 \module{smtplib} and \module{poplib} which actually send and receive
 messages, the email package has a complete toolset for building or
 decoding complex message structures (including attachments)
 and for implementing internet encoding and header protocols.

 the \module{csv} module supports direct reads and writes in a common
 database format.  Together, these modules and packages greatly simplify
 data interchange between python applications and other tools.
