PySy 是一个基于 JR 编程语言的 Python 包，当前支持 Python 2.x。
PySy implements many of the JR features in the form of a Python package. The end goal of PySy is to provide its users a useful and expressive environment for implementing concurrent and distributed programs. PySy provides abstractions for expressing several concurrent programming mechanisms, e.g., rendezvous, dynamic process creation, remote method invocation (RMI), and asynchronous message passing, which are easy to use and require significantly less user code than other existing Python concurrent and distributed programming alternatives.
