- -- If parsing is successful, Project_Id is the project ID

+ -- If parsing is successful, Project is the project ID of the root project
+ -- file; otherwise, Project_Id is set to No_Project. Project_Node_Tree is
+ -- set to the tree (unprocessed) representation of the project file. This
+ -- tree is permanently correct, whereas Project will need to be recomputed
+ -- if the external references change.
