Code::Blocks is a cross-platform Integrated Development Environment
(IDE). It is based on a self-developed plugin framework allowing
unlimited extensibility. Most of its functionality is already provided
by plugins. Plugins included in the base package are:

• Compiler frontend to many free compilers


• Debugger frontend for GDB (and CDB for windows platforms)


• Source formatter (based on AStyle)


• Wizard to create new C++ classes


• Code-completion / symbols-browser (work in progress)


• Default MIME handler


• Wizard to create new Code::Blocks plugins


• To-do list


• Extensible wizard based on scripts


• Autosave (saves your work in the unfortunate case of a crash)¹
