+### Status
+
+Things may work for you, or may not.  Things may never work because of huge differences between Linux and Windows.  Or things may work in future, if you report the problem on [GitHub](https://github.com/rmyorston/busybox-w32) or [GitLab](https://gitlab.com/rmyorston/busybox-w32).  If you don't have an account on one of those or you'd prefer to communicate privately you can email [rmy@pobox.com](mailto:rmy@pobox.com).
+
+Additional information is available from the [BusyBox for Windows](https://frippery.org/busybox/index.html) web page.  In particular:
+
+- There are [downloads](https://frippery.org/busybox/index.html#downloads) of precompiled binaries for i686, x86_64 and aarch64.
+- Release notes for the [current](https://frippery.org/busybox/release-notes/current.html) and [previous](https://frippery.org/busybox/release-notes/index.html) releases are available.
+
+### Building
+
+You need a MinGW toolchain and a POSIX environment.  I cross-compile on Linux.  On Fedora the following should pull in everything required:
+
+`dnf install gcc make ncurses-devel perl-Pod-Html`
+
+`dnf install mingw64-gcc` (for a 64-bit build)
+
+`dnf install mingw32-gcc` (for a 32-bit build)
+
+On Microsoft Windows you can install [w64devkit](https://github.com/skeeto/w64devkit/releases).  Get the `-i686` variant for a 32-bit build.  Unzip the file and run `w64devkit/w64devkit.exe`.
+
+On either Linux or Windows the commands `make mingw64_defconfig` or `make mingw32_defconfig` will pick up the default configuration.  You can then customize your build with `make menuconfig` or by editing `.config`, if you know what you're doing.
+
+Then just `make`.
+
+See the [Building busybox-w32](https://frippery.org/busybox/build.html) web page for additional information.
+
+### Hints
+
+ - Use forward slashes in paths:  Windows doesn't mind and the shell will be happier.
+ - Windows paths are different from Unix ([more detail](https://frippery.org/busybox/paths.html)):
+   * Absolute paths: `c:/path` or `//host/share/path`
+   * Relative to current directory of other drive: `c:path`
+   * Relative to current root (drive or share): `/path`
+   * Relative to current directory of current root (drive or share): `path`
+ - Handling of users, groups and permissions is totally bogus.  The system only admits to knowing about the current user and employs various heuristics to synthesise uid, gid and permission values.
+ - Some crufty old Windows code (Windows XP, cmd.exe) doesn't like forward slashes in environment variables.  The -X shell option prevents busybox-w32 from changing backslashes to forward slashes.  If Windows programs don't run from the shell it's worth trying it.
+ - If you want to install 32-bit BusyBox in a system directory on a 64-bit version of Windows you should put it in `C:\Windows\SysWOW64`, not `C:\Windows\System32` as you might expect.  On 64-bit systems the latter is for 64-bit binaries.
+ - The system tries to detect the best way to handle the terminal being used.  If this doesn't work you can try setting the environment variable `BB_TERMINAL_MODE=1` to force the use of literal ANSI escapes or `BB_TERMINAL_MODE=0` to emulate them using the Windows console API.
+ - busybox-w32 prefers built-in applets to external programs when running commands. This preference can be overridden by setting the environment variable `BB_OVERRIDE_APPLETS` to a space-separated list of applet names. Thus, to use an external `make` in preference to the built-in applet set `BB_OVERRIDE_APPLETS="make"`.
+ - It's possible to obtain pseudo-random numbers using `if=/dev/urandom` as the input file to `dd`.  The same emulation of `/dev/urandom` is used internally by the `shred` utility and to support https in `wget`.  Serious users of random numbers may, of course, wish to make alternative arrangements.

+These scripts can be used to cross-compile busybox-w32 on a
+Fedora Linux system with mingw-w64 and llvm-mingw toolchains.
+The former are available from the Fedora repositories; the
+latter needs to be downloaded and installed from:
+
+   https://github.com/mstorsjo/llvm-mingw
+
+The script should be run from the directory above a git repository
+named busybox-w32.  The builds are performed in the directories
+named in the TARGETS variable in the scripts.  Previous copies of
+these directories are deleted.
+
+The scripts check out the master branch of the git repository.  You
+should edit the script if you wish to build from a different commit.
+
+The build time recorded in the executables is the time of the checked
+out commit.  This may not result in a perfectly reproducible build
+but it's a step in that direction.
+
+The release build performs some additional optimisation and takes
+slightly longer as a result.
+
+The busybox-w32 help message includes information about the build
+platform.  Obtaining this information is very specific to the
+platform used:  you may need to adjust this if building on something
+other than Fedora.

+PDCurses for Windows console
+============================
+
+This directory contains PDCurses source code files specific to the
+Microsoft Windows console. Although historically called "Win32", this
+port can just as easily be built for 64-bit systems. Windows 95 through
+Windows 10 are covered. (Some features require later versions.)
+
+
+Acknowledgements

+
+Windows console port was originally provided by Chris Szurgot
+<szurgot@itribe.net>
+
+
+Distribution Status
+-------------------
+
+The files in this directory are released to the public domain.

