+pyboard interface
+
+This module provides the Pyboard class, used to communicate with and
+control a MicroPython device over a communication channel. Both real
+boards and emulated devices (e.g. running in QEMU) are supported.
+Various communication channels are supported, including a serial
+connection, telnet-style network connection, external process
+connection.
+
+Example usage:
+
+    import pyboard
+    pyb = pyboard.Pyboard('/dev/ttyACM0')
+
+Or:
+
+    pyb = pyboard.Pyboard('192.168.1.1')
+
+Then:
+
+    pyb.enter_raw_repl()
+    pyb.exec('pyb.LED(1).on()')
+    pyb.exit_raw_repl()
+
+Note: if using Python2 then pyb.exec must be written as pyb.exec_.
+To run a script from the local machine on the board and print out the results:
+
+    import pyboard
+    pyboard.execfile('test.py', device='/dev/ttyACM0')
+
+This script can also be run directly.  To execute a local script, use:
+
+    ./pyboard.py test.py
+
+Or:
+
+    python pyboard.py test.py

+"""Toolchain for working with the TiLDA Mk4
+
+Usage (currently more of a wishlist)
+------------------------------------
+
+Reboot badge
+$ tilda_tools reset
+
+Soft reboot badge and start specific app
+$ tilda_tools reset --boot my_app
+
+Update files on the badge to match the current local version, restarts afterwards
+$ tilda_tools sync
+
+Update files in folder(s) to match current local version
+$ tilda_tools sync my_game shared
+$ tilda_tools sync <folder1> <folder2> ...
+
+Sync (as above), but execute my_app after reboot
+$ tilda_toold.py sync --boot my_app [<other sync parameter>]
+
+Sync (as above), but execute a single file afterwards without copying it to the badge
+$ tilda_toold.py sync --run some_other_file.py
+
+Executes a single file on the badge without copying anything (Using pyboard.py)
+$ tilda_tools run my_app/main.py
+
+Runs local validation against metadata (doesn't require a badge)
+$ tilda_tools validate
+
+Runs local validation and badge-side tests
+$ tilda_tools test
+
+Update firmware on badge (warning, this will delete all settings etc. stored on the badge!)
+$ tilda_tools firmware-update
