       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.
