+"""The EC console interpreter.
+
+EC-3PO is a console interpreter which migrates the rich debug console from the
+EC itself to the host.  This allows for a rich debug console without impacting
+EC image sizes while also allowing the development of new console features.
+
+The package consists of two modules: console and interpreter.  The console
+module provides the interactive console interface between the user and the
+interpreter.  It handles the presentation of the EC console including editing
+methods as well as session-persistent command history.
+
+The interpreter module provides the interpretation layer between the EC UART and
+the user.  The user does not necessarily have to be the interactive console, but
+could be something like autotest.  The interpreter is also responsible for the
+automatic command retrying if the EC drops a character in a command.  This is a
+stopgap until all commands are communicated via host commands.
