+Link commands support an (optional) extended configuration. In this type of
+configuration, instead of specifying source locations directly, targets are
+mapped to extended configuration dictionaries. These dictionaries map "path" to
+the source path, and specify "force" as true if the file or directory should be
+forcibly linked.
