NetBSD itself is a very puristic operating system. It doesn't deliver much in its base except for the things really needed.
As such, it does not provide software you would usually install on your desktop system like a graphical editor, Firefox, etc.
In this task, you have to create a list of applications that are needed (only abstract, like "chatting"), and then propose a list of current software used for that and which one you would provide to a user.
The goal is to create a list of the applications, and a list of pros and cons of the single packages and why you would recommend them (or not).
