cng2jpg

Convert "Complete National Geographic" CNG files to JPG for use under Linux

Basic usage

copying from CD into local hard drive:

cng2jpg.py --src /run/media/_user_/CNG_DISC1/disc1/images --dst ~/CNG/discs/images

convert a hard drive copy

cng2jpg.py --src ~/CNG/discs [--remove]

Use --remove to get rid of .cng files as they are converted, to avoid needing extra 40+Gb of space for both jpg and cng.
