# slightly modified by betso

#			so use cpexif here which compiles like a charm :)
#	to run with sh (bash is not default in *BSD!).
# -----------------------------------------------------------------------
#
# 1. Makes all filenames lowercase.
# 2. Changes the _ in the D70s-filenames to a chosen number between 0 and 9
# 3. Runs dcraw in cheapest mode for preview-jpg-pictures
# 4. Extracts exif-tags from nef-files and write them to preview-jpg-pictures.
# 5. Remove Orientation-exif-tag as dcraw has already rotated the picture.
#
# This script performs its operations on all nef-files present
# in current directory.
