-- Perform consistency and semantic checks on a project, starting from the
-- project tree parsed from the .gpr file. This procedure interprets the
-- various case statements in the project based on the current environment
-- variables (the "scenario").
-- After checking the validity of the naming scheme, it searches for all
-- the source files of the project.
-- The result of this procedure is a filled data structure for Project_Id
-- which contains all the information about the project. This information
-- is only valid while the scenario variables are preserved.
-- If the current mode is Ada_Only, this procedure will only search Ada
-- sources; but in multi_language mode it will look for sources for all the
-- supported languages.
--
-- If Report_Error is null , use the standard error reporting mechanism
-- (Errout). Otherwise, report errors using Report_Error.
--
-- Current_Dir is for optimization purposes only, avoiding system calls to
-- query it.
--
-- When_No_Sources indicates what should be done when no sources of a
-- language are found in a project where this language is declared.
