Dear all, I agree with Stefano. The present mechanism is simple and only
thinks that are very general and very core (PW, Modules, install) are
downloaded. Making a distinction between core , second shell, third shell,
half shell, made at somewhere or elsewhere ...  may be even more confusing,
and maybe will bring some issues. Moreover, some 'core' (lets call it
'historical') are very specific (like neb) and used only in particular
applications, why to download them by default? at the moment if a user
wants to use neb, he only needs to type make neb, and that's all, like for
the other 'packages' irrespectively of who, how, when, why and what. boh!
