<deb> is the filename of a Debian format archive.
<cfile> is the name of an administrative file component.
<cfield> is the name of a field in the main `control' file.

Options:
–showformat= Use alternative format for --show.
-v, --verbose Enable verbose output.
-D, --debug Enable debugging output.
–deb-format= Select archive format.
Allowed values: 0.939000, 2.0 (default).
–old Legacy alias for ‘–deb-format=0.939000’.
–new Legacy alias for ‘–deb-format=2.0’.
–nocheck Suppress control file check (build bad
packages).
-z# Set the compression level when building.
-Z Set the compression type used when building.
Allowed types: gzip, xz, bzip2, none.
-S Set the compression strategy when building.
Allowed values: none; extreme (xz);
filtered, huffman, rle, fixed (gzip).

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 !