+
+### Description
+
+   addch() adds the chtype ch to the default window (stdscr) at the
+   current cursor position, and advances the cursor. Note that chtypes
+   can convey both text (a single character) and attributes, including a
+   color pair. add_wch() is the wide-character version of this function,
+   taking a pointer to a cchar_t instead of a chtype.
+
+   waddch() is like addch(), but also lets you specify the window. (This
+   is in fact the core output routine.) wadd_wch() is the wide version.
+
+   mvaddch() moves the cursor to the specified (y, x) position, and adds
+   ch to stdscr. mvadd_wch() is the wide version.
+
+   mvwaddch() moves the cursor to the specified position and adds ch to
+   the specified window. mvwadd_wch() is the wide version.
+
+   echochar() adds ch to stdscr at the current cursor position and calls
+   refresh(). echo_wchar() is the wide version.
+
+   wechochar() adds ch to the specified window and calls wrefresh().
+   wecho_wchar() is the wide version.
+
+   addrawch(), waddrawch(), mvaddrawch() and mvwaddrawch() are PDCurses-
+   specific wrappers for addch() etc. that disable the translation of
+   control characters.
+
+   The following applies to all these functions:
+
+   If the cursor moves on to the right margin, an automatic newline is
+   performed. If scrollok is enabled, and a character is added to the
+   bottom right corner of the window, the scrolling region will be
+   scrolled up one line. If scrolling is not allowed, ERR will be
+   returned.
+
+   If ch is a tab, newline, or backspace, the cursor will be moved
+   appropriately within the window. If ch is a newline, the clrtoeol
+   routine is called before the cursor is moved to the beginning of the
+   next line. If newline mapping is off, the cursor will be moved to
+   the next line, but the x coordinate will be unchanged. If ch is a
+   tab the cursor is moved to the next tab position within the window.
+   If ch is another control character, it will be drawn in the ^X
+   notation. Calling the inch() routine after adding a control
+   character returns the representation of the control character, not
+   the control character.
+
+   Video attributes can be combined with a character by ORing them into
+   the parameter. Text, including attributes, can be copied from one
+   place to another by using inch() and addch().
+
+   Note that in PDCurses, for now, a cchar_t and a chtype are the same.
+   The text field is 16 bits wide, and is treated as Unicode (UCS-2)
+   when PDCurses is built with wide-character support (define PDC_WIDE).
+   So, in functions that take a chtype, like addch(), both the wide and
+   narrow versions will handle Unicode. But for portability, you should
+   use the wide functions.
+
+### Return Value
+
+   All functions return OK on success and ERR on error.

+
+### Description
+
+   These routines write all the characters of the null-terminated string
+   str or wide-character string wstr to the given window. The
+   functionality is similar to calling waddch() once for each character
+   in the string; except that, when PDCurses is built with wide-
+   character support enabled, the narrow-character functions treat the
+   string as a multibyte string in the current locale, and convert it.
+   The routines with n as the last argument write at most n characters;
+   if n is negative, then the entire string will be added.
+
+### Return Value
+
+   All functions return OK or ERR.

+
+### Description
+
+   These functions manipulate the current attributes and/or colors of
+   the named window. These attributes can be any combination of
+   A_STANDOUT, A_REVERSE, A_BOLD, A_DIM, A_BLINK, A_UNDERLINE. These
+   constants are defined in "curses.h" and can be combined with the
+   bitwise-OR operator (|).
+
+   The current attributes of a window are applied to all chtypes that
+   are written into the window with waddch(). Attributes are a property
+   of the chtype, and move with the character through any scrolling or
+   insert/delete operations.
+
+   wattrset() sets the current attributes of the given window to attrs.
+   attrset() is the stdscr version.
+
+   wattroff() turns off the named attributes without affecting any other
+   attributes; wattron() turns them on.
+
+   wcolor_set() sets the window color to the value of color_pair. opts
+   is unused.
+
+   standout() is the same as attron(A_STANDOUT). standend() is the same
+   as attrset(A_NORMAL); that is, it turns off all attributes.
+
+   The attr_* and wattr_* functions are intended for use with the WA_*
+   attributes. In PDCurses, these are the same as A_*, and there is no
+   difference in bevahior from the chtype-based functions. In all cases,
+   opts is unused.
+
+   wattr_get() retrieves the attributes and color pair for the specified
+   window.
+
+   wchgat() sets the color pair and attributes for the next n cells on
+   the current line of a given window, without changing the existing
+   text, or alterting the window's attributes. An n of -1 extends the
+   change to the edge of the window. The changes take effect
+   immediately. opts is unused.
+
+   wunderscore() turns on the A_UNDERLINE attribute; wunderend() turns
+   it off. underscore() and underend() are the stdscr versions.
+
+### Return Value
+
+   All functions return OK on success and ERR on error.

+    void wbkgrndset(WINDOW *win, const cchar_t *wch);
+    int wgetbkgrnd(WINDOW *win, cchar_t *wch);
+
+### Description
+
+   bkgdset() and wbkgdset() manipulate the background of a window. The
+   background is a chtype consisting of any combination of attributes
+   and a character; it is combined with each chtype added or inserted to
+   the window by waddch() or winsch(). Only the attribute part is used
+   to set the background of non-blank characters, while both character
+   and attributes are used for blank positions.
+
+   bkgd() and wbkgd() not only change the background, but apply it
+   immediately to every cell in the window.
+
+   wbkgrnd(), wbkgrndset() and wgetbkgrnd() are the "wide-character"
+   versions of these functions, taking a pointer to a cchar_t instead of
+   a chtype. However, in PDCurses, cchar_t and chtype are the same.
+
+   The attributes that are defined with the attrset()/attron() set of
+   functions take precedence over the background attributes if there is
+   a conflict (e.g., different color pairs).
+
+### Return Value
+
+   bkgd() and wbkgd() return OK, unless the window is NULL, in which
+   case they return ERR.
+
+### Portability

+### Description
+
+   border(), wborder(), and box() draw a border around the edge of the
+   window. If any argument is zero, an appropriate default is used:
+
+    ls    left side of border             ACS_VLINE
+    rs    right side of border            ACS_VLINE
+    ts    top side of border              ACS_HLINE
+    bs    bottom side of border           ACS_HLINE
+    tl    top left corner of border       ACS_ULCORNER
+    tr    top right corner of border      ACS_URCORNER
+    bl    bottom left corner of border    ACS_LLCORNER
+    br    bottom right corner of border   ACS_LRCORNER
+
+   hline() and whline() draw a horizontal line, using ch, starting from
+   the current cursor position. The cursor position does not change. The
+   line is at most n characters long, or as many as will fit in the
+   window.
+
+   vline() and wvline() draw a vertical line, using ch, starting from
+   the current cursor position. The cursor position does not change. The
+   line is at most n characters long, or as many as will fit in the
+   window.
+
+   The *_set functions are the "wide-character" versions, taking
+   pointers to cchar_t instead of chtype. Note that in PDCurses, chtype
+   and cchar_t are the same.
+
+### Return Value

