python-apt 0.7.3.1ubuntu4.2 (i386 binary) in ubuntu gutsy

 The apt_pkg Python interface will provide full access to the internal
 libapt-pkg structures allowing Python programs to easily perform a
 variety of functions, such as:
 .
  - Access to the APT configuration system
  - Access to the APT package information database
  - Parsing of Debian package control files, and other files with a
    similar structure
 .
 The included 'aptsources' Python interface provides an abstraction of
 the sources.list configuration on the repository and the distro level.
