+ help
+ Say Y here if you want to connect an AltusMetrum ChaosKey to
+ your computer's USB port. The ChaosKey is a hardware random
+ number generator which hooks into the kernel entropy pool to
+ ensure a large supply of entropy for /dev/random and
+ /dev/urandom and also provides direct access via /dev/chaoskeyX
+
+ To compile this driver as a module, choose M here: the
+ module will be called chaoskey.
