 On Windows, Scryer Prolog is easier to build inside a [MSYS2](https://www.msys2.org/)
 environment as some crates may require native C compilation. However, 
 the resulting binary does not need MSYS2 to run. When executing Scryer in a shell, it is recommended to use a more advanced shell than mintty (the default MSYS2 shell). The [Windows Terminal](https://github.com/microsoft/terminal) works correctly.
