+class Legion(CMakePackage):
+    """Legion is a data-centric parallel programming system for writing
+       portable high performance programs targeted at distributed heterogeneous
+       architectures. Legion presents abstractions which allow programmers to
+       describe properties of program data (e.g. independence, locality). By
+       making the Legion programming system aware of the structure of program
+       data, it can automate many of the tedious tasks programmers currently
+       face, including correctly extracting task- and data-level parallelism
+       and moving data around complex memory hierarchies. A novel mapping
+       interface provides explicit programmer controlled placement of data in
+       the memory hierarchy and assignment of tasks to processors in a way
+       that is orthogonal to correctness, thereby enabling easy porting and
+       tuning of Legion applications to new architectures.
