40 -- Parse project file and all its imported project files and create a tree.
41 -- Return the node for the project (or Empty_Node if parsing failed). If
42 -- Always_Errout_Finalize is True, Errout.Finalize is called in all cases,
43 -- Otherwise, Errout.Finalize is only called if there are errors (but not
44 -- if there are only warnings). Packages_To_Check indicates the packages
45 -- where any unknown attribute produces an error. For other packages, an
46 -- unknown attribute produces a warning. When Store_Comments is True,
47 -- comments are stored in the parse tree.
49 -- Current_Directory is used for optimization purposes only, avoiding extra
