python-deb822 0.2ubuntu1 (i386 binary) in ubuntu gutsy

 deb822 abstractifies the RFC822 format used in Debian's control files. You
 can use a deb822 object like a Python dictionary, referring to control fields
 as dictionary keys.
 .
 deb822 also has some convenient features that are specific to Debian's .dsc
 and .changes files. For example, it knows about special fields that contain
 whitespace separated sub-fields, and provides named access to them. For
 example, the "Files" field in Source packages, which has three subfields, or
 "Files" in .changes files, which has five.