+
+   clrtobot() and wclrtobot() clear the window from the current cursor
+   position to the end of the window.
+
+   clrtoeol() and wclrtoeol() clear the window from the current cursor

+
+    int PDC_set_line_color(short color);
+
+### Description
+
+   To use these routines, first, call start_color(). Colors are always
+   used in pairs, referred to as color-pairs. A color-pair is created by
+   init_pair(), and consists of a foreground color and a background
+   color. After initialization, COLOR_PAIR(n) can be used like any other
+   video attribute.
+
+   has_colors() reports whether the terminal supports color.
+
+   start_color() initializes eight basic colors (black, red, green,
+   yellow, blue, magenta, cyan, and white), and two global variables:
+   COLORS and COLOR_PAIRS (respectively defining the maximum number of
+   colors and color-pairs the terminal is capable of displaying).
+
+   init_pair() changes the definition of a color-pair. It takes three
+   arguments: the number of the color-pair to be redefined, and the new
+   values of the foreground and background colors. The pair number must
+   be between 0 and COLOR_PAIRS - 1, inclusive. The foreground and
+   background must be between 0 and COLORS - 1, inclusive. If the color
+   pair was previously initialized, the screen is refreshed, and all
+   occurrences of that color-pair are changed to the new definition.
+
+   pair_content() is used to determine what the colors of a given color-
+   pair consist of.
+
+   can_change_color() indicates if the terminal has the capability to
+   change the definition of its colors.
+
+   init_color() is used to redefine a color, if possible. Each of the
+   components -- red, green, and blue -- is specified in a range from 0
+   to 1000, inclusive.
+
+   color_content() reports the current definition of a color in the same
+   format as used by init_color().
+
+   assume_default_colors() and use_default_colors() emulate the ncurses
+   extensions of the same names. assume_default_colors(f, b) is
+   essentially the same as init_pair(0, f, b) (which isn't allowed); it
+   redefines the default colors. use_default_colors() allows the use of
+   -1 as a foreground or background color with init_pair(), and calls
+   assume_default_colors(-1, -1); -1 represents the foreground or
+   background color that the terminal had at startup. If the environment
+   variable PDC_ORIGINAL_COLORS is set at the time start_color() is
+   called, that's equivalent to calling use_default_colors().
+
+   alloc_pair(), find_pair() and free_pair() are also from ncurses.
+   free_pair() marks a pair as unused; find_pair() returns an existing
+   pair with the specified foreground and background colors, if one
+   exists. And alloc_pair() returns such a pair whether or not it was
+   previously set, overwriting the oldest initialized pair if there are
+   no free pairs.
+
+   PDC_set_line_color() is used to set the color, globally, for the
+   color of the lines drawn for the attributes: A_UNDERLINE, A_LEFT and
+   A_RIGHT. A value of -1 (the default) indicates that the current
+   foreground color should be used.
+
+   NOTE: COLOR_PAIR() and PAIR_NUMBER() are implemented as macros.
+
+### Return Value
+
+   Most functions return OK on success and ERR on error. has_colors()
+   and can_change_colors() return TRUE or FALSE. alloc_pair() and
+   find_pair() return a pair number, or -1 on error.

+
+### Description
+
+   With the getch(), wgetch(), mvgetch(), and mvwgetch() functions, a
+   character is read from the terminal associated with the window. In
+   nodelay mode, if there is no input waiting, the value ERR is
+   returned. In delay mode, the program will hang until the system
+   passes text through to the program. Depending on the setting of
+   cbreak(), this will be after one character or after the first
+   newline. Unless noecho() has been set, the character will also be
+   echoed into the designated window.
+
+   If keypad() is TRUE, and a function key is pressed, the token for
+   that function key will be returned instead of the raw characters.
+   Possible function keys are defined in "curses.h" with integers
+   beginning with 0401, whose names begin with KEY_.
+
+   If nodelay(win, TRUE) has been called on the window and no input is
+   waiting, the value ERR is returned.
+
+   ungetch() places ch back onto the input queue to be returned by the
+   next call to wgetch().
+
+   flushinp() throws away any type-ahead that has been typed by the user
+   and has not yet been read by the program.
+
+   wget_wch() is the wide-character version of wgetch(), available when
+   PDCurses is built with the PDC_WIDE option. It takes a pointer to a
+   wint_t rather than returning the key as an int, and instead returns
+   KEY_CODE_YES if the key is a function key. Otherwise, it returns OK
+   or ERR. It's important to check for KEY_CODE_YES, since regular wide
+   characters can have the same values as function key codes.
+
+   unget_wch() puts a wide character on the input queue.
+
+   PDC_get_key_modifiers() returns the keyboard modifiers (shift,
+   control, alt, numlock) effective at the time of the last getch()
+   call. Use the macros PDC_KEY_MODIFIER_* to determine which
+   modifier(s) were set. PDC_return_key_modifiers() tells getch() to
+   return modifier keys pressed alone as keystrokes (KEY_ALT_L, etc.).
+   These may not work on all platforms.
+
+   NOTE: getch() and ungetch() are implemented as macros, to avoid
+   conflict with many DOS compiler's runtime libraries.

