            Packet

Known Subclasses:

Base packet class, with metaclass magic to generate members from self.__hdr__.

Attributes:
    __hdr__: Packet header should be defined as a list of 
             (name, structfmt, default) tuples.
    __byte_order__: Byte order, can be set to override the default ('>')

Example:
>>> class Foo(Packet):
...   __hdr__ = (('foo', 'I', 1), ('bar', 'H', 2), ('baz', '4s', 'quux'))
...
>>> foo = Foo(bar=3)
>>> foo
Foo(bar=3)
>>> str(foo)
'quux'
>>> foo.bar
3
>>> foo.baz
'quux'
>>> foo.foo = 7
>>> foo.baz = 'whee'
>>> foo
Foo(baz='whee', foo=7, bar=3)
>>> Foo('hello, world!')
Foo(baz=' wor', foo=1751477356L, bar=28460, data='ld!')
