Format syntax:
  A format is a string that will be output for each package. The format
  can include the standard escape sequences \n (newline), \r (carriage
  return) or \\ (plain backslash). Package information can be included
  by inserting variable references to package fields using the ${var[;width]}
  syntax. Fields will be right-aligned unless the width is negative in which
  case left alignment will be used.

Use 'dpkg' to install and remove packages from your system, or
'apt' or 'aptitude' for user-friendly package management. Packages
unpacked using 'dpkg-deb --extract' will be incorrectly installed !