+
+    void getyx(WINDOW *win, int y, int x);
+    void getparyx(WINDOW *win, int y, int x);
+    void getbegyx(WINDOW *win, int y, int x);
+    void getmaxyx(WINDOW *win, int y, int x);
+
+    void getsyx(int y, int x);
+    void setsyx(int y, int x);
+
+    int getbegy(WINDOW *win);
+    int getbegx(WINDOW *win);
+    int getcury(WINDOW *win);
+    int getcurx(WINDOW *win);
+    int getpary(WINDOW *win);
+    int getparx(WINDOW *win);
+    int getmaxy(WINDOW *win);
+    int getmaxx(WINDOW *win);
+
+### Description
+
+   The getyx() macro (defined in curses.h -- the prototypes here are
+   merely illustrative) puts the current cursor position of the
+   specified window into y and x. getbegyx() and getmaxyx() return the
+   starting coordinates and size of the specified window, respectively.
+   getparyx() returns the starting coordinates of the parent's window,
+   if the specified window is a subwindow; otherwise it sets y and x to
+   -1. These are all macros.
+
+   getsyx() gets the coordinates of the virtual screen cursor, and
+   stores them in y and x. If leaveok() is TRUE, it returns -1, -1. If
+   lines have been removed with ripoffline(), then getsyx() includes
+   these lines in its count; so, the returned y and x values should only
+   be used with setsyx().
+
+   setsyx() sets the virtual screen cursor to the y, x coordinates. If
+   either y or x is -1, leaveok() is set TRUE, else it's set FALSE.
+
+   getsyx() and setsyx() are meant to be used by a library routine that
+   manipulates curses windows without altering the position of the
+   cursor. Note that getsyx() is defined only as a macro.
+
+   getbegy(), getbegx(), getcurx(), getcury(), getmaxy(), getmaxx(),
+   getpary(), and getparx() return the appropriate coordinate or size
+   values, or ERR in the case of a NULL window.

+
+### Description
+
+   The inch() functions retrieve the character and attribute from the
+   current or specified window position, in the form of a chtype. If a
+   NULL window is specified, (chtype)ERR is returned.
+
+   The in_wch() functions are the wide-character versions; instead of
+   returning a chtype, they store a cchar_t at the address specified by
+   wcval, and return OK or ERR. (No value is stored when ERR is
+   returned.) Note that in PDCurses, chtype and cchar_t are the same.

+
+### Description
+
+   initscr() should be the first curses routine called. It will
+   initialize all curses data structures, and arrange that the first
+   call to refresh() will clear the screen. In case of error, initscr()
+   will write a message to standard error and end the program.
+
+   endwin() should be called before exiting or escaping from curses mode
+   temporarily. It will restore tty modes, move the cursor to the lower
+   left corner of the screen and reset the terminal into the proper
+   non-visual mode. To resume curses after a temporary escape, call
+   refresh() or doupdate().
+
+   isendwin() returns TRUE if endwin() has been called without a
+   subsequent refresh, unless SP is NULL.
+
+   In some implementations of curses, newterm() allows the use of
+   multiple terminals. Here, it's just an alternative interface for
+   initscr(). It always returns SP, or NULL.
+
+   delscreen() frees the memory allocated by newterm() or initscr(),
+   since it's not freed by endwin(). This function is usually not
+   needed. In PDCurses, the parameter must be the value of SP, and
+   delscreen() sets SP to NULL.
+
+   set_term() does nothing meaningful in PDCurses, but is included for
+   compatibility with other curses implementations.
+
+   resize_term() is effectively two functions: When called with nonzero
+   values for nlines and ncols, it attempts to resize the screen to the
+   given size. When called with (0, 0), it merely adjusts the internal
+   structures to match the current size after the screen is resized by
+   the user. On the currently supported platforms, SDL, Windows console,
+   and X11 allow user resizing, while DOS, OS/2, SDL and Windows console
+   allow programmatic resizing. If you want to support user resizing,
+   you should check for getch() returning KEY_RESIZE, and/or call
+   is_termresized() at appropriate times; if either condition occurs,
+   call resize_term(0, 0). Then, with either user or programmatic
+   resizing, you'll have to resize any windows you've created, as
+   appropriate; resize_term() only handles stdscr and curscr.
+
+   is_termresized() returns TRUE if the curses screen has been resized
+   by the user, and a call to resize_term() is needed. Checking for
+   KEY_RESIZE is generally preferable, unless you're not handling the
+   keyboard.
+
+   curses_version() returns a string describing the version of PDCurses.
+
+   PDC_get_version() fills a PDC_VERSION structure provided by the user
+   with more detailed version info (see curses.h).
+
+   set_tabsize() sets the tab interval, stored in TABSIZE.
+
+### Return Value
+
+   All functions return NULL on error, except endwin(), which always
+   returns OK, and resize_term(), which returns either OK or ERR.

