+/* This file is an index of all APT configuration directives.
+   Instead of actual values the option has the type as value.
+   Additional explanations and possible values might be detailed in a comment.
+
+   Most of the options have sane default values,
+   unless you have specific needs you should NOT include arbitrary
+   items in a custom configuration.
+
+   In some instances involving filenames it is possible to set the default
+   directory when the path is evaluated. This means you can use relative
+   paths within the sub scope.
+
+   The configuration directives are specified in a tree with {} designating
+   a subscope relative to the tag before the {}. You can further specify
+   a subscope using scope notation e.g.,
+     APT::Architecture "i386";
+   This is prefixed with the current scope. Scope notation must be used
+   if an option is specified on the command line with -o.
+
+   The most complex type is perhaps <LIST>:
+      APT::Architectures "<LIST>";
+   In configuration files it usually appears as a subscope of its own like:
+      APT::Architectures { "amd64"; "i386"; };
+   but the same can be achieved with (needed for commandline)
+      APT::Architectures "amd64,i386";
+   which overrides the values in the scope notation.
+
+   See apt.conf manpage for a detailed description of many common options
+   and the syntax of configuration files and commandline options!
