hxstarplot:  Plot an N-body system in an X environment.

            This is the "hdyn" (kira output) version of xstarplot.
            It contains all of the "dyn" xstarplot functionality
            (and will work with standard dyn data files), but
            includes additional functions specific to the hdyn class.

Options:
            -a    specify viewing axis [1/2/3 = x/y/z]
            -b    allow backward steps (up to 512 frames retained) [no]
            -C    center each frame on the standard system center [no]
            -d    dimensionality of plot [2]
            -D    delay time between frames, in ms [16]
            -e    color by energy [no]
            -f    solid-color stars [true]
            -l/L  specify limits [take from initial data]
            -m    highlight multiple systems [no]
            -o    pipe cin to cout [no]
            -p    point scale mode [0]
            -P    specify point size (relative to axis/30) [1, min = 0.5]
            -r    "reverse video" (black background) [true]
            -s    window size, relative to "standard" 400 pixels [1]
            -t    show tree structure [no]
            -u    highlight unperturbed systems [no]
            -v    verbose mode (echo snap times) [no]

Note:  There appears to be a problem with the X interface on some
       systems that causes xstarplot to crash if too many run-time
       user commands are received in a short space of time (e.g.
       try holding down the ">" key in 3D mode).  Presently, the
       only option is to avoid excessive keystrokes in the graphics
       window...
