title: Linux: Remove application settings after program is uninstalled?
body: <p>I'm writing a program for Linux that stores its data and settings in the home directory (e.g. /home/username/.program-name/stuff.xml). The data can take up 100 MB and more.</p>
  
  <p>I've always wondered what should happen with the data and the settings when the system admin removes the program. Should I then delete these files from every (!) home directory, or should I just leave them alone? Leaving hundreds of MB in the home directories seems quite wasteful...</p>
