# Generate HTML demonstrations based on Screenshots Tool and PngWalkTool QC facility.
# The screenshots tool is run, creating a sequence of screenshots. This should be trimmed
# automatically, so that all images are of the same size, and as small as possible.
# The PNGWalk QC tool is turned on, and then "OK/green" images are written to HTML with
# the last comment as the caption to each figure.
