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