# GNU ARM Eclipse

The [GNU ARM Eclipse](http://gnuarmeclipse.github.io) is an open source project that includes a family of Eclipse plug-ins and tools for multi-platform embedded ARM development, based on GNU toolchains. The project is hosted on [GitHub](https://github.com/gnuarmeclipse).

This exporter aims to create managed GNU ARM Eclipse projects, ready to build, and with as many options properly identified and set in the Eclipse C/C++ Build -> Settings page.

## Build plug-in configuration options

All options are prefixed by `ilg.gnuarmeclipse.managedbuild.cross.option.`.
