Having used Ubuntu for several years now, I've assembled a short list of scripts and packages that I always install on my computers. I would like to pack them up into a .deb to make it easier to get set up on a fresh OS installation. I'm imagining, for instance, one package that would install all of my custom BASH scripts that I've made for common tasks, and another one that would depend on other packages (like w64codecs) that I always install but forget that I need to until I go to do something and it's not there.

It doesn't even have to be by-the-book; I'm not looking to deploy these publicly. I'm just looking to roll up all these tasks into one sudo dpkg --install.

To quantify "simple" or "easy," I mean to say that I'm looking for the method with the fewest steps requiring the least technical knowledge and, most importantly, taking the least time.
