        Expressive syntax for working with binary data formats and network
        protocols.  Like the :py:mod:`struct` module, but with a more readable
        syntax, especially if your format has:
        
        * Length-prefixed variable-length byte sequences or strings
        * Count-prefixed variable-count repeated fields
        * Terminated (null or otherwise) strings
        * String encodings
        * Numbers which represent enumeration members
        
        Example::
        
          tcp = ezstruct.Struct(
              "NET_ENDIAN",
              ezstruct.Field("UINT16", name="sport"),
              ezstruct.Field("UINT16", name="dport"),
              ezstruct.Field("UINT32", name="seqno"),
              ezstruct.Field("UINT32", name="ackno"),
              ezstruct.Field("UINT16",
                             name="flags",
                             value_transform=ezstruct.FieldTransform(
        		         pack_flags_bitfield,
        			 unpack_flags_bitfield)),
              ezstruct.Field("UINT16", name="window_size"),
              ezstruct.Field("UINT16", name="checksum"),
              ezstruct.Field("UINT16", name="urg"),
              ezstruct.Field("BYTES",
                             name="options",
        		     default_pack_value={},
        		     length=lambda data: data["offset"] - 5,
        		     value_transform=ezstruct.FieldTransform(
                                 pack_and_pad_options,
        			 unpack_options)))
        
          header_data = {"sport": 123,
                         "dport": 456,
                         "seqno": 1,
                         "ackno": 0,

        		 "checksum": 0,
        		 "urg": 0}
          header_bytes = tcp.pack_bytes(header_data)
          assert tcp.unpack_bytes(header_bytes) == header_data
