 synopsis:            A web-based demo for Haskell-tools Refactor.
 description:         Allows websocket clients to connect and performs refactorings on demand. The clients maintain a continous connection with the server, sending changes in the source files. When a refactor request is received, it performs the changes and sends the modified source files to the client.
