+For developers the following non-standard commands might be of interest, mainly useful for debugging:
+
+ * #### bench *ttSize threads limit fenFile limitType evalType*
+ Performs a standard benchmark using various options. The signature of a version
+ (standard node count) is obtained using all defaults. `bench` is currently
+ `bench 16 1 13 default depth mixed`.
+
+ * #### compiler
+ Give information about the compiler and environment used for building a binary.
+
+ * #### d
+ Display the current position, with ascii art and fen.
+
+ * #### eval
+ Return the evaluation of the current position.
+
+ * #### export_net [filename]
+ Exports the currently loaded network to a file.
+ If the currently loaded network is the embedded network and the filename
+ is not specified then the network is saved to the file matching the name
+ of the embedded network, as defined in evaluate.h.
+ If the currently loaded network is not the embedded network (some net set
+ through the UCI setoption) then the filename parameter is required and the
+ network is saved into that file.
+
+ * #### flip
+ Flips the side to move.
