1 /* This file is an index of all APT configuration directives. It should
2 NOT actually be used as a real config file, though it is (except for the
3 last line) a completely valid file. Most of the options have sane default
4 values, unless you have specific needs you should NOT include arbitrary
5 items in a custom configuration.
7 In some instances involving filenames it is possible to set the default
8 directory when the path is evaluated. This means you can use relative
9 paths within the sub scope.
11 The configuration directives are specified in a tree with {} designating
12 a subscope relative to the tag before the {}. You can further specify
13 a subscope using scope notation eg,
14 APT::Architecture "i386";
15 This is prefixed with the current scope. Scope notation must be used
16 if an option is specified on the command line with -o.
