 Command line options
 ====================
 
 ```
--c      launch the developer console
--m      start mining fake blocks and broadcast fake messages to the net
+-c       Launch the developer console
+-m       Start mining blocks
+-genaddr Generates a new address and private key (destructive action)
+-p       Port on which the server will accept incomming connections (= 30303)
