How to select which packages to download

Hi,

I read the About page, the FAQ and the handbook through chapter 4, and 
was under the impression that I would be able to choose which packages 
got downloaded, built, etc.  I then checked out the 7.0 branch and did 
./scripts/Config.  I chose Generic, Minimalistic and was therefore 
expecting some screen or other mechanism to select which packages I wanted.

I then tried ./scripts/Download -list and it reported it (presumably) 
was going to download 3279 tarballs.  Since I don't want to wait for 
hours and use up GBs of disk space for packages that I'll never build, I 
was reluctant to do a ./script/Download -required without first knowing 
what packages will be downloaded (hopefully not all).  However, when I 
tried, it started downloading packages that I don't need (or want) such 
as dietlibc and embutils.

In addition, when I read that T2 "package configurations usually point 
to the latest packages", I thought that it would still allow one to 
select which package versions one could build with (since many times, 
the latest is not the greatest--particularly in combination with other 
dependent packages).

Is there a way to only select only certain packages and particular 
versions of packages?
