The wperl.exe command under Windows starts Perl without attaching it to a console. This means that if you associate for example the file extension .wpl with wperl.exe, double-clicking test.wpl will not pop up a console window with text scrolling by. This is very convenient if your Perl script is written using Win32::GUI or some other windowing toolkit.

Using wperl.exe and thus not having a console attached also has a drawback - STDIN,STDOUT and STDERR are not available, so you will need to reopen them to some log files if you output any text via print or warn.
