This can happen if you've renamed the file to ".php" instead of ".phar".

WARNING: If you wish to use this package directly from this archive, you need

         extract this archive, and include the autoloader.

\033[30;42m If you are reading this on a green background (and black text), then \033[0m
\033[30;42m this terminal supports color escape sequences, i.e. this package would \033[0m
\033[30;42m actually be useful in this environment. \033[0m

\033[32;44m In case your default background color is green, here's also a test \033[0m
\033[32;44m with a blue background (and green text). \033[0m

If above you see something like "[30;42m", then this terminal does not support
color escape sequences.

To add support for color escape sequences to Windows' command prompt,
install ANSICON.
See http://adoxa.hostmyway.net/ansicon/ or https://github.com/adoxa/ansicon.

HEREDOC;
        if (false !== getenv('ANSICON_VER')) {
            echo <<<HEREDOC

The presense of the "ANSICON_VER" environment variable suggests ANSICON is
already installed. If you are seeing "[30;42m" despite that, then ANSICON is
not really installed, and the command prompt is only pretending that it is.
