Modifying dopamine to accept continuous action spaces

Could you possibly comment on the difficult of getting dopamine to work with continuous action spaces? Is this something that could be done with a bit of effort, or are the agents completely incompatible with this type of action space? I wanted to have a go getting dopamine to work with the OpenAI Gym BipedalWalker environment. I managed to get all of the initialization and setup working, then realized an assumption of discreet action spaces was hard-coded into dopamine.
