Hi,
I have a ruby script which does some calculations and saves the result 
in a variable. Now this script should start another external application 
and pipe this variable's content into the gets() function of this 
external app. Any idea how I can do this?

greets

		        //\\/  ,,,  \//\\
		        |/\| ,;;;;;, |/\|
