This bundle symfony2 is used to manage payments. You have to use another payment bundle for each payment system. Kitano is just a namespace for bundles created by Kitpages (http://www.kitpages.fr) and Anonymation (http://www.anonymation.com).
This bundle is in a stable state for a simple payment processing.
The following payments systems are supported :
- SIPS (mercanet, elysnet, citelys,...)
You can see a (very) small documentation in french on this page : http://www.kitpages.fr/fr/cms/110/kitanopaymentbundle
