+/**
+ * Show a dialog when the user first opens the keyboard.
+ *
+ * The splash screen is a modal dialog box presented when the user opens this keyboard for the first
+ * time.  It is useful for giving specific warnings that must be shown to the user before use.
+ *
+ * While the splash screen does share with the setup wizard the common goal of presenting
+ * information to the user before use, they are presented at different times and with different
+ * capabilities.  The setup wizard is launched by tapping on the icon, and walks the user through
+ * the setup process.  It can, however, be bypassed by enabling the keyboard from Settings directly.
+ * The splash screen cannot be bypassed, and is therefore more appropriate for obtaining user
+ * consent.
