doxygen

Doxygen是一種開源跨平臺的，以類似JavaDoc風格描述的文檔系統，完全支持C、C++、Java、Objective-C和IDL語言，部分支持PHP、C#。註釋的語法與Qt-Doc、KDoc和JavaDoc兼容。Doxygen可以從一套歸檔源文件開始，生成HTML格式的在線類瀏覽器，或離線的LATEX、RTF參考手冊。

安裝配置環境變量

Graphviz 安裝後需要配置環境變量
將graphviz安裝目錄下的bin文件夾添加到Path環境變量中：

驗證graphviz是否正常

進入windows命令行界面，輸入dot -version，然後按回車，如果顯示graphviz的相關版本信息，則安裝配置成功。