+
+### Description
+
+   cbreak() and nocbreak() toggle cbreak mode. In cbreak mode,
+   characters typed by the user are made available immediately, and
+   erase/kill character processing is not performed. In nocbreak mode,
+   typed characters are buffered until a newline or carriage return.
+   Interrupt and flow control characters are unaffected by this mode.
+   PDCurses always starts in cbreak mode.
+
+   echo() and noecho() control whether typed characters are echoed by
+   the input routine. Initially, input characters are echoed. Subsequent
+   calls to echo() and noecho() do not flush type-ahead.
+
+   halfdelay() is similar to cbreak(), but allows for a time limit to be
+   specified, in tenths of a second. This causes getch() to block for
+   that period before returning ERR if no key has been received. tenths
+   must be between 1 and 255.
+
+   keypad() controls whether getch() returns function/special keys as
+   single key codes (e.g., the left arrow key as KEY_LEFT). Per X/Open,
+   the default for keypad mode is OFF. You'll probably want it on. With
+   keypad mode off, if a special key is pressed, getch() does nothing or
+   returns ERR.
+
+   nodelay() controls whether wgetch() is a non-blocking call. If the
+   option is enabled, and no input is ready, wgetch() will return ERR.
+   If disabled, wgetch() will hang until input is ready.
+
+   nl() enables the translation of a carriage return into a newline on
+   input. nonl() disables this. Initially, the translation does occur.
+
+   raw() and noraw() toggle raw mode. Raw mode is similar to cbreak
+   mode, in that characters typed are immediately passed through to the
+   user program. The difference is that in raw mode, the INTR, QUIT,
+   SUSP, and STOP characters are passed through without being
+   interpreted, and without generating a signal.
+
+   In PDCurses, the meta() function sets raw mode on or off.
+
+   timeout() and wtimeout() set blocking or non-blocking reads for the
+   specified window. If the delay is negative, a blocking read is used;
+   if zero, then non-blocking reads are done -- if no input is waiting,
+   ERR is returned immediately. If the delay is positive, the read
+   blocks for the delay period; if the period expires, ERR is returned.
+   The delay is given in milliseconds, but this is rounded down to 50ms
+   (1/20th sec) intervals, with a minimum of one interval if a postive
+   delay is given; i.e., 1-99 will wait 50ms, 100-149 will wait 100ms,
+   etc.
+
+   wgetdelay() returns the delay timeout as set in wtimeout().
+
+   intrflush(), notimeout(), noqiflush(), qiflush() and typeahead() do
+   nothing in PDCurses, but are included for compatibility with other
+   curses implementations.
+
+   crmode() and nocrmode() are archaic equivalents to cbreak() and
+   nocbreak(), respectively.
+
+   is_keypad() reports whether the specified window is in keypad mode.
+
+   is_nodelay() reports whether the specified window is in nodelay mode.
+
+### Return Value
+
+   is_keypad() and is_nodelay() return TRUE or FALSE. is_notimeout() is
+   provided for compatibility with other curses implementations, and
+   always returns FALSE. All others return OK on success and ERR on error.

+
+### Description
+
+   def_prog_mode() and def_shell_mode() save the current terminal modes
+   as the "program" (in curses) or "shell" (not in curses) state for use
+   by the reset_prog_mode() and reset_shell_mode() functions. This is
+   done automatically by initscr().
+
+   reset_prog_mode() and reset_shell_mode() restore the terminal to
+   "program" (in curses) or "shell" (not in curses) state. These are
+   done automatically by endwin() and doupdate() after an endwin(), so
+   they would normally not be called before these functions.
+
+   savetty() and resetty() save and restore the state of the terminal
+   modes. savetty() saves the current state in a buffer, and resetty()
+   restores the state to what it was at the last call to savetty().
+
+   curs_set() alters the appearance of the cursor. A visibility of 0
+   makes it disappear; 1 makes it appear "normal" (usually an underline)
+   and 2 makes it "highly visible" (usually a block).
+
+   ripoffline() reduces the size of stdscr by one line. If the "line"
+   parameter is positive, the line is removed from the top of the
+   screen; if negative, from the bottom. Up to 5 lines can be ripped off
+   stdscr by calling ripoffline() repeatedly. The function argument,
+   init, is called from within initscr() or newterm(), so ripoffline()
+   must be called before either of these functions. The init function
+   receives a pointer to a one-line WINDOW, and the width of the window.
+   Calling ripoffline() with a NULL init function pointer is an error.
+
+   napms() suspends the program for the specified number of
+   milliseconds. draino() is an archaic equivalent. Note that since
+   napms() attempts to give up a time slice and yield control back to
+   the OS, all times are approximate. (In DOS, the delay is actually
+   rounded down to 50ms (1/20th sec) intervals, with a minimum of one
+   interval; i.e., 1-99 will wait 50ms, 100-149 will wait 100ms, etc.)
+   0 returns immediately.
+
+   resetterm(), fixterm() and saveterm() are archaic equivalents for
+   reset_shell_mode(), reset_prog_mode() and def_prog_mode(),
+   respectively.
+
+### Return Value
+
+   All functions return OK on success and ERR on error, except
+   curs_set(), which returns the previous visibility.

+
+    int move(int y, int x);

+    int wmove(WINDOW *win, int y, int x);
+
+### Description
+
+   move() and wmove() move the cursor associated with the window to the

+    bool is_leaveok(const WINDOW *win);
+    bool is_scrollok(const WINDOW *win);
+
+### Description
+
+   With clearok(), if bf is TRUE, the next call to wrefresh() with this
+   window will clear the screen completely and redraw the entire screen.
+
+   immedok(), called with a second argument of TRUE, causes an automatic
+   wrefresh() every time a change is made to the specified window.
+
+   Normally, the hardware cursor is left at the location of the window
+   being refreshed. leaveok() allows the cursor to be left wherever the
+   update happens to leave it. It's useful for applications where the
+   cursor is not used, since it reduces the need for cursor motions. If
+   possible, the cursor is made invisible when this option is enabled.
+
+   wsetscrreg() sets a scrolling region in a window; "top" and "bot" are
+   the line numbers for the top and bottom margins. If this option and
+   scrollok() are enabled, any attempt to move off the bottom margin
+   will cause all lines in the scrolling region to scroll up one line.
+   setscrreg() is the stdscr version.
+
+   wgetscrreg() gets the top and bottom margins as set in wsetscrreg().
+
+   idlok() and idcok() do nothing in PDCurses, but are provided for
+   compatibility with other curses implementations, likewise is_idlok()
+   and is_idcok().
+
+   raw_output() enables the output of raw characters using the standard
+   *add* and *ins* curses functions (that is, it disables translation of
+   control characters).
+
+   is_cleared() reports whether the specified window causes clear at next
+   refresh.
+
+   is_immedok() reports whether the specified window is in immedok mode.
+
+   is_leaveok() reports whether the specified window is in leaveok mode.
+
+   is_scrollok() reports whether the specified window allows scrolling.
+
+### Return Value
+
+   is_cleared(), is_immedok(), is_leaveok() and is_scrollok() return TRUE
+   or FALSE. is_idlok() and is_idcok() are provided for compatibility with
+   other curses implementations, and always return FALSE. All others
+   return OK on success and ERR on error.

