gnatstub creates body stubs, that is, empty but compilable bodies for library unit declarations.
Note: to invoke
gnatstub with a project file, use the
driver (see The GNAT Driver and Project Files).
To create a body stub, gnatstub has to compile the library unit declaration. Therefore, bodies can be created only for legal library units. Moreover, if a library unit depends semantically upon units located outside the current directory, you have to provide the source search path when calling gnatstub, see the description of gnatstub switches below.
