NAME
marks - puts labels on tv images
SYNOPSIS
marks [sleep=] [cross] [radius=] [point] [echo]
DESCRIPTION
This routine takes in ASCII data from stdin with two
space delimited columns with 'row column' values,
i.e. modified star format.
Similar to that generated by stars
and marks any displayed TV images with a circle.
Marks are generated by exclusive OR with the image and
so if they are executed twice, they disappear.
OPTIONS
cross-marks the positions with small cross instead of circle.
echo-prints out positions.
point-marks the positions with dot.
sleep= sleeps the specified number of milliseconds between marks.
radius= makes circles of the specified size.
