After installed developer tools/Xcode you will lose about 8GB disk space or want to reinstall Xcode ? To uninstall developer tools/Xcode type in the following command in the terminal sudo /Developer/Library/uninstall-devtools –mode=all The system will ask you root password and process will take about 5 mins.

This can go in your .vimrc or in a global location such as /usr/share/vim/vimrc. I would be interested in what other command line and vim users do to improve Snow Leopard. step 1.
