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 !
