GNU app usage along with a closed source app
My program requires plink app which is distributed under the GNU license. plink is an executable and it will be used externally from my app - i.e. 
handle = CreateProcess("plink.exe", ....) and so on...

My intention is to sell my app and because it requires plink i will distribute it along with the installation.

The general question is can i do this legally?
