Haskell is a very elegant language, and its pure functions are very appealing. However, one of the things that a person is wont to do when learning a new language is to write a toy program and, since all useful programs involve IO in some shape or another, things rapidly become ugly.

Most tutorials about Haskell IO skim over the practical aspects briefly, before diving into the depths of arcane theory. This tutorial aims to give you 'what you need' to start writing useful Haskell programs, without even attempting to explain what is going on (the latter is impossible, because I am a beginning Haskell programmer, and don't really know myself).

By the way, if you are an experienced Haskell programmer, and you have ever said something to the effect of "learn to program Haskell first, and worry about IO later", go away. Seriously, go away, you aren't welcome here.
