# Convert all of the files in the SIVAL collection to
# ppm files that can be used as FakeCamera images in
# Pyro.

# Each set of ppm images appears within its own sub-directory.
# The characters before the first _ are used to define the
# sub-directory name. For example, for the CokeCan images all
# images starting with fluor1 appear in the CokeCan/fluor1/
# directory in the FakeCameras Directory.
