From the developer:
e² studio is a complete development and debug environment based on the popular Eclipse CDT project. Essentially open source, the Eclipse CDT covers the build (editor, compiler, and linker control) as well as the debugging phase based on an extended GDB interface. e² studio will automatically scan the generated linker map file to prepare the Memory Usage view.
