repo/git Android/CyanogenMod srouce code

For getting the whole Android/CM rom source code,
1. get the repo first.
2. make sure the git is installed.

1. how to get the repo:
http://source.android.com/source/downloading.html#installing-repo
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
2. how to install git (Ubuntu):
apt-get install git-core git-svn gitk git-gui git-email gnupg

** other tools
sudo apt-get install flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl valgrind

** For Android rom:
repo init -u https://android.googlesource.com/platform/manifest -b android-2.3.1_r1 (the whole build)
** For CM rom:
https://github.com/CyanogenMod/android // Click "Fork" button, and copy the "HTTPS clone URL" for git.
repo init -u git://github.com/CyanogenMod/android.git -b cm-12.0    // Cm12的代码, 基于android5.0

repo init -u git://github.com/CyanogenMod/android.git -b cm-11.0    // Cm11的代码, 基于android4.4, 大于23.4 GB
