NAME

       xdaliclock - melting digital clock

SYNOPSIS

       xdaliclock

DESCRIPTION

       The xdaliclock program displays a digital clock; when a digit changes, it melts into its new shape.

       This  program was inspired by the Alto and Macintosh programs of the same name, written by Steve Capps in
       1983 or 1984.

       --version
           Print the version number and exit.

       --root
           Render on the root window instead of opening an application window.

           Render on an existing X11 Window instead of its own window.
