一个 shell 的工具库，用于简化基于命令行应用程序的开发，可方便定义命令以及进入交互模式，可轻松从文件和标准输入中获取数据，提供图形化工作空间，基于 Qt 的界面，如果没有图形界面环境则使用基于 ncurses 的界面- Shellp　is a shell helper library. It is intended to make it easier to write command-line based applications. Commands are easy to define, and can be entered interactively or by reading from a file or standard input. If a graphical workspace is available, a Qt based interface can be used, otherwise an ncurses based one may be available. If the platform doesn t support that either, reading from file is still an option.
