debian installing packages suggestion

[Jude DaShiell]

By way of example, installing the ghc compiler:
sudo apt install ghc|tee ghc.sug
answer no to install packages.
You get ghc.sug on your drive and can then look over the suggested packages to 
install.
If a problem happens later since you declined to install one of the suggested 
packages when you actually do install ghc, you at least have a list you can use 
to get the necessary packages to install on your drive.
