yann@852:       Enter the date of the snapshot you want to use in the form: YYYYMMDD
yann@852:       where YYYY is the 4-digit year, MM the 2-digit month and DD the 2-digit
yann@852:       day in the month.
yann@852:       
yann@852:       Please note:
yann@852:       - glibc has snapshots done every monday, and only the last ten are kept.
yann@852:       - uClibc has daily snapshots, and only the last 30-or-so are kept.
yann@852:       
yann@852:       So if you want to be able to re-build your toolchain later, you will
yann@852:       have to save your C library tarball by yourself.
