-r"""UUID objects (universally unique identifiers) according to RFC 4122.
-
-This module provides immutable UUID objects (class UUID) and the functions
-uuid1(), uuid3(), uuid4(), uuid5() for generating version 1, 3, 4, and 5
-UUIDs as specified in RFC 4122.
-
-If all you want is a unique ID, you should probably call uuid1() or uuid4().
-Note that uuid1() may compromise privacy since it creates a UUID containing
-the computer's network address. uuid4() creates a random UUID.
-
-Typical usage:
-
- >>> import uuid
-
- # make a UUID based on the host ID and current time
- >>> uuid.uuid1()
- UUID('a8098c1a-f86e-11da-bd1a-00112444be1e')
-
- # make a UUID using an MD5 hash of a namespace UUID and a name
- >>> uuid.uuid3(uuid.NAMESPACE_DNS, 'python.org')
- UUID('6fa459ea-ee8a-3ca4-894e-db77e160355e')
-
- # make a random UUID
- >>> uuid.uuid4()
- UUID('16fd2706-8baf-433b-82eb-8c7fada847da')
-
- # make a UUID using a SHA-1 hash of a namespace UUID and a name
- >>> uuid.uuid5(uuid.NAMESPACE_DNS, 'python.org')
- UUID('886313e1-3b8a-5372-9b90-0c9aee199e5d')
-
- # make a UUID from a string of hex digits (braces and hyphens ignored)
- >>> x = uuid.UUID('{00010203-0405-0607-0809-0a0b0c0d0e0f}')
-
- # convert a UUID to a string of hex digits in standard form
- >>> str(x)
- '00010203-0405-0607-0809-0a0b0c0d0e0f'
-
- # get the raw 16 bytes of the UUID
- >>> x.bytes
- '\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f'
-
- # make a UUID from a 16-byte string
- >>> uuid.UUID(bytes=x.bytes)
- UUID('00010203-0405-0607-0809-0a0b0c0d0e0f')

- Converting a UUID to a string with str() yields something in the form
- '12345678-1234-1234-1234-123456789abc'. The UUID constructor accepts
- four possible forms: a similar string of hexadecimal digits, or a
- string of 16 raw bytes as an argument named 'bytes', or a tuple of
- six integer fields (with 32-bit, 16-bit, 16-bit, 8-bit, 8-bit, and
- 48-bit values respectively) as an argument named 'fields', or a single
- 128-bit integer as an argument named 'int'.
-
- UUIDs have these read-only attributes:
-
- bytes the UUID as a 16-byte string
-
- fields a tuple of the six integer fields of the UUID,
- which are also available as six individual attributes
- and two derived attributes:
-
- time_low the first 32 bits of the UUID
- time_mid the next 16 bits of the UUID
- time_hi_version the next 16 bits of the UUID
- clock_seq_hi_variant the next 8 bits of the UUID
- clock_seq_low the next 8 bits of the UUID
- node the last 48 bits of the UUID
-
- time the 60-bit timestamp
- clock_seq the 14-bit sequence number
-
- hex the UUID as a 32-character hexadecimal string
-
- int the UUID as a 128-bit integer
-
- urn the UUID as a URN as specified in RFC 4122
-
- variant the UUID variant (one of the constants RESERVED_NCS,
- RFC_4122, RESERVED_MICROSOFT, or RESERVED_FUTURE)
-
- version the UUID version number (1 through 5, meaningful only
- when the variant is RFC_4122)

+
+This module provides immutable UUID objects (class UUID) and the functions
+uuid1(), uuid3(), uuid4(), uuid5() for generating version 1, 3, 4, and 5
+UUIDs as specified in RFC 4122.
+
+If all you want is a unique ID, you should probably call uuid1() or uuid4().
+Note that uuid1() may compromise privacy since it creates a UUID containing
+the computer's network address. uuid4() creates a random UUID.
+
+Typical usage:
+
+ >>> import uuid
+
+ # make a UUID based on the host ID and current time
+ >>> uuid.uuid1()
+ UUID('a8098c1a-f86e-11da-bd1a-00112444be1e')
+
+ # make a UUID using an MD5 hash of a namespace UUID and a name
+ >>> uuid.uuid3(uuid.NAMESPACE_DNS, 'python.org')
+ UUID('6fa459ea-ee8a-3ca4-894e-db77e160355e')
+
+ # make a random UUID
+ >>> uuid.uuid4()
+ UUID('16fd2706-8baf-433b-82eb-8c7fada847da')
+
+ # make a UUID using a SHA-1 hash of a namespace UUID and a name
+ >>> uuid.uuid5(uuid.NAMESPACE_DNS, 'python.org')
+ UUID('886313e1-3b8a-5372-9b90-0c9aee199e5d')
+
+ # make a UUID from a string of hex digits (braces and hyphens ignored)
+ >>> x = uuid.UUID('{00010203-0405-0607-0809-0a0b0c0d0e0f}')
+
+ # convert a UUID to a string of hex digits in standard form
+ >>> str(x)
+ '00010203-0405-0607-0809-0a0b0c0d0e0f'
+
+ # get the raw 16 bytes of the UUID
+ >>> x.bytes
+ '\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f'
+
+ # make a UUID from a 16-byte string
+ >>> uuid.UUID(bytes=x.bytes)
+ UUID('00010203-0405-0607-0809-0a0b0c0d0e0f')

+ UUID objects are immutable, hashable, and usable as dictionary keys.
+ Converting a UUID to a string with str() yields something in the form
+ '12345678-1234-1234-1234-123456789abc'. The UUID constructor accepts
+ four possible forms: a similar string of hexadecimal digits, or a
+ string of 16 raw bytes as an argument named 'bytes', or a tuple of
+ six integer fields (with 32-bit, 16-bit, 16-bit, 8-bit, 8-bit, and
+ 48-bit values respectively) as an argument named 'fields', or a single
+ 128-bit integer as an argument named 'int'.
+
+ UUIDs have these read-only attributes:
+
+ bytes the UUID as a 16-byte string
+
+ fields a tuple of the six integer fields of the UUID,
+ which are also available as six individual attributes
+ and two derived attributes:
+
+ time_low the first 32 bits of the UUID
+ time_mid the next 16 bits of the UUID
+ time_hi_version the next 16 bits of the UUID
+ clock_seq_hi_variant the next 8 bits of the UUID
+ clock_seq_low the next 8 bits of the UUID
+ node the last 48 bits of the UUID
+
+ time the 60-bit timestamp
+ clock_seq the 14-bit sequence number
+
+ hex the UUID as a 32-character hexadecimal string
+
+ int the UUID as a 128-bit integer
+
+ urn the UUID as a URN as specified in RFC 4122
+
+ variant the UUID variant (one of the constants RESERVED_NCS,
+ RFC_4122, RESERVED_MICROSOFT, or RESERVED_FUTURE)
+
+ version the UUID version number (1 through 5, meaningful only
+ when the variant is RFC_4122)
