Rage is a graphics engine for the Nintendo DS with a C++ interface. It is licensed under the LGPL.

If you’re reading this, then you’re looking at the git repository for main Rage development. If you’re only interested in using Rage to develop NDS applications, or want to learn about Rage, please visit the official Rage site at http://remar.se/andreas/rage instead.

Rage is licensed under the Lesser General Public License. In short, this license allows you to link against Rage without making your source free. If you modify Rage, you must provide the source for the modified Rage version.

The license can be found in the files doc/license/COPYING and doc/license/COPYING.LESSER.

For more on the LGPL, see http://gnu.org/licenses/lgpl.html.

If you’re new to git (the version control system Rage uses) you can find an excellent book at http://progit.org/book. You don’t really have to learn alot of git commands to just fetch the source, but if you want to contribute you should learn a little about how to use git.

Anyway, to fetch the sources once you have git installed, you use this simple command:

git clone git://github.com/remar/rage.git

That should create a ‘rage’ directory in your current dir.

This repository contains everything that’s related to Rage, from the C++ source to the website. Here’s a short rundown of the file structure.

Contains the main Makefile and also the Makefile.bindist that is included when a binary distribution is built.

The files that are used to generate the README files for the binary and source distributions. The README files are generated with m4.

Simple scripts to create the binary and source distributions. Quite straight forward.

The various documentation for Rage.

Contains the Doxyfile that doxygen uses to extract the API documentation from rage.h. (The generated API documentation will be placed in this directory).

The files for the license (LGPL) are located here, COPYING and COPYING.LESSER.

The functional specifications for Rage.

Contains the example projects.

The most important directory! Contains the source for Rage.

The website for Rage. Uses a little php.

The main Makefile has a couple of useful targets that you can use.

The default target, if you don’t provide a target when calling ‘make’, this is what will be built. Creates the directories lib/ and include/ as well, and moves librage.a to lib/ and rage.h to include/.

Clean up everything, including generated documentation.

Moves librage.a to $DEVKITPRO/libnds/lib and rage.h to $DEVKITPRO/libnds/include.

Generates the API documentation with doxygen.

Recursively compiles the examples.

This is mostly a reference for myself when making a release, but you might be interested in the release procedure.

Update the RAGEVERSION variable in bin/version to the new version of Rage.

Update the pages www/index.php, www/downloads.php, and www/tutorial.php so that they contain references to the new release.

Update the NEWS file with information about the new version.

Commit the bump of version and the other updated files.

Create a tag for the new release: git tag -a rage-<VERSION> -m “Release <VERSION> of Rage”

Execute the commands bin/makesrcdist and bin/makebindist. This will create .tar.bz2 and .zip files and place them in ../releases/.

Well, this is an org-mode file. You can learn about org-mode at http://orgmode.org. Basically, it’s an outline mode++ for Emacs. (If you’re reading this at github.com, this section might not make alot of sense.)
