This is a bare Git repository. Probably if you are reading this it is because you have instead opened it in a browser. If you want to access its contents, the most practical way to do so is with this command:
git clone http://canonical.org/~kragen/sw/OpenRadioss.git
This is a clone of https://github.com/AxelHaenschke/OpenRadioss as of 02026-10-01, because it seems like Siemens is pulling some kind of dirty trick to take GitHub clones of their AGPL-licensed OpenRadioss codebase offline.
