- /**
- * All Drush commands are invoked in a specific order, using
- * drush-made hooks, very similar to the Drupal hook system. See drush_invoke()
- * for the actual implementation.
- *
- * For any commandfile named "hook", the following hooks are called, in
- * order, for the command "COMMAND":
- *
- * 0. drush_COMMAND_init()
- * 1. drush_hook_COMMAND_pre_validate()
- * 2. drush_hook_COMMAND_validate()
- * 3. drush_hook_pre_COMMAND()
- * 4. drush_hook_COMMAND()
- * 5. drush_hook_post_COMMAND()
- *
- * For example, here are the hook opportunities for a mysite.drush.inc file
- * that wants to hook into the `pm-download` command.
- *
- * 1. drush_mysite_pm_download_pre_validate()
- * 2. drush_mysite_pm_download_validate()
- * 3. drush_mysite_pre_pm_download()
- * 4. drush_mysite_pm_download()
- * 5. drush_mysite_post_pm_download()
- *
- * Note that the drush_COMMAND_init() hook is only for use by the
- * commandfile that defines the command.
- *
- * If any of hook function fails, either by calling drush_set_error
- * or by returning FALSE as its function result, then the rollback
- * mechanism is called. To fail with an error, call drush_set_error:
- *
- * return drush_set_error('MY_ERROR_CODE', dt('Error message.'));
- *
- * To allow the user to confirm or cancel a command, use drush_confirm
- * and drush_user_abort:
- *
- * if (!drush_confirm(dt('Are you sure?'))) {
- * return drush_user_abort();
- * }
- *
- * The rollback mechanism will call, in reverse, all _rollback hooks.
- * The mysite command file can implement the following rollback hooks:
- *
- * 1. drush_mysite_post_pm_download_rollback()
- * 2. drush_mysite_pm_download_rollback()
- * 3. drush_mysite_pre_pm_download_rollback()
- * 4. drush_mysite_pm_download_validate_rollback()
- * 5. drush_mysite_pm_download_pre_validate_rollback()
- *
- * Before any command is called, hook_drush_init() is also called.
- * hook_drush_exit() is called at the very end of command invocation.
