To get started with Android, you'll need to get familiar with Git and Repo.
To initialize your local repository using the TalonICS trees, use a command like this:
repo init -u git://github.com/IceColdSandwich/android.git -b ics
Then to sync up:
. build/envsetup.sh lunch htc_ace-eng make -j4 lord
but change the script to your installed ccache path
