package Prj.Env is
procedure Initialize (In_Tree : Project_Tree_Ref);
-- Initialize global components relative to environment variables
procedure Print_Sources (In_Tree : Project_Tree_Ref);
-- Output the list of sources, after Project files have been scanned
procedure Create_Mapping (In_Tree : Project_Tree_Ref);
-- Create in memory mapping from the sources of all the projects (in body
-- of package Fmap), so that Osint.Find_File will find the correct path
-- corresponding to a source.

-- template of Language in the Project, put the mapping of its file
-- name and path name in this file.
--
-- Implementation note: we pass a language name, not a language_index here,
-- since the latter would have to match exactly the index of that language
-- for the specified project, and that is not information available in
-- buildgpr.adb.

--
-- If Full_Path is False (the default), the simple file name is returned.
