Drupal modules

Calendar 

Views plugin to display views containing dates as Calendars. Adds "Calendar" format and provides "Calendar Entity".

Enabled by default.
It's used by: "Calendar absence list" Drupal View

Loading Civicrm js and css files in drupal.

As following the example from README.txt:
- civicrm_resources_load('org.civicrm.hrjobcontract', array('gulpfile.js', 'contact.js', '*.css'));
This will load all css files and 2 js files listed in array located anywhere in extension "Job Contract (CiviHR)".

Currently we do such things differently:
$jsOptions = array('type' => 'file', 'scope' => 'footer');
drupal_add_js(CRM_Core_Resources::singleton()->getUrl('org.civicrm.hrjobcontract') . "js/gulpfile.js", $jsOptions);
for adding scripts to Drupal pages.

Enabled by default.
It's used in Angular SSP apps to load resources/assets from CiviCRM extensions

Build site based on required settings.
Provides a /site_builder/build page which starts to build a buildkit site in the background by executing php code with pretty much hardcoded patchs and file names:

$cmd = 'sh ' . $buildkit_url . '/site-builder.sh test-2015';
$outputfile = $buildkit_url . '/site-builder-out-2015.log';
$pidfile = $buildkit_url . '/site-builder-pids-2015.log';

// This will start a background process and will build the site
// It will populate the .log file / each build so we can check the progress of the build
// It will also append the pids file to track what pids the process is using
exec(sprintf("%s > %s 2>&1 & echo $! >> %s", $cmd, $outputfile, $pidfile));
