Configuration Population

The init method populates the configuration object with defaults compiled into libapt-pkg, from the configuration file /etc/apt/apt.conf (or $APT_CONFIG) and directory /etc/apt/apt.conf.d.

Additional configuration files may be loaded with the read_file and read_dir methods.  The "Dir::Cache::archives" example from the previous page could be defined with:

      Dir "/" {
          Cache "var/cache/apt/" {
              archives "archives/";
          };
      };

The parse_cmdline method sets configuration values based on command line arguments.

An object defining the system is returned by the system method.
