+//| :class:`PewPew` -- LED matrix and button driver
+//| ===============================================
+//|
+//| This is an internal module to be used by the ``pew.py`` library from
+//| https://github.com/pewpew-game/pew-pewpew-standalone-10.x to handle the
+//| LED matrix display and buttons on the ``pewpew10`` board.
+//|
+//| Usage::
+//|
+//|     This singleton class is instantiated by the ``pew`` library, and
+//|     used internally by it. All user-visible interactions are done through
+//|     that library.
+//|
+
+//| .. class:: PewPew(buffer, rows, cols, buttons)
+//|
+//|     Initializes matrix scanning routines.
+//|
+//|     The ``buffer`` is a 64 byte long ``bytearray`` that stores what should
+//|     be displayed on the matrix. ``rows`` and ``cols`` are both lists of
+//|     eight ``DigitalInputOutput`` objects that are connected to the matrix
+//|     rows and columns. ``buttons`` is a ``DigitalInputOutput`` object that
+//|     is connected to the common side of all buttons (the other sides of the
+//|     buttons are connected to rows of the matrix).
