Drush API for downloading module from a script

Question

I am trying to download module using Drush API via drush script as following:

#!/usr/bin/env drush
<?php

// check if we can bootstrap
$self = drush_sitealias_get_record('@self');
if (empty($self)) {
    drush_die("I can't bootstrap from the current location.", 0);
}

// goes to site directory
drush_op('chdir', $self['root']);


drush_include_engine('drupal', 'environment', drush_drupal_major_version());

//****how to download module

drush_module_enable(array('uuid'));

drush_print("Done.");

While i see an Drush API for enabling, i don't see for downloading a module
How to download a module via Drush API from the script? Is there Drush API for automatically detect dependencies, download them and enable? Thank You

If there's an API for this, I think it would be drush_invoke_process. I believe Drush uses that function internally when one command wants to execute another.

The primary function that executes the download work is drush_pm_download(), so you could probably just call it directly as well.

And of course, as a last resort, you could use exec(drush @alias dl $module).
