title: Apt-get installers: how does it works
body: <p>I need to learn new aspect of development: making apt-get installers. Because of it, I need to find out, how it works. I tried to search information about it, but 90% of it is apt-get man's. </p>
  
  <p>For example: user prints <code>sudo apt-get install package_name</code>, and what? Is there installation script on server from <code>sources.list</code> file? If yes, how does it execute on client's computer? </p>
  
  <p>I'll be glad to learn it with your help. May be it's stupid question, but I really can't find necessary information about this topic. Thank you!</p>
