-- 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)
