 This package is dual licensed.  You can either choose to license it under
 the original terms which were:
 .
 Unlimited distribution and/or modification is allowed as long as this
 copyright notice remains intact.
 .
 Or the standard Perl terms:
 .
 This module is free software; you can redistribute it and/or modify it
 under the terms of the Artistic License. For details, see the full
 text of the license in the file "Artistic" that should have been provided
 with the version of perl you are using.
 .
 This program is distributed in the hope that it will be useful, but
 without any warranty; without even the implied warranty of merchantability
 or fitness for a particular purpose.
 .
 This module, ReadKey, provides ioctl control for terminals and Win32
 consoles so the input modes can be changed (thus allowing reads of a single
 character at a time), and also provides non-blocking reads of stdin, as well
 as several other terminal related features, including retrieval/modification
 of the screen size, and retrieval/modification of the control characters.
 Installation requires MakeMaker 3.5 or higher (MakeMaker 3.7 is included
 with perl 5.001, so now is a good time to upgrade if you haven't already.)
 .
 To install, unpack somewhere, type "perl Makefile.PL", and then "make test".
 If the compilation and the tests are successful, then change to root and run
 "make install".
 .
 As of 2.17 the interactive test has been removed as the default for the
 convenience of automated installers, CPAN-Testers and so on.  The non
 interactive tests whilst confirming that the module has built correctly
 and has a good chance of working correctly cannot determine whether the
 effect as observed on the screen is correct so you might want to run:
 .
 perl -Mblib example/test.pl interactive
 .
 before you run 'make install'.
 .
 Also from 2.17 this module has to provide its own support for compilers
 that can't take function prototypes as with Perl 5.8.0 this last vestige
 of support for non-ANSI compilers will disappear.  The requirement for
 an ANSI C compiler has been present since Perl 5.005 so it is likely that
 at some point in the future this module will follow that requirement too.
 If you have any difficulties with older Perl's please contact the maintainer.
 .
 The module has support for Win32 since version 2.10. Version 2.17 has been
 tested with ActivePerl build 623 and Visual Studio 6 and found to work
 as expected, but do not be surprised if it fails with another compiler
 or distribution.  There are  some limitations, with the ReadLine call
 being unavailable, and ReadKey possibly generating bad results if you
 are reading from multiple consoles, and key repeat is used.  For Win32
 users without a C compiler there is a precompiled version of this module
 available as a package for ActivePerl, it is probably a few versions
 behind the latest release but has been reported to work well.
 .
 VERY IMPORTANT: In 2.00, the ReadKey/ReadLine arguments changed. Now, if
 you want a call that is non-blocking and returns immediately if no
 character is waiting, please call it with -1, instead of 1. Positive
 arguments now indicate a timeout, so 1 would wait a second before timing
 out.
 .
 As older versions will accept -1, it is reccomended to change all code
 that uses ReadMode.
 .
 The terminal mode function is controlled by the "ReadMode" function, which
 takes a single numeric argument, and an optional filehandle. This argument
 should be one of the following:
 .
 0: (Reset) Restore original settings.
 .
 1: (Cooked) Change to what is commonly the default mode, echo on,
 buffered, signals enabled, Xon/Xoff possibly enabled, and 8-bit mode
 possibly disabled.
 .
 2: (Cooked-Invisible) Same as 1, just with echo off. Nice for reading
 passwords.
 .
 3: (CBreak) Echo off, unbuffered, signals enabled, Xon/Xoff possibly
 enabled, and 8-bit mode possibly enabled.
 .
 4: (Raw) Echo off, unbuffered, signals disabled, Xon/Xoff disabled,
 and 8-bit mode possibly disabled.
 .
 5: (Really-Raw) Echo off, unbuffered, signals disabled, Xon/Xoff
 disabled, 8-bit mode enabled if parity permits, and CR to CR/LF
 translation turned off.
 .
 If you just need to read a key at a time, then modes 3 or 4 are probably
 sufficient. Mode 4 is a tad more flexible, but needs a bit more work to
 control. If you use ReadMode 3, then you should install a SIGINT or END
 handler to reset the terminal (via ReadMode 0) if the user aborts the
 program via ^C. (For any mode, an END handler consisting of "ReadMode 0" is
 actually a good idea.)
 .
 Non-blocking support is provided via the ReadKey and ReadLine functions. If
 they are passed no argument, or an argument of zero, they will act like a
 normal getc(STDIN) or scalar(). If they are passed a negative
 argument, then they will immediatly return undef if no input is present. If
 passed a positive argument, then they will wait until that time in seconds
 has passed before returning undef. In most situations, you will probably
 want to use "ReadKey -1".
 .
 Note that a non-blocking ReadLine probably won't do what you expect,
 although it is perfectly predictable, and that the ReadMode will have to be
 1 or 0 for it to make sense at all.
 .
 A routine is also provided to get the current terminal size,
 "GetTerminalSize". This will either return a four value array containing the
 width and height of the screen in characters and then in pixels, or nothing
 ( if the OS can't return that info). SetTerminalSize allows the stored
