+  A JSON object containing members:

+  ``source``
+    A string specifying the path to the source directory, represented
+    with forward slashes.  If the directory is inside the top-level

+    directory (with ``.`` for the top-level source directory itself).
+    Otherwise the path is absolute.
+
+  ``build``
+    A string specifying the path to the build directory, represented
+    with forward slashes.  If the directory is inside the top-level
+    build directory then the path is specified relative to that
