Slink CDs.

[shaul]

1) I saw some CD vendors who claim that they ship their CD with a multi-cd 
method. Isn't the multi-cd method part of the official CD ? Is it required 
inspite the inclusion of apt ?
2) Some CD vendors say that their CDs include contrib + non-US + parts of 
non-free. Others only mention non US. However, if the official CD has about 
1150 packages then is it wrong to conclude that any vendor who ships 4 or 5 
CDs with about 2550 packages must have include contrib + non-US + parts of 
non-free ?
