Enter the date of the snapshot you want to use in the form: YYYYMMDD |
| yann@852 | 14 |
where YYYY is the 4-digit year, MM the 2-digit month and DD the 2-digit |
| yann@852 | 15 |
day in the month. |

Please note: |
| yann@852 | 18 |
- glibc has snapshots done every monday, and only the last ten are kept. |
| yann@852 | 19 |
- 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 |
| yann@852 | 22 |
have to save your C library tarball by yourself. |
