typo3clone is a small bash script to clone TYPO3 v4 from http://git.typo3.org and configure the new clone for contributions through https://review.typo3.org.
The script is inspired by the TYPO3 git contribution walkthrough. It does not set your git username and email though.
Just call ./typo3clone.sh
The script will ask you for your typo3.org username to configure the review workflow. It will then create the clone in ./typo3_src-git/.
The script was tested with git v1.7.9 and requires at least v1.7.8.
Thanks to Steffen Gebert for helping out when I ran into trouble setting up the commit message hooks for the submodules.
