNC, request the next framebuffer update as soon
+as possible instead of waiting until the end of the current
+framebuffer update coming in.  Helps 'pipeline' the updates.
+This is currently the default, use \fB-nopipeline\fR to disable.
+.TP
+\fB\-appshare\fR
+Enable features for use with x11vnc's \fB\-appshare\fR mode where
+instead of sharing the full desktop only the application's
+windows are shared.  Viewer multilisten mode is used to
+create the multiple windows: \fB\-multilisten\fR is implied.
+See 'x11vnc \fB\-appshare\fR \fB\-help\fR' more information on the mode.
+Features enabled in the viewer under \fB\-appshare\fR are:
+Minimum extra text in the title, auto \fB\-ycrop\fR is disabled,
+x11vnc \fB\-remote_prefix\fR X11VNC_APPSHARE_CMD: message channel,
+x11vnc initial window position hints.  See also Escape Keys
+below for additional key and mouse bindings.
+.TP
+\fB\-escape \fR\fIstr\fR
+This sets the 'Escape Keys' modifier sequence and enables
+escape keys mode.  When the modifier keys escape sequence
+is held down, the next keystroke is interpreted locally
+to perform a special action instead of being sent to the
+remote VNC server.
+
+Use '\fB\-escape\fR default' for the default modifier sequence.
+(Unix: Alt_L,Super_L and MacOSX: Control_L,Meta_L)
+
+Here are the 'Escape Keys: Help+Set' instructions from the Popup:
+
+Escape Keys:  Enter a comma separated list of modifier keys to be the 'escape
+sequence'.  When these keys are held down, the next keystroke is
+interpreted locally to invoke a special action instead of being sent to
+the remote VNC server.  In other words, a set of 'Hot Keys'.
+
+Here is the list of local key mappings to special actions:
+
+r: refresh desktop  b: toggle bell  c: toggle full-color
+
+f: file transfer    x: x11cursor    z: toggle Tight/ZRLE
+
+l: full screen      g: graball      e: escape keys dialog
+
+s: scale dialog     +: scale up (=) -: scale down (_)
+
+t: text chat                        a: alphablend cursor
+
+V: toggle viewonly  Q: quit viewer  123456: UltraVNC scale 1/n
+
+Arrow keys: pan the viewport about 10% for each keypress.
+
+PageUp/PageDown: pan the viewport by a screenful vertically.
+
+Home/End: pan the viewport by a screenful horizontally.
+
+KeyPad Arrows: pan the viewport by 1 pixel for each keypress.
+
+Dragging the Mouse with Button1 pressed also pans the viewport.
+
+Clicking Mouse Button3 brings up the Popup Menu.
+
+The above mappings are \fBalways\fR active in ViewOnly mode, unless you set
+the Escape Keys value to 'never'.
+
+x11vnc -appshare hot-keys:  x11vnc has a simple application sharing mode
+that enables the viewer-side to move, resize, or raise the remote toplevel
+windows.  To enable it, hold down Shift + the Escape Keys and press these:
+
+Arrow keys: move the remote window around in its desktop.
+
+PageUp/PageDn/Home/End:  resize the remote window.
+
++/-: raise or lower the remote window.
+
+M or Button1 move win to local position;  D or Button3: delete remote win.
+
+If the Escape Keys value below is set to 'default' then a default list of
+of modifier keys is used.  For Unix it is: Alt_L,Super_L and for MacOSX it
+is Control_L,Meta_L.  Note: the Super_L key usually has a Windows(TM) Flag
+on it.  Also note the _L and _R mean the key is on the LEFT or RIGHT side
+of the keyboard.
+
+On Unix   the default is Alt and Windows keys on Left side of keyboard.
+On MacOSX the default is Control and Command keys on Left side of keyboard.
+
+Example: Press and hold the Alt and Windows keys on the LEFT side of the
+keyboard and then press 'c' to toggle the full-color state.  Or press 't'
+to toggle the ultravnc Text Chat window, etc.
+
+To use something besides the default, supply a comma separated list (or a
+single one) from: Shift_L Shift_R Control_L Control_R Alt_L Alt_R Meta_L
+Meta_R Super_L Super_R Hyper_L Hyper_R or Mode_switch.

+ Type B:Non liner quantization filter.
+
+ Coefficients have Gaussian curve and smaller value which is
+ large part of coefficients isn't more important than larger value.
+ So, I use filter of Non liner quantize/dequantize table.
+ In general, Non liner quantize formula is explained as following.
+
+    y=f(x)   = sign(x)*round( ((abs(x)/(2^7))^ r   )* 2^(bo-1) )*2^(8-bo)
+    x=f-1(y) = sign(y)*round( ((abs(y)/(2^7))^(1/r))* 2^(bi-1) )*2^(8-bi)
+ ( r:power coefficient  bi:effective MSB in input  bo:effective MSB in output )
+
+   r < 1.0 : Smaller value is more important than larger value.
+   r > 1.0 : Larger value is more important than smaller value.
+   r = 1.0 : Liner quantization which is same with EZW style.
+
+ r = 0.75 is famous non liner quantization used in MP3 audio codec.
+ In contrast to audio data, larger value is important in wavelet coefficients.
+ So, I select r = 2.0 table( quantize is x^2, dequantize sqrt(x) ).
+
+ As compared with EZW style liner quantization, this filter tended to be
+ more sharp edge and be more compression rate but be more blocking noise and be less quality.
+ Especially, the surface of graphic objects has distinguishable noise in middle quality mode.
+
+ We need only quantized-dequantized(filtered) value rather than quantized value itself
+ because all values are packed or palette-lized in later ZRLE section.
+ This lead us not to need to modify client decoder when we change
+ the filtering procedure in future.
+ Client only decodes coefficients given by encoder.
