Getting a drupal site up locally in least time possible with the least dependencies. I want to make this a new command. Just some brainstorming.

drupalsite.sh

# Install Drush
# Install Git
# Install MySQL

# Get drupal codebase
git clone git@github.com:your/repo.git
cd repo

# Create drush alias
$aliases['sitename'] = array(
  'uri' => 'sitename:8888',
  'root' => '/home/user/path/to/site',
  'default-server' => 'sitename:8888',
);

# Edit hosts file.
127.0.0.1  sitename

# Run site-install.  This also creates the database, sets up our sites/default/settings.php and files folder for us.
drush @sitename site-install --db-url=mysql://root:MySqlRootPw@localhost/dbname  

# This runs a lightweight PHP server with tailing error log, making for instantly easy development.
drush @sitename run-server

# Visit your site:
http://sitename:8888
