/// \code #include "vt100.h" \endcode
/// \par Overview
///             This library provides functions for sending VT100 escape codes to
///     control a connected VT100 or ANSI terminal.  Commonly useful functions
/// include setting the cursor position, clearing the screen, setting the text
/// attributes (bold, inverse, blink, etc), and setting the text color.  This
/// library will slowly be expanded to include support for codes as needed and
/// may eventually receive VT100 escape codes too.
