+Waf 1.6
+
+Try to detect if the project directory was relocated, and if it was,
+change the node representing the project directory. Just call:
+
+ waf configure build
+
+Note that if the project directory name changes, the signatures for the tasks using
+files in that directory will change, causing a partial build.
