minimal commentary as smaller source files (Point, Board, Command, Orientation) are self-explanatory (with tests), while larger source files have some comments and rely on larger test suites as explanatory document.

to run (in general)

from OS CLI:

$ mill toyrobot.run <filename>

and similar for testing:

$ mill toyrobot.test
