/* This file is an index of all APT configuration directives. It should
   NOT actually be used as a real config file, though it is a completely
   valid file.
   
   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 eg,
     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.
