#
# ssvnc_cmd:
#
# A wrapper that calls ss_vncviewer to use the enhanced TightVNC viewer.
#
# The enhanced TightVNC viewer features are:
#
# - SSL support for connections using the co-bundled stunnel program.
# - rfbNewFBSize VNC support (screen resizing)
# - cursor alphablending with x11vnc at 32bpp
# - xgrabserver support for fullscreen mode (for old window mgrs)
#
#
# Your platform (e.g. Linux.i686) is autodetected and enhanced
# vncviewer and stunnel binaries for it are used (see the ./bin directory).
#
# See the build.unix script if your platform is not in this package.
# You can also set the env. var. UNAME=os.arch to any "os.arch" you want
# to override the autodetetion.
#
# Usage:
#
# ssvnc_cmd [ss_vncviewer-args] hostname:N [vncviewer-args]
#
# if, instead, this script is named "tightvncviewer" it calls the
# vncviewer directly and must be invoked as:
#
# tightvncviewer [vncviewer-args] hostname:N
#
# In both cases, "hostname:N" is the host and VNC display to connect to,
# e.g. snoopy:0
#
# See the script util/ss_vncviewer for details about its arguments:
#
# -verify pemfile
# -mycert pemfile
# -proxy phost:pport
# -alpha
# -grab
#
# N.B. if this script is named "tightvncviewer" the vncviewer is called
# directly, and there won't be any SSL or SSH encryption tunnels.
#
# If the *very first* argument is "-cotvnc" then it is assumed you are on
# Darwin and want to run the Chicken of the VNC viewer via our wrapper.
#
#
# See the TightVNC viewer documentation for on its cmdline arguments.
#
# For convenience, here is the current (7/2006) TightVNC viewer -help output:
#
# TightVNC viewer version 1.3dev5
#
# Usage: vncviewer [<OPTIONS>] [<HOST>][:<DISPLAY#>]
# vncviewer [<OPTIONS>] [<HOST>][::<PORT#>]
# vncviewer [<OPTIONS>] -listen [<DISPLAY#>]
# vncviewer -help
#
# <OPTIONS> are standard Xt options, or:
# -via <GATEWAY>
# -shared (set by default)
# -noshared
# -viewonly
# -fullscreen
# -noraiseonbeep
# -passwd <PASSWD-FILENAME> (standard VNC authentication)
# -user <USERNAME> (Unix login authentication)
# -encodings <ENCODING-LIST> (e.g. "tight copyrect")
# -bgr233
# -owncmap
# -truecolour
# -depth <DEPTH>
# -compresslevel <COMPRESS-VALUE> (0..9: 0-fast, 9-best)
# -quality <JPEG-QUALITY-VALUE> (0..9: 0-low, 9-high)
# -nojpeg
# -nocursorshape
# -x11cursor
# -autopass
#
# Option names may be abbreviated, e.g. -bgr instead of -bgr233.
# See the manual page for more information.
#
# Note: the enhanced tightvnc viewer (SSVNC) has many more options, run
# this script as "ssvnc_cmd Vnc://a:0 -help" or "tightvncviewer -help"
# to seem them.
