 The REPL has some special commands, all starting with a dot `.`. They are
 
-- `.help`: shows the dot commands help
-- `.editor`: enables editor mode, to write multiline JavaScript code with ease. Once you are in this mode, enter ctrl-D to run the code you wrote.
-- `.break`: when inputting a multi-line expression, entering the .break command will abort further input. Same as pressing ctrl-C.
-- `.clear`: resets the REPL context to an empty object and clears any multi-line expression currently being input.
-- `.load`: loads a JavaScript file, relative to the current working directory
-- `.save`: saves all you entered in the REPL session to a file (specify the filename)
-- `.exit`: exits the repl (same as pressing ctrl-C two times)
