pyShipping provides connections to interface with shipping companies and to transport shipping related information.

• package - shipping/cargo related calculations based on a unit of shipping (box, crate, package), includes a bin packing implementation in pure Python
• sendung - defines an abstract shippment (Sendung), with packages and calculations based on that
• addressvalidation - check if an address is valid
• carriers.dpd - calculation of DPD/Georoutes routing data and labels. Included tables are for shippments from Wuppertal but it should work with all other german routing tables.
• fortras - tools for reading and writing Fortras messages. Fortras is a EDI standard for logistics related information somewhat common in Germany. See Wikipedia for further enlightenment

It also comes with the only python based 3D Bin Packing implementation I'm aware of. The Algorithm has sufficient performance to be used in everyday shipping and warehousing applications.