+                int dst_bc, int _overlay)
+
+### Description
+
+   overlay() and overwrite() copy all the text from src_w into dst_w.
+   The windows need not be the same size. Those characters in the source
+   window that intersect with the destination window are copied, so that
+   the characters appear in the same physical position on the screen.
+   The difference between the two functions is that overlay() is non-
+   destructive (blanks are not copied) while overwrite() is destructive
+   (blanks are copied).
+
+   copywin() is similar, but doesn't require that the two windows
+   overlap. The arguments src_tc and src_tr specify the top left corner
+   of the region to be copied. dst_tc, dst_tr, dst_br, and dst_bc
+   specify the region within the destination window to copy to. The
+   argument "overlay", if TRUE, indicates that the copy is done non-
+   destructively (as in overlay()); blanks in the source window are not
+   copied to the destination window. When overlay is FALSE, blanks are
+   copied.
+
+### Return Value
+
+   All functions return OK on success and ERR on error.

+
+### Description
+
+   A pad is a special kind of window, which is not restricted by the
+   screen size, and is not necessarily associated with a particular part
+   of the screen. You can use a pad when you need a large window, and
+   only a part of the window will be on the screen at one time. Pads are
+   not refreshed automatically (e.g., from scrolling or echoing of
+   input). You can't call wrefresh() with a pad as an argument; use
+   prefresh() or pnoutrefresh() instead. Note that these routines
+   require additional parameters to specify the part of the pad to be
+   displayed, and the location to use on the screen.
+
+   newpad() creates a new pad data structure.
+
+   subpad() creates a new sub-pad within a pad, at position (begy,
+   begx), with dimensions of nlines lines and ncols columns. This
+   position is relative to the pad, and not to the screen as with
+   subwin. Changes to either the parent pad or sub-pad will affect both.
+   When using sub-pads, you may need to call touchwin() before calling
+   prefresh().
+
+   pnoutrefresh() copies the specified pad to the virtual screen.
+
+   prefresh() calls pnoutrefresh(), followed by doupdate().
+
+   These routines are analogous to wnoutrefresh() and wrefresh(). (py,
+   px) specifies the upper left corner of the part of the pad to be
+   displayed; (sy1, sx1) and (sy2, sx2) describe the screen rectangle
+   that will contain the selected part of the pad.
+
+   pechochar() is functionally equivalent to addch() followed by a call
+   to prefresh(), with the last-used coordinates and dimensions.
+   pecho_wchar() is the wide-character version.
+
+   is_pad() reports whether the specified window is a pad.
+
+### Return Value
+
+   All functions except is_pad() return OK on success and ERR on error.
+
+### Portability

+### Synopsis
+
+    int PDC_set_blink(bool blinkon);
+    int PDC_set_bold(bool boldon);
+    void PDC_set_title(const char *title);
+
+### Description
+
+   PDC_set_blink() toggles whether the A_BLINK attribute sets an actual
+   blink mode (TRUE), or sets the background color to high intensity
+   (FALSE). The default is platform-dependent (FALSE in most cases). It
+   returns OK if it could set the state to match the given parameter,
+   ERR otherwise.
+
+   PDC_set_bold() toggles whether the A_BOLD attribute selects an actual
+   bold font (TRUE), or sets the foreground color to high intensity
+   (FALSE). It returns OK if it could set the state to match the given

+### Synopsis
+
+    int printw(const char *fmt, ...);
+    int wprintw(WINDOW *win, const char *fmt, ...);
+    int mvprintw(int y, int x, const char *fmt, ...);
+    int mvwprintw(WINDOW *win, int y, int x, const char *fmt,...);
+    int vwprintw(WINDOW *win, const char *fmt, va_list varglist);
+    int vw_printw(WINDOW *win, const char *fmt, va_list varglist);
+
+### Description
+
+   The printw() functions add a formatted string to the window at the
+   current or specified cursor position. The format strings are the same
+   as used in the standard C library's printf(). (printw() can be used
+   as a drop-in replacement for printf().)
+
+   The duplication between vwprintw() and vw_printw() is for historic
+   reasons. In PDCurses, they're the same.
+
+### Return Value
+
+   All functions return the number of characters printed, or ERR on
+   error.
+
+### Portability

+
+### Synopsis
+
+    int refresh(void);
+    int wrefresh(WINDOW *win);
+    int wnoutrefresh(WINDOW *win);
+    int doupdate(void);
+    int redrawwin(WINDOW *win);
+    int wredrawln(WINDOW *win, int beg_line, int num_lines);
+
+### Description
+
+   wrefresh() copies the named window to the physical terminal screen,
+   taking into account what is already there in order to optimize cursor
+   movement. refresh() does the same, using stdscr. These routines must
+   be called to get any output on the terminal, as other routines only
+   manipulate data structures. Unless leaveok() has been enabled, the
+   physical cursor of the terminal is left at the location of the
+   window's cursor.
+
+   wnoutrefresh() and doupdate() allow multiple updates with more
+   efficiency than wrefresh() alone. wrefresh() works by first calling
+   wnoutrefresh(), which copies the named window to the virtual screen.
+   It then calls doupdate(), which compares the virtual screen to the
+   physical screen and does the actual update. A series of calls to
+   wrefresh() will result in alternating calls to wnoutrefresh() and
+   doupdate(), causing several bursts of output to the screen. By first
+   calling wnoutrefresh() for each window, it is then possible to call
+   doupdate() only once.
+
+   In PDCurses, redrawwin() is equivalent to touchwin(), and wredrawln()
+   is the same as touchline(). In some other curses implementations,
+   there's a subtle distinction, but it has no meaning in PDCurses.
+
+### Return Value

+   All functions return OK on success and ERR on error.

