Migrate from S3 to Rackspace Cloud Files
S3 to Rackspace Cloud Files Migration
This script will copy the contents of a S3
bucket to to a Rackspace Cloud Files container.
Author: Tony Landis
License: Do whatever you want with this code
Usage: Just define the S3_* and CF_* settings below before running.
If you have a s3 bucket name with characters that are not
valid for a file name on your system, you will need to change
the tmp_file and mrk_file as well to avoid issues.
