With the latest build - when you start it from the console gives you an interactive cli shell.
The cli shell's interpreter is the same as the http service api.
For example:

is the same as
/runtime/ls in the shell

it can even be shortened to just ls
because - single command statements are assumed to be runtime methods

but wait there's more !  ... type python

and you have an interactive python console

just made 10 servos with 2 lines of code ;)

can be useful when your ssh into a raspi - all services and methods are accessable.