+### Synopsis
+
+    int scroll(WINDOW *win);
+    int scrl(int n);
+    int wscrl(WINDOW *win, int n);
+
+### Description
+
+   scroll() causes the window to scroll up one line. This involves
+   moving the lines in the window data strcture.
+
+   With a positive n, scrl() and wscrl() scroll the window up n lines
+   (line i + n becomes i); otherwise they scroll the window down n
+   lines.
+
+   For these functions to work, scrolling must be enabled via
+   scrollok(). Note also that scrolling is not allowed if the supplied
+   window is a pad.
+
+### Return Value
+
+   All functions return OK on success and ERR on error.
+
+### Portability

+
+### Description
+
+   These functions manipulate a window that contain Soft Label Keys
+   (SLK). To use the SLK functions, a call to slk_init() must be made
+   BEFORE initscr() or newterm(). slk_init() removes 1 or 2 lines from
+   the useable screen, depending on the format selected.
+
+   The line(s) removed from the screen are used as a separate window, in
+   which SLKs are displayed.
+
+   slk_init() requires a single parameter which describes the format of
+   the SLKs as follows:
+
+   0       3-2-3 format
+   1       4-4 format
+   2       4-4-4 format (ncurses extension)
+   3       4-4-4 format with index line (ncurses extension)
+   2 lines used
+   55      5-5 format (pdcurses format)
+
+   slk_refresh(), slk_noutrefresh() and slk_touch() are analogous to
+   refresh(), noutrefresh() and touch().
+
+### Return Value
+
+   All functions return OK on success and ERR on error.
+
+### Portability

+    int touchoverlap(const WINDOW *win1, WINDOW *win2);
+
+### Description
+
+   touchwin() and touchline() throw away all information about which
+   parts of the window have been touched, pretending that the entire
+   window has been drawn on. This is sometimes necessary when using
+   overlapping windows, since a change to one window will affect the
+   other window, but the records of which lines have been changed in the
+   other window will not reflect the change.
+
+   untouchwin() marks all lines in the window as unchanged since the
+   last call to wrefresh().
+
+   wtouchln() makes n lines in the window, starting at line y, look as
+   if they have (changed == 1) or have not (changed == 0) been changed
+   since the last call to wrefresh().
+
+   is_linetouched() returns TRUE if the specified line in the specified
+   window has been changed since the last call to wrefresh().
+
+   is_wintouched() returns TRUE if the specified window has been changed
+   since the last call to wrefresh().
+
+   touchoverlap(win1, win2) marks the portion of win2 which overlaps
+   with win1 as modified.
+
+### Return Value

+   All functions return OK on success and ERR on error except
+   is_wintouched() and is_linetouched().

+
+### Description
+
+   newwin() creates a new window with the given number of lines, nlines
+   and columns, ncols. The upper left corner of the window is at line
+   begy, column begx. If nlines is zero, it defaults to LINES - begy;
+   ncols to COLS - begx. Create a new full-screen window by calling
+   newwin(0, 0, 0, 0).
+
+   delwin() deletes the named window, freeing all associated memory. In
+   the case of overlapping windows, subwindows should be deleted before
+   the main window.
+
+   mvwin() moves the window so that the upper left-hand corner is at
+   position (y,x). If the move would cause the window to be off the
+   screen, it is an error and the window is not moved. Moving subwindows
+   is allowed.
+
+   subwin() creates a new subwindow within a window. The dimensions of
+   the subwindow are nlines lines and ncols columns. The subwindow is at
+   position (begy, begx) on the screen. This position is relative to the
+   screen, and not to the window orig. Changes made to either window
+   will affect both. When using this routine, you will often need to
+   call touchwin() before calling wrefresh().
+
+   derwin() is the same as subwin(), except that begy and begx are
+   relative to the origin of the window orig rather than the screen.
+   There is no difference between subwindows and derived windows.
+
+   mvderwin() moves a derived window (or subwindow) inside its parent
+   window. The screen-relative parameters of the window are not changed.
+   This routine is used to display different parts of the parent window
+   at the same physical position on the screen.
+
+   dupwin() creates an exact duplicate of the window win.
+
+   wgetparent() returns the parent WINDOW pointer for subwindows, or NULL
+   for windows having no parent.
+
+   wsyncup() causes a touchwin() of all of the window's parents.
+
+   If syncok() is called with a second argument of TRUE, this causes a
+   wsyncup() to be called every time the window is changed.
+
+   is_subwin() reports whether the specified window is a subwindow,
+   created by subwin() or derwin().
+
+   is_syncok() reports whether the specified window is in syncok mode.
+
+   wcursyncup() causes the current cursor position of all of a window's
+   ancestors to reflect the current cursor position of the current
+   window.
+
+   wsyncdown() causes a touchwin() of the current window if any of its
+   parent's windows have been touched.
+
+   resize_window() allows the user to resize an existing window. It
+   returns the pointer to the new window, or NULL on failure.
+
+   wresize() is an ncurses-compatible wrapper for resize_window(). Note
+   that, unlike ncurses, it will NOT process any subwindows of the
+   window. (However, you still can call it _on_ subwindows.) It returns
+   OK or ERR.
+
+   PDC_makenew() allocates all data for a new WINDOW * except the actual
+   lines themselves. If it's unable to allocate memory for the window
+   structure, it will free all allocated memory and return a NULL
+   pointer.
+
+   PDC_makelines() allocates the memory for the lines.
+
+   PDC_sync() handles wrefresh() and wsyncup() calls when a window is
+   changed.
+
+### Return Value
+
+   newwin(), subwin(), derwin() and dupwin() return a pointer to the new
+   window, or NULL on failure. delwin(), mvwin(), mvderwin() and
+   syncok() return OK or ERR. wsyncup(), wcursyncup() and wsyncdown()
+   return nothing.
+
+   is_subwin() and is_syncok() returns TRUE or FALSE.
+
+### Errors
+
+   It is an error to call resize_window() before calling initscr().
+   Also, an error will be generated if we fail to create a newly sized
+   replacement window for curscr, or stdscr. This could happen when
+   increasing the window size. NOTE: If this happens, the previously
+   successfully allocated windows are left alone; i.e., the resize is
+   NOT cancelled for those windows.

