Mstisse Interfaces Open-Source Program
The Matisse Interfaces Open-Source global initiative launched in Summer 2001 continues to expand and grow. With the support of the Matisse Developer Community, Matisse Software has further formalized its Open-Source program. The adoption of a broad and solid public license was key to give the necessary freedom to both contributors and end-users.
