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