manualy uClinux without niosftp.com/pub/uclinux/ tar file

Hi

I have one more question. I work now with UClinux and with the guide on the wiki. It is said that we have to do ./checkout . This script is :

for i in

binutils gcc3 linux-2.6 toolchain-build uClibc elf2flt

insight u-boot uClinux-dist

do

cd $i

git checkout -f

cd ..

done

and is enough easy. In each directory we do git checkout -f. After some research (because i heard speaking about git but i never used it) i found that this command extract the archive located in .git/objects/pack in order to obtain the original sources needed for compiling the toolchain.

Is the content of that packs the original content of each source separately ? (because I try to start with nothing else than source code to build my toolchain)

binutils : http://ftp.gnu.org/gnu/binutils/

gcc3 : http://ftp.gnu.org/gnu/gcc/

linux-2.6 : http://www.kernel.org/

toolchain-build : ?

uClibc : http://www.uclibc.org/

elf2flt : ?

insight : ?

u-boot : ? http://www.denx.de/wiki/u-boot/sourcecode

uClinux-dist : http://www.uclinux.org/

nb : I don't understand the purpose of the "?" directories.
