NAME
       apt-config - APT Configuration Query program

SYNOPSIS
       apt-config [-hv] [-o=config string] [-c=file] {[shell] | [dump]}

DESCRIPTION
       apt-config is an internal program used by various portions of the APT
       suite to provide consistent configurability. It accesses the main
       configuration file /etc/apt/apt.conf in a manner that is easy to use by
       scripted applications.

       Unless the -h, or --help option is given one of the commands below must
       be present.

       shell
	  shell is used to access the configuration information from a shell
	  script. It is given pairs of arguments, the first being a shell
	  variable and the second the configuration value to query. As output
	  it lists a series of shell assignments commands for each present
	  value. In a shell script it should be used like:

	     OPTS="-f"
	     RES=apt-config shell OPTS MyApp::options
	     eval $RES
	  This will set the shell environment variable $OPTS to the value of
	  MyApp::options with a default of -f.

	  The configuration item may be postfixed with a /[fdbi]. f returns
	  file names, d returns directories, b returns true or false and i
	  returns an integer. Each of the returns is normalized and verified
	  internally.

       dump
	  Just show the contents of the configuration space.

OPTIONS
       All command line options may be set using the configuration file, the
       descriptions indicate the configuration option to set. For boolean
       options you can override the config file by using something like
       -f-,--no-f, -f=no or several other variations.

       -h, --help
	  Show a short usage summary.

       -v, --version
	  Show the program version.

       -c, --config-file
	  Configuration File; Specify a configuration file to use. The program
	  will read the default configuration file and then this configuration
	  file. See apt.conf(5) for syntax information.

       -o, --option
	  Set a Configuration Option; This will set an arbitary configuration
	  option. The syntax is -o Foo::Bar=bar.
