Fetching All Source For a Release

If you want to download all of the source for a release, here is a simple procedure using just a shell and darwinbuild (using 9G55 as an example):

1. install darwinbuild
2. mkdir 9G55 && cd 9G55
3. sudo -s
4. darwinbuild -init 9G55
5. for X in $(darwinxref version '*' | cut -d '-' -f 1); do darwinbuild -fetch $X; done
6. mkdir AllSource
7. for X in Sources/*; do tar zxvf $X -C AllSource/; done
