Simple GIT to lazy copy tmp CakePHP app directory structure:

• change directory to working directory cd newSuperCakePHP
• clone this repository into app/tmp directory git clone --depth 1 --branch master https://github.com/samuelszabo/cakephp-tmp-dir.git app/tmp
• remove .git and readme from app/tmp rm -rf app/tmp/.git app/tmp/README.md
• chmod app/tmp dir chmod -R 777 app/tmp
• voila.. finish.
