Here is a patch for apt-get so that apt-get source <foo> will also install
build-dependencies of foo, and remove build-conflicts of foo.
I don't really like this patch; comments/suggestions on how to better do
this will be appreciated.
Incidentally, Jason, I checked the patch into the aliencode branch...... not
sure if that's what you wanted.
