at <http://source.android.com/>, although this version was built from source
code available at <http://packages.ubuntu.com/source/raring/android-tools>;
and you can reproduce this package via the following instructions
(for Ubuntu 13.04 Raring):

1. sudo apt-get build-dep android-tools-adb
2. apt-get source android-tools-adb
3. cd android-tools-4.2.2+git20130218/

4. Apply this patch to debian/makefiles/adb.mk (to link libcrypto statically,
so the executable works on Linux installations with different versions of it):
