These are the official behaviors of Mandango.
Hint
You can install them directly, from git, svn.
There is an access through Subversion to the Git repository.
To use these behaviors you just have to add their namespace to the class loader:
use Symfony\Component\ClassLoader\UniversalClassLoader;
$loader = new UniversalClassLoader();
$loader->registerNamespaces(array(
'Mandango\Behavior' => '/path/to/mandango-behaviors/src',
'Mandango' => '/path/to/mandango/src',
));
$loader->register();
