I made a library to access to the Taleo data ( https://github.com/Polzme/Taleo ). I tried to follow the best practice to do it. It's using composer ( http://getcomposer.org/ ) to resolve dependencies to Monolog and Guzzle.
Now, the big question is, how to use my library 'Taleo' in a Drupal module ?
I also tried to include the file 'vendor/autoload.php', but it doesn't works (and it works well in the demo.php file: https://github.com/Polzme/Taleo/blob/master/demo.php)
Before including each file manually, I would like to know if there is a working solution available for Drupal 7.
