systools:make_relup w/ vanilla erlang system

[Alpar Juttner]

Hi,

If I have an .appup file referring to other versions of the application,
then systools:make_relup needs the corresponding .app files, too.
Therefore those versions of the application should be installed to the
erlang runtime system.

Is is possible to directly specify those .app files for make_relup
instead, so that I can use my vanilla erlang system for creating the
relup file?

Regards,
Alpar
