+		This is a compiler, simulator, and associated tools for Bluespec High
+		Level Hardware Design Language (HL-HDL), supporting the two optional

+		available in the BSVlang repository.
+		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.

+		两种可选语法：BSV 和 BH。 BSVlang 存储库中提供了语言规范和教程。
+		Bluespec 是一种高级硬件描述语言。它具有各种高级功能，包括强大的类型系统，
+		可以在综合之前防止错误，其最显着的功能是受保护的原子操作，允许您根据硬件
+		组件的不变量以模块化方式定义硬件组件，并让编译器选择一个调度程序。
