      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 save your C library tarball by yourself.
