-- This package keeps two mappings: from unit names to file names,
-- and from file names to path names.
+--
+-- This mapping is used to communicate between the builder (gnatmake or
+-- gprbuild) and the compiler. The format of this mapping file is the
+-- following:
+-- For each source file, there are three lines in the mapping file:
+-- Unit name with %b or %s added depending on whether it is a body or a spec
+-- This line is omitted for file-based languages
+-- File name
+-- Path name (set to '/' if the file should be ignored in fact, ie for
+-- a Locally_Removed_File in a project)
