This should be so simple, but I'm really struggling...

I have an install script (win2000) which asks a few questions, runs a few system() commands, produces output to stdout and stderr. I need everything that's printed to the screen to also go to a single file, retaining the order it's generated.

doing

perl scriptname.pl >outfile
redirects ALL output to the file, meaning my "where do you want to install this?" question isn't printed, thus the user has no idea what he's being asked.

Think I need something like UNIX's tee function, or even some software which captures everything in a DOS box.

Of course, the reason I'm here is that a pure Perl solution would be ideal. I can redirect STDOUT and STDERR to a file easily, but need to keep it all going to screen as well!

TIA
