+Overview - OceanDSL Tools and Analysis
+======================================
+
+The OceanDSL project aims to create DSLs to support the separation of concerns
+in scientific models, including parameter management, configuration, and
+parameter selection. Therefore, we need a good understanding of the code of
+scientific models and therefore, tools to recover architecture and behavior
+of these models.
+
+Thus, we create a growing set of tools to perform architecture recovery or
+discovery when there never was an architecture planned. Analyzes of the
+architecture models and support for optimizing the architecture.
