+========================================================================
+    动态链接库：priread 项目概述
+========================================================================
+
+应用程序向导已为您创建了此 priread DLL。
+
+本文件概要介绍组成 priread 应用程序的每个文件的内容。
+
+
+priread.vcxproj
+    这是使用应用程序向导生成的 VC++ 项目的主项目文件，其中包含生成该文件的 Visual C++ 的版本信息，以及有关使用应用程序向导选择的平台、配置和项目功能的信息。
+
+priread.vcxproj.filters
+    这是使用“应用程序向导”生成的 VC++ 项目筛选器文件。它包含有关项目文件与筛选器之间的关联信息。在 IDE 中，通过这种关联，在特定节点下以分组形式显示具有相似扩展名的文件。例如，“.cpp”文件与“源文件”筛选器关联。
+
+priread.cpp
+    这是主 DLL 源文件。
+
+/////////////////////////////////////////////////////////////////////////////
+其他标准文件:
+
+StdAfx.h, StdAfx.cpp
+    这些文件用于生成名为 priread.pch 的预编译头 (PCH) 文件和名为 StdAfx.obj 的预编译类型文件。
+
+/////////////////////////////////////////////////////////////////////////////
+其他注释:
+
+应用程序向导使用“TODO:”注释来指示应添加或自定义的源代码部分。
