Downloading the files from s3 recursively using boto python.

Just added directory creation part to @j0nes comment

This will download files to current directory and will create directories when needed.

You can download all files in a bucket like this (untested):
from boto.s3.connection import S3Connection
conn = S3Connection('your-access-key','your-secret-key')
bucket = conn.get_bucket('bucket')
for key in bucket.list():
try:
res = key.get_contents_to_filename(key.name)
except:
logging.info(key.name+":"+"FAILED")
Keep in mind that folders in S3 are simply another way of writing the key name and only clients will show this as folders.
