Basically, what the subject says:

I'm working on some automation and I need a perl script to launch another script and then write some data into that script's STDIN. I can't do this with command-line arguments, and I can't have a prepared file that I would just pipe in because I need to get some output from the second script first.

My google-fu has not been strong enough, although this seems like a pretty basic question...
