-- Parse project file and all its imported project files and create a tree.
-- Return the node for the project (or Empty_Node if parsing failed). If
-- Always_Errout_Finalize is True, Errout.Finalize is called in all cases,
-- Otherwise, Errout.Finalize is only called if there are errors (but not
-- if there are only warnings). Packages_To_Check indicates the packages
-- where any unknown attribute produces an error. For other packages, an
-- unknown attribute produces a warning. When Store_Comments is True,
-- comments are stored in the parse tree.
--
-- Current_Directory is used for optimization purposes only, avoiding extra
-- system calls.
--
-- Is_Config_File should be set to True if the project represents a config
-- file (.cgpr) since some specific checks apply.
--
-- Target_Name will be used to initialize the default project path, unless
-- In_Tree.Project_Path has already been initialized (which is the
-- recommended use).
--
-- If Implicit_Project is True, the main project file being parsed is
-- deemed to be in the current working directory, even if it is not the
-- case. Implicit_Project is set to True when a tool such as gprbuild is
-- invoked without a project file and is using an implicit project file
-- that is virtually in the current working directory, but is physically
-- in another directory.
