DigicaMerge is a commandline tool to merge directories of pictures taken with digital cameras. If you've got a digital camera, your hard disk probably contains many directories full of pictures all named with the same names. This utility allows you to merge such directories' contents into a new directory, and renames all the pictures on the fly, ensuring no filename clash will occur. You can define your own naming scheme, using either a set of predefined variables or any recognized Exif tag which may be present in your pictures, and also specify a pattern to select only certain files.
