I am trying to clean my installation up a bit, so I decided to clean up my packages a bit. However, I'm having trouble with that: My wish is to make `apt-get` list all packages installed by me. If I list every package, I also see the dependencies of my packages although I am not interested in those. For example, I want to see that I installed `lightyears` but I do not want to see the packages installed alongside, like `python-numpy or python-pygame`. Is there a way to do this?
