tar is short for Tape ARchiver. It's original purpose was to create tape archives, meaning a collection of files (uncompressed). Over time, people came to use it for archiving and compressing into files, since tar can write it's output to STDOUT, which can be piped into a compression program like compress or gzip.
GNU tar now includes an option to skip the shell piping and use gzip or bzip2 directly.

aptitude-create-state-bundle
APTITUDE-CREATE() APTITUDE-CREATE()
NAME
aptitude-create-state-bundle - bundle the current aptitude state
SYNOPSIS
aptitude-create-state-bundle [<options>...] <output-file>
DESCRIPTION
aptitude-create-state-bundle produces a compressed archive storing the files that are required to replicate the current package archive
state. The following files and directories are included in the bundle:
o $HOME/.aptitude
o /var/lib/aptitude
o /var/lib/apt
o /var/cache/apt/*.bin
o /etc/apt
o /var/lib/dpkg/status
The output of this program can be used as an argument to aptitude-run-state-bundle(1).
OPTIONS
--force-bzip2
Override the autodetection of which compression algorithm to use. By default, aptitude-create-state-bundle uses bzip2(1) if it is
available, and gzip(1) otherwise. Passing this option forces the use of bzip2 even if it doesn't appear to be available.
--force-gzip
Override the autodetection of which compression algorithm to use. By default, aptitude-create-state-bundle uses bzip2(1) if it is
available, and gzip(1) otherwise. Passing this option forces the use of gzip even if bzip2 is available.
--help
Print a brief usage message, then exit.
--print-inputs
Instead of creating a bundle, display a list of the files and directories that the program would include if it generated a bundle.
FILE FORMAT
The bundle file is simply a tar(1) file compressed with bzip2(1) or gzip(1), with each of the input directory trees rooted at ".".
