Delphi 'Output unit dependency information' - what does it do? -

there option in delphi compiler - 'output unit dependency information' - unsure does, although seems try , set --depends option when application compiled, there no output.

does know does?

autodependency information embeds list of .cpp file's recursively #included headers , timestamps .obj. information used build system rebuild .obj if of #included headers change.

note option "disable autodependency information" - include default. if it's turned off, .objs not contain information , won't automatically rebuilt when headers change.
