       apt-config - APT Configuration Query program

       apt-config [--empty] [--format '%f "%v";%n'] [-o=config_string]
		  [-c=config_file] {shell | dump | {-v | --version} |
		  {-h | --help}}

       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
       for scripted applications.

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

	   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 shell assignment commands for each value present. In a
	   shell script it should be used as follows:

	       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

	   Just show the contents of the configuration space.

       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.

	   Include options which have an empty value. This is the default, so
	   use --no-empty to remove them from the output.

       --format '%f "%v";%n'
	   Defines the output of each config option. %t will be replaced with
	   its individual name, %f with its full hierarchical name and %v with
	   its value. Use uppercase letters and special characters in the
	   value will be encoded to ensure that it can e.g. be safely used in
	   a quoted-string as defined by RFC822. Additionally %n will be
	   replaced by a newline, and %N by a tab. A % can be printed by using

       -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. If configuration settings need to be set before
	   the default configuration files are parsed specify a file with the
	   APT_CONFIG environment variable. See apt.conf(5) for syntax

       -o, --option
	   Set a Configuration Option; This will set an arbitrary
	   configuration option. The syntax is -o Foo::Bar=bar.	 -o and
	   --option can be used multiple times to set different options.


       apt-config returns zero on normal operation, decimal 100 on error.
