-<B>BUCKET NAME REQUIREMENTS</B>
-  Google Cloud Storage has a single namespace, so you will not be allowed
-  to create a bucket with a name already in use by another user. You can,
-  however, carve out parts of the bucket name space corresponding to your
-  company's domain name (see "DOMAIN NAMED BUCKETS").
-
-  Bucket names must conform to standard DNS naming conventions. This is
-  because a bucket name can appear in a DNS record as part of a CNAME
-  redirect. In addition to meeting DNS naming requirements, Google Cloud
-  Storage imposes other requirements on bucket naming. At a minimum, your
-  bucket names must meet the following requirements:
-
-    - Bucket names must contain only lowercase letters, numbers, dashes (-), and
-      dots (.).
-
-    - Bucket names must start and end with a number or letter.
-
-    - Bucket names must contain 3 to 63 characters. Names containing dots can
-      contain up to 222 characters, but each dot-separated component can be
-      no longer than 63 characters.
-
-    - Bucket names cannot be represented as an IPv4 address in dotted-decimal
-      notation (for example, 192.168.5.4).
-
-    - Bucket names cannot begin with the "goog" prefix.
-
-    - For DNS compliance, you should not have a period adjacent to another
-      period or dash. For example, ".." or "-." or ".-" are not acceptable.
-
-
-<B>OBJECT NAME REQUIREMENTS</B>
-  Object names can contain any sequence of Unicode characters, of length 1-1024
-  bytes when UTF-8 encoded. Object names must not contain CarriageReturn,
-  CarriageReturnLineFeed, or the XML-disallowed surrogate blocks (xFFFE
-  or xFFFF).
-
-  We highly recommend that you avoid using control characters that are illegal
-  in XML 1.0 in your object names. These characters will cause XML listing
-  issues when you try to list your objects.
-
-
-<B>DOMAIN NAMED BUCKETS</B>
-  You can carve out parts of the Google Cloud Storage bucket name space
-  by creating buckets with domain names (like "example.com").
-
-  Before you can create a bucket name containing one or more '.' characters,
-  the following rules apply:
-  - If the name is a syntactically valid DNS name ending with a
-    currently-recognized top-level domain (such as .com), you will be required
-    to verify domain ownership.
-  - Otherwise you will be disallowed from creating the bucket.
-
-  If your project needs to use a domain-named bucket, you need to have
-  a team member both verify the domain and create the bucket. This is
-  because Google Cloud Storage checks for domain ownership against the
-  user who creates the bucket, so the user who creates the bucket must
-  also be verified as an owner or manager of the domain.
-
-  To verify as the owner or manager of a domain, use the Google Webmaster
-  Tools verification process. The Webmaster Tools verification process
-  provides three methods for verifying an owner or manager of a domain:
-
-  1. Adding a special Meta tag to a site's homepage.
-  2. Uploading a special HTML file to a site.
-  3. Adding a DNS TXT record to a domain's DNS configuration.
-
-  Meta tag verification and HTML file verification are easier to perform and
-  are probably adequate for most situations. DNS TXT record verification is
-  a domain-based verification method that is useful in situations where a
-  site wants to tightly control who can create domain-named buckets. Once
-  a site creates a DNS TXT record to verify ownership of a domain, it takes
-  precedence over meta tag and HTML file verification. For example, you might
-  have two IT staff members who are responsible for managing your site, called
-  "example.com." If they complete the DNS TXT record verification, only they
-  would be able to create buckets called "example.com", "reports.example.com",
-  "downloads.example.com", and other domain-named buckets.
-
-  Site-Based Verification
-
-  If you have administrative control over the HTML files that make up a site,
-  you can use one of the site-based verification methods to verify that you
-  control or own a site. When you do this, Google Cloud Storage lets you
-  create buckets representing the verified site and any sub-sites - provided
-  nobody has used the DNS TXT record method to verify domain ownership of a
-  parent of the site.
-
-  As an example, assume that nobody has used the DNS TXT record method to verify
-  ownership of the following domains: abc.def.example.com, def.example.com,
-  and example.com. In this case, Google Cloud Storage lets you create a bucket
-  named abc.def.example.com if you verify that you own or control any of the
-  following sites:
-
-  http://abc.def.example.com
-  http://def.example.com
-  http://example.com
-
-  Domain-Based Verification
-
-  If you have administrative control over a domain's DNS configuration, you can
-  use the DNS TXT record verification method to verify that you own or control a
-  domain. When you use the domain-based verification method to verify that you
-  own or control a domain, Google Cloud Storage lets you create buckets that
-  represent any subdomain under the verified domain. Furthermore, Google Cloud
-  Storage prevents anybody else from creating buckets under that domain unless
-  you add their name to the list of verified domain owners or they have verified
-  their domain ownership by using the DNS TXT record verification method.
-
-  For example, if you use the DNS TXT record verification method to verify your
-  ownership of the domain example.com, Google Cloud Storage will let you create
-  bucket names that represent any subdomain under the example.com domain, such
-  as abc.def.example.com, example.com/music/jazz, or abc.example.com/music/jazz.
-
-  Using the DNS TXT record method to verify domain ownership supersedes
-  verification by site-based verification methods. For example, if you
-  use the Meta tag method or HTML file method to verify domain ownership
-  of http://example.com, but someone else uses the DNS TXT record method
-  to verify ownership of the example.com domain, Google Cloud Storage will
-  not allow you to create a bucket named example.com. To create the bucket
-  example.com, the domain owner who used the DNS TXT method to verify domain
-  ownership must add you to the list of verified domain owners for example.com.
-
-  The DNS TXT record verification method is particularly useful if you manage
-  a domain for a large organization that has numerous subdomains because it
-  lets you control who can create buckets representing those domain names.
-
-  Note: If you use the DNS TXT record verification method to verify ownership of
-  a domain, you cannot create a CNAME record for that domain. RFC 1034 disallows
-  inclusion of any other resource records if there is a CNAME resource record
-  present. If you want to create a CNAME resource record for a domain, you must
-  use the Meta tag verification method or the HTML file verification method.
