+      Enter the date of the snapshot you want to use in the form: YYYYMMDD
+      where YYYY is the 4-digit year, MM the 2-digit month and DD the 2-digit
+      day in the month.
+      
+      Please note:
+      - glibc has snapshots done every monday, and only the last ten are kept.
+      - uClibc has daily snapshots, and only the last 30-or-so are kept.
+      
+      So if you want to be able to re-build your toolchain later, you will
+      have to sacve your C library tarball by yourself.
