  Key Concepts: 
  An extension point is a feature of the SAP NetWeaver Developer Studio (NWDS) that allows developers to extend the functionality of an existing application. It is a way to add custom code to an existing application without having to modify the original source code. Extension points are defined in the application's manifest file and can be used to add new features, modify existing features, or even replace existing features. 
  
  How to use it: 
  Extension points are defined in the application's manifest file, which is located in the project's root directory. To use an extension point, developers must first create a plug-in project in NWDS. This plug-in project will contain the code that will be used to extend the existing application. Once the plug-in project is created, developers can then add the extension point to the manifest file. The extension point will then be available for use in the application. 
  
  Tips & Tricks: 
  When creating a plug-in project, it is important to ensure that all of the necessary dependencies are included in the project. This includes any libraries or frameworks that are required for the plug-in to function properly. Additionally, it is important to ensure that all of the necessary permissions are granted for the plug-in to access any external resources that it may need.
