+ * This is a tiny implementation of the (n)curses library intended to be
+ * used in embedded/firmware/BIOS code where no libc or operating system
+ * environment is available and code size is very important.
+ *
+ * Design goals:
+ * - Small object code.
+ * - Self-contained.
+ * - Doesn't require a libc (no glibc/uclibc/dietlibc/klibc/newlib).
+ * - Works without any other external libraries or header files.
+ * - Works without an underlying operating system.
+ * - Doesn't use files, signals, syscalls, ttys, library calls, etc.
+ * - Doesn't do any dynamic memory allocation (no malloc() and friends).
+ * - All data structures are statically allocated.
+ * - Supports standard VGA console (80x25) and serial port console.
+ * - This includes character output and keyboard input over serial.
+ * - Supports beep() through a minimal PC speaker driver.
+ *
+ * Limitations:
+ * - Only implements a small subset of the (n)curses functions.
+ * - Only implements very few sanity checks (for smaller code).
+ * - Thus: Don't do obviously stupid things in your code.
+ * - Doesn't implement the 'form', 'panel', and 'menu' extentions.
+ * - Only implements C bindings (no C++, Ada95, or others).
+ * - Doesn't include wide character support.
