+      Normally, crosstool-NG will try to download missing tarballs (or
+      checkout from CVS/SVN...).
+      If you do not have network connectivity when you run crosstool-NG,
+      and some files are missing, it can be a long time before crosstool-NG
+      fails.
+      
+      Saying 'y' here will prevent crosstool-NG from downloading missing
+      files, thus failing early so that you don't get stuck.
