Implement all tags except some customs-related ones. Automatic batch splitting based on global criteria (such as layout file). Invertable DocInfo objects (via ~ to negate an item). Infrastructure to support docinfos that only apply to a second pass (e.g. after address info is known).
========================================================== Package Shipment and Address Verification with ``PyDicia`` ========================================================== PyDicia is a Python interface to endicia.com's postal services client, DAZzle. Using DAZzle's XML interface, PyDicia can be used to print shipping labels, envelopes, postcards and more, with or without prepaid US postage indicia (electronic stamps), as well as doing address verification. In addition to providing a layer of syntax sugar for the DAZzle XML interface, PyDicia provides a novel adaptive interface that lets you smoothly integrate its functions with your application's core types (like invoice, customer, or "packing slip" objects) without subclassing. (This is particularly useful if you are extending a CRM or other database that was written by somebody else.) PyDicia uses the ElementTree, simplegeneric, and DecoratorTools packages, and requires Python 2.4 or higher (due to use of decorators and the ``Decimal`` type).

The default implementation is to raise an error:: >>> from pydicia import iter_docinfo >>> iter_docinfo(27) Traceback (most recent call last): ... NotImplementedError: ('No docinfo producer registered for', <type 'int'>) And for lists and tuples, the default is to yield their contents:: >>> list(iter_docinfo((1, 2, 3))) [1, 2, 3] >>> list(iter_docinfo(['a', 'b'])) ['a', 'b'] This routine is used internally by ``add_to_package()``.
