input path. Windows Forms and WPF (`require "System.Windows.Forms"`, `"PresentationFramework"`)
come from the Windows Desktop runtime, which `ir` references whenever it is built for Windows
(`-p:IronRubyWindowsDesktop=false` leaves it out); on Linux and macOS they do not exist.
[`Samples/Notepad`](Samples/Notepad/notepad.rb) is Windows Notepad written that way, in Ruby
(`Samples\Notepad\notepad.cmd`); its test drives it with nobody at the keyboard and runs in CI.
macOS is untested.

rem ir.exe is a console program, so Windows gives it a console window. "start /b" leaves
rem that console to ir.exe alone once this batch file has ended, and notepad.rb then
rem lets go of it, which closes the window. To keep the console for Ruby's output, run
rem ..\..\ir.cmd notepad.rb instead. The build is chosen as ir.cmd chooses it.
