+%description
+Compiler, simulator, and tools for the Bluespec Hardware Description Language.
+Bluespec is a single language for digital electronic hardware designs that
+comes in two syntactic flavors, which are interchangeable:
+
+    Bluespec SystemVerilog (BSV)
+    Bluespec Haskell (BH, or "Bluespec Classic")
+
+Bluespec is a high-level hardware description language. It has a variety of
+advanced features including a powerful type system that can prevent errors prior
+to synthesis time, and its most distinguishing feature, Guarded Atomic Actions,
+allow you to define hardware components in a modular manner based on their
+invariants, and let the compiler pick a scheduler.
