# Tidy up photo filenames in a directory hierachy
#
# In particular this is designed to fix up imports from FAT file systems
# which are in upper case and put them into lower case for sane interactive
# use.
#
# .JPG
# .CR2
#
# files are renamed to the lower case variant.  All image files have their
# permissions corrected.
