automatically starts up a STUNNEL SSL tunnel for SSL connections to
[1]x11vnc (or any other VNC Server also running an SSL tunnel, such as
STUNNEL, at their end), and then launches the TightVNC Viewer. The

a profile called "globals" that has some settings
you use often, then just supply "Include: globals"
to have them applied.
You may supply a comma or space separated list of
templates to include. They can be full path names or
basenames relative to the profiles directory. You do
not need to supply the .vnc suffix. The non-default
settings in them will be applied first, and then any
values then in the loaded Profile will override them.
Note: On Windows since the TightVNC Viewer will save
its own settings in the registry, some unexpected
behavior is possible because the viewer is nearly
always directed to the VNC host "localhost:30". E.g. if
you specify "View Only" in this gui once but not next
time the Windows VNC Viewer may remember the setting.
Unfortunately there is not a /noreg option for the Viewer.
