 * `deepclrun` becomes `deepcl_train`: handles training, and validation, using labelled data
 * `deepclexec` becomes `deepcl_predict`: handles creating predictions from unlabelled data
+* lua wrappers removed.  Effort for lua has moved to [cltorch](https://github.com/hughperkins/cltorch) and [clnn](https://github.com/hughperkins/clnn), both of which are well underway :-)
 * `deepcl_predict` can take input from a file, using GenericLoader, same formats as training, or from stdin
 * `deepcl_predict` can output to a file, or to stdout, in text or binary format
