Drush\Preflight
Classes
Preprocess commandline arguments.
Map commandline arguments from one value to another during preflight.
Prepare to bootstrap Drupal
The Drush preflight determines what needs to be done for this request.
Storage for arguments preprocessed during preflight.
Helper methods to verify preflight state.
RedispatchToSiteLocal forces an exec
to the site-local Drush if it
exist. We must do this super-early, before loading Drupal's autoload
file. If we do not, we will crash unless the site-local Drush and the
global Drush are using the exact same versions of all dependencies, which
will rarely line up sufficiently to prevent problems.
