  * Rearrange the code for the world file feature
  Better better organisation of concerns for it to be in the Install
  module rather than in Main which is mostly concerned with command
  line handling.

    M ./Distribution/Client/Install.hs -2 +25
    M ./Distribution/Client/World.hs -42 +60
    M ./Main.hs -19 +2
