# IMCOPY -- Copy image(s)
#
# The input images are given by an image template list.  The output
# is either a matching list of images or a directory.
# The number of input images may be either one or match the number of output
# images.  Image sections are allowed in the input images and are ignored
# in the output images.  If the input and output image names are the same
# then the copy is performed to a temporary file which then replaces the
# input image.
