Cyborg Configuration Sample

The following is a sample cyborg configuration for adaptation and use. It is auto-generated from cyborg when this documentation is built, so if you are having issues with an option, please compare your version of cyborg with the version of this documentation.

The sample configuration can also be downloaded in file form.
