+The identity tool helps create and manage keys and blessings that are used for
+identification in veyron.
+
+Usage:
+   identity <command>
+
+The identity commands are:
+   print       Print out information about the provided identity
+   generate    Generate an identity with a newly minted private key
+   bless       Bless another identity with your own
+   seekblessing Seek a blessing from the default veyron identity provider
+   help        Display help for commands or topics
+Run "identity help [command]" for command usage.
+
+The global flags are:
+   -alsologtostderr=true: log to standard error as well as files
+   -log_backtrace_at=:0: when logging hits line file:N, emit a stack trace
+   -log_dir=: if non-empty, write log files to this directory
+   -logtostderr=false: log to standard error instead of files
+   -max_stack_buf_size=4292608: max size in bytes of the buffer to use for logging stack traces
+   -stderrthreshold=2: logs at or above this threshold go to stderr
+   -v=0: log level for V logs
+   -vmodule=: comma-separated list of pattern=N settings for file-filtered logging
+   -vv=0: log level for V logs
+
+Identity Print
+
+Print dumps out information about the identity encoded in the provided file,
+or if no filename is provided, then the identity that would be used by binaries
+started in the same environment.
+
+Usage:
+   identity print [<file>]
+
+<file> is the path to a file containing a base64-encoded, VOM encoded identity,
+typically obtained from this tool. - is used for STDIN and an empty string
+implies the identity encoded in the environment.
+
+Identity Generate
+
+Generate a new private key and create an identity that binds <name> to
+this key.
+
+Since the generated identity has a newly minted key, it will be typically
+unusable at other veyron services as those services have placed no trust
+in this key. In such cases, you likely want to seek a blessing for this
+generated identity using the 'bless' command.
+
+Usage:
+   identity generate [<name>]
+
+<name> is the name to bind the newly minted private key to. If not specified,
+a name will be generated based on the hostname of the machine and the name of
+the user running this command.
+
+Identity Bless
+
+Bless uses the identity of the tool (either from an environment variable or
+explicitly specified using --with) to bless another identity encoded in a
+file (or STDIN). No caveats are applied to this blessing other than expiration,
+which is specified with --for.
+
+The output consists of a base64-vom encoded security.PrivateID or security.PublicID,
+depending on what was provided as input.
+
+For example, if the tool has an identity veyron/user/device, then
+bless /tmp/blessee batman
+will generate a blessing with the name veyron/user/device/batman
+
+The identity of the tool can be specified with the --with flag:
+bless --with /tmp/id /tmp/blessee batman
+
+Usage:
+   identity bless [flags] <file> <name>
+
+<file> is the name of the file containing a base64-vom encoded security.PublicID
+or security.PrivateID
+
+<name> is the name to use for the blessing.
+
+The bless flags are:
+   -for=8760h0m0s: Expiry time of blessing (defaults to 1 year)
+   -with=: Path to file containing identity to bless with (or - for STDIN)
+
+Identity Seekblessing
+
+Seeks a blessing from a default, hardcoded Veyron identity provider which
+requires the caller to first authenticate with Google using OAuth. Simply
+run the command to see what happens.
+
+The blessing is sought for the identity that this tool is using. An alternative
+can be provided with the --for flag.
+
+Usage:
+   identity seekblessing [flags]
+
+The seekblessing flags are:
+   -for=: Path to file containing identity to bless (or - for STDIN)
+   -from=https://proxy.envyor.com:8125/google: URL to use to begin the seek blessings process
+
+Identity Help
+
+Help with no args displays the usage of the parent command.
+Help with args displays the usage of the specified sub-command or help topic.
+"help ..." recursively displays help for all commands and topics.
+
+Usage:
+   identity help [flags] [command/topic ...]

-
-The namespace roots are set from environment variables that have a name
-starting with NAMESPACE_ROOT, e.g. NAMESPACE_ROOT, NAMESPACE_ROOT_2,
-NAMESPACE_ROOT_GOOGLE, etc.
-
-Usage:
-   namespace <command>
-
-The namespace commands are:
-   glob        Returns all matching entries from the namespace
-   mount       Adds a server to the namespace
-   unmount     Removes a server from the namespace
-   resolve     Translates a object name to its object address(es)
-   resolvetomt Finds the address of the mounttable that holds an object name
-   unresolve   Returns the rooted object names for the given object name
-   help        Display help for commands
-
-The global flags are:
-   -alsologtostderr=true: log to standard error as well as files
-   -log_backtrace_at=:0: when logging hits line file:N, emit a stack trace
-   -log_dir=: if non-empty, write log files to this directory
-   -logtostderr=false: log to standard error instead of files
-   -max_stack_buf_size=4292608: max size in bytes of the buffer to use for logging stack traces
-   -stderrthreshold=2: logs at or above this threshold go to stderr
-   -v=0: log level for V logs
-   -vmodule=: comma-separated list of pattern=N settings for file-filtered logging
-   -vv=0: log level for V logs
-
-Namespace Glob
-
-Returns all matching entries from the namespace.
-
-Usage:
-   namespace glob <pattern>
-
-<pattern> is a glob pattern that is matched against all the names below the
-specified mount name.
-
-Namespace Mount
-
-Adds server <server> to the namespace with name <name>.
-
-Usage:
-   namespace mount <name> <server> <ttl>
-
-<name> is the name to add to the namespace.
-<server> is the object address of the server to add.
-<ttl> is the TTL of the new entry. It is a decimal number followed by a unit
-suffix (s, m, h). A value of 0s represents an infinite duration.
-
-Namespace Unmount
-
-Removes server <server> with name <name> from the namespace.
-
-Usage:
-   namespace unmount <name> <server>
-
-<name> is the name to remove from the namespace.
-<server> is the object address of the server to remove.
-
-Namespace Resolve
-
-Translates a object name to its object address(es).
-
-Usage:
-   namespace resolve <name>
-
-<name> is the name to resolve.
-
-Namespace Resolvetomt
-
-Finds the address of the mounttable that holds an object name.
-
-Usage:
-   namespace resolvetomt <name>
-
-<name> is the name to resolve.
-
-Namespace Unresolve
-
-Returns the rooted object names for the given object name.
-
-Usage:
-   namespace unresolve <name>
-
-<name> is the object name to unresolve.
-
-Namespace Help
-
-Help displays usage descriptions for this command, or usage descriptions for
-sub-commands.
-
-Usage:
-   namespace help [flags] [command ...]
-
-[command ...] is an optional sequence of commands to display detailed usage.
-The special-case "help ..." recursively displays help for all commands.
-
-The help flags are:
-   -style=text: The formatting style for help output, either "text" or "godoc".
