+ In some instances involing 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.
