Programmers know package managers as an easy way of distributing reusable libraries and plugins. By using one, you're literally saving yourself a lot of time spent setting things up, upgrading things, or even pushing things to production servers. A good package manager can be a life saver!
You'll find - if you care to dig deep enough - that there is no shortage of package managers on the web. Every programming language has at least two. Are you're a software developer who is still using traditional methods of handling libraries? It's much easier to stay in control of dependencies since you just change a number in a text file and execute a command. The package manager is doing all the work for you.
Thanks, Wikipedia, for the image!
