+Python S3 Examples
+==================
+
+Creating a Connection
+---------------------
+
+This creates a connection so that you can interact with the server.
+
+.. code-block:: python
+
+	import boto
+	import boto.s3.connection
+	access_key = 'put your access key here!'
+	secret_key = 'put your secret key here!'
+
+	conn = boto.connect_s3(
+		aws_access_key_id = access_key,
+		aws_secret_access_key = secret_key,
+		host = 'objects.dreamhost.com',
+                #is_secure=False,               # uncomment if you are not using ssl
+		calling_format = boto.s3.connection.OrdinaryCallingFormat(),
+		)
+
+
+Listing Owned Buckets
+---------------------
+
+This gets a list of Buckets that you own.
+This also prints out the bucket name and creation date of each bucket.
+
+.. code-block:: python
+
+	for bucket in conn.get_all_buckets():
+		print "{name}\t{created}".format(
+			name = bucket.name,
+			created = bucket.creation_date,
+		)
+
+The output will look something like this::
+
+   mahbuckat1	2011-04-21T18:05:39.000Z
+   mahbuckat2	2011-04-21T18:05:48.000Z
+   mahbuckat3	2011-04-21T18:07:18.000Z
+
+
+Creating a Bucket
+-----------------
+
+This creates a new bucket called ``my-new-bucket``
+
+.. code-block:: python
+
+	bucket = conn.create_bucket('my-new-bucket')
+
+
+Listing a Bucket's Content
+--------------------------
+
+This gets a list of objects in the bucket.
+This also prints out each object's name, the file size, and last
+modified date.
+
+.. code-block:: python
+
+	for key in bucket.list():
+		print "{name}\t{size}\t{modified}".format(
+			name = key.name,
+			size = key.size,
+			modified = key.last_modified,
+			)
+
+The output will look something like this::
+
+   myphoto1.jpg	251262	2011-08-08T21:35:48.000Z
+   myphoto2.jpg	262518	2011-08-08T21:38:01.000Z
+
+
+Deleting a Bucket
+-----------------
+
+.. note::
+
+   The Bucket must be empty! Otherwise it won't work!
+
+.. code-block:: python
+
+	conn.delete_bucket(bucket.name)
+
+
+Forced Delete for Non-empty Buckets
+-----------------------------------
+
+.. attention::
+
+   not available in python
+
+
+Creating an Object
+------------------
+
+This creates a file ``hello.txt`` with the string ``"Hello World!"``
+
+.. code-block:: python
+
+	key = bucket.new_key('hello.txt')
+	key.set_contents_from_string('Hello World!')
+
+
+Change an Object's ACL
+----------------------
+
+This makes the object ``hello.txt`` to be publicly readable, and
+``secret_plans.txt`` to be private.
+
+.. code-block:: python
+
+	hello_key = bucket.get_key('hello.txt')
+	hello_key.set_canned_acl('public-read')
+	plans_key = bucket.get_key('secret_plans.txt')
+	plans_key.set_canned_acl('private')
+
+
+Download an Object (to a file)
+------------------------------
+
+This downloads the object ``perl_poetry.pdf`` and saves it in
+``/home/larry/documents/``
+
+.. code-block:: python
+
+	key = bucket.get_key('perl_poetry.pdf')
+	key.get_contents_to_filename('/home/larry/documents/perl_poetry.pdf')
+
+
+Delete an Object
+----------------
+
+This deletes the object ``goodbye.txt``
+
+.. code-block:: python
+
+	bucket.delete_key('goodbye.txt')
+
+
+Generate Object Download URLs (signed and unsigned)
+---------------------------------------------------
+
+This generates an unsigned download URL for ``hello.txt``. This works
+because we made ``hello.txt`` public by setting the ACL above.
+This then generates a signed download URL for ``secret_plans.txt`` that
+will work for 1 hour. Signed download URLs will work for the time
+period even if the object is private (when the time period is up, the
+URL will stop working).
+
+.. code-block:: python
+
+	hello_key = bucket.get_key('hello.txt')
+	hello_url = hello_key.generate_url(0, query_auth=False, force_http=True)
+	print hello_url
+
+	plans_key = bucket.get_key('secret_plans.txt')
+	plans_url = plans_key.generate_url(3600, query_auth=True, force_http=True)
+	print plans_url
+
+The output of this will look something like::
+
+   http://objects.dreamhost.com/my-bucket-name/hello.txt
+   http://objects.dreamhost.com/my-bucket-name/secret_plans.txt?Signature=XXXXXXXXXXXXXXXXXXXXXXXXXXX&Expires=1316027075&AWSAccessKeyId=XXXXXXXXXXXXXXXXXXX
