x11vnc is to X Window System what WinVNC is to Windows, i.e. a server\
which serves the current Xwindows desktop via RFB (VNC) protocol\
to the user.\
\
Based on the ideas of x0rfbserver and on LibVNCServer, it has evolved\
into a versatile and performant while still easy to use program.\
\
x11vnc was put together and is (actively ;-) maintained by\
Karl Runge <runge@karlrunge.com>\
