Looks at a directory hive, finds .JPGs with EXIF info, and sorts them in a new directory structure by camera model, year, month, and optionally, date. Imports EXIF.py and dirwalk.py in addition to standard Python modules.

Filename: PhotoLibrarian.py
Author: Alex Harden
Release Date: 2007-03-26
Description: Iterates through a directory tree, reading the EXIF data from each JPG. Parses the
date/time from EXIF data, and copies the photo using the date/time value into a
new camera/year/month-based tree. Additional sort by day available.
