## Concepts

This section of the User Guide provides an overview of the main concepts in Eclipse to create and build programs for Symbian OS.

The Symbian OS plug-ins are a set of Eclipse plug-ins that provide project, SDK and build support for Symbian OS developers. The plug-ins extend the functionality provided by Eclipse and the C/C++ Development Toolkit (CDT).

The plug-ins simplify Symbian OS development by removing the need to use command line build tools, and provide a graphical interface to Symbian OS specific file formats, such as AIF and MBM.

The plug-ins provide a new perspective, called the Carbide.c++ Perspective, on the Eclipse workbench. This perspective enhances the standard CDT C/C++ perspective by allowing you to select easily the SDKs and build target types that you want to use for each project.

The following topics discuss these concepts in more detail:

- SDK Support
- Carbide.c++ Perspective
- AIF File
- MBM File