+/* A 'directory separator' is a byte that equals 0x2F ('solidus' or more
+ * commonly 'forward slash') or 0x5C ('reverse solidus' or more commonly
+ * 'backward slash'). The byte 0x5C may look different from a backward slash
+ * in some locales; for example, it looks the same as a Yen sign in Japanese
+ * locales and a Won sign in Korean locales. Despite its appearance, it still
+ * functions as a directory separator.
+ *
+ * A 'path' comprises an optional DOS drive letter with a colon, and then an
+ * arbitrary number of possibily empty components, separated by non-empty
+ * sequences of directory separators (in other words, consecutive directory
+ * separators are treated as a single one). A path that comprises an empty
+ * component denotes the current working directory.
+ *
+ * An 'absolute path' comprises at least two components, the first of which
+ * is empty.
+ *
+ * A 'relative path' is a path that is not an absolute path. In other words,
+ * it either comprises an empty component, or begins with a non-empty
+ * component.
+ *
+ * POSIX doesn't have a concept about DOS drives. A path that does not have a
+ * drive letter starts from the same drive as the current working directory.
+ *
+ * For example:
+ * (Examples without drive letters match POSIX.)
+ *
+ *   Argument                 dirname() returns        basename() returns
+ *   --------                 -----------------        ------------------

+You may use this code in any way you wish, and it is free.  No warrantee.

+------------------------------------------------------------------------------
+
+  The original version of this file was downloaded from Bob Jenkins website:
+
+     http://burtleburtle.net/bob/rand/isaacafa.html
+
+  The isaac and randinit functions have been slightly modified to silence
+  warnings in modern compilers; the get_entropy and get_random_bytes have
+  been added.
+
+  These changes were made by R M Yorston and are also dedicated to the
+  public domain.

+   The former two functions operate on STRING with length LENGTH,

+
+   re_match() matches the compiled pattern in BUFP against the string,

+   the first STOP characters of the concatenation of the strings should be
+   concerned.
+
+   If REGS is not NULL, and BUFP->no_sub is not set, the offsets of the match
+   and all groups is stroed in REGS.  (For the "_2" variants, the offsets are
+   computed relative to the concatenation, not relative to the individual
+   strings.)

+ * readConsoleInput_utf8 behaves similar enough to ReadConsoleInputA when

+ * - It depend on the console CP, while we use ReadConsoleInputW internally.
+ * - ReadConsoleInputA with Console CP of UTF8 (65001) is buggy:
+ *   - Doesn't work on Windows 7 (reads 0 or '?' for non-ASCII codepoints).
+ *   - When used at the cmd.exe console - but not Windows Terminal:
+ *     sometimes only key-up events arrive without the expected prior key-down.
+ *     Seems to depend both on the console CP and the entered/pasted codepoint.
+ *   - If reading one record at a time (which is how we use it), then input
+ *     codepoints of U+0800 or higher crash the console/terminal window.
+ *     (tested on Windows 10.0.19045.3086: console and Windows Terminal 1.17)
+ *     Example: U+0C80 (UTF8: 0xE0 0xB2 0x80): "ಀ"
+ *     Example: U+1F600 (UTF8: 0xF0 0x9F 0x98 0x80): "😀"
+ *   - If reading more than one record at a time:
+ *     - Unknown whether it can still crash in some cases (was not observed).
+ *     - Codepoints above U+FFFF are broken, and arrive as
+ *       U+FFFD REPLACEMENT CHARACTER "�"
+ * - Few more codepoints to test the issues above (and below):
+ *   - U+0500 (UTF8: 0xD4, 0x80): "Ԁ"  (OK in UTF8 CP, else maybe no key-down)
+ *   - U+07C0 (UTF8: 0xDF, 0x80): "߀"  (might exhibit missing key-down)
+ *
+ * So this function uses ReadConsoleInputW and then delivers it as UTF8:
+ * - Works with any console CP, in Windows terminal and Windows 7/10 console.
+ * - Surrogate pairs are combined and delivered as a single UTF8 codepoint.
+ *   - Ignore occasional intermediate control events between the halfs.
+ *   - If we can't find the 2nd half, or if for some reason we get a 2nd half
+ *     wiithout the 1st, deliver the half we got as UTF8 (a-la WTF8).
+ * - The "sometimes key-down is missing" issue at the cmd.exe console happens
+ *   also when using ReadConsoleInputW (for U+0080 or higher), so handle it.
+ *   This can also happen with surrogate pairs.
+ * - Up to 4-bytes state is maintained for a single UTF8 codepoint buffer.
+ *
+ * Gotchas (could be solved, but currently there's no need):
+ * - We support reading one record at a time, else fail - to make it obvious.
+ * - We have a state which is hidden from PeekConsoleInput - so not in sync.
+ * - We don't deliver key-up events in some cases: when working around
+ *   the "missing key-down" issue, and with combined surrogate halfs value.

+// potential data-loss if they differ, we could convert it to wchar_t and
+// write it using WriteConsoleW. This should prevent all output data-loss.
+// care should be taken with DBCS codepages (e.g. 936) or other multi-byte
