-================
-This project is the .NET port of POI project. With NPOI, you can read/write Excel and Word files easily. It has a wide application. 
-For example, you can use it a to generate a Excel report without Microsoft Office suite installed on your 
-server and more efficient than call Microsoft Excel ActiveX at background; you can also use it to extract 
-text from Office documents to help you implement full-text indexing feature (most of time this feature is 
-used to create search engines).
