 1. When you run `drush`, the global Drush is called first and then hands execution to the site-local Drush. This gives you the convenience of running `drush` without specifying the full path to the executable, without sacrificing the safety provided by a site-local Drush.
 2. Optional: Copy the [examples/drush.wrapper](https://github.com/drush-ops/drush/blob/master/examples/drush.wrapper) file to your project root and modify to taste. This is a handy launcher script; add --local here to turn off all global configuration locations, and maintain consistency over configuration/aliases/commandfiles for your team.
