After a long hiatus, the project is now restarting in other repositories in a GitHub organization: https://github.com/symphony-mp. The project will be open-source, multi-platform and will include both online and offline resources.
Soon this old repository will be private or deleted so if you are interested, a contributor or want to contribute to the project I suggest you migrate to the new repositories available here: https://github.com/symphony-mp.
Sincerely, João Sereia<[email protected]>.
