One minor comment is that "automated invisible supervision" would surely
be wrong, as people may, for example, want to install some package by
means other than cygwin setup (e.g., by compiling from the source cvs).
However, a dependence check and a warning to make sure the user knows what
he's doing before installing the packages would be a nice addition.
