 Who is this tutorial for?
 -------------------------

 This tutorial is for people who want to learn the ropes of chapel without having to hear about what fiber mixture the ropes are, or how they were braided, or how the braid configurations differ between one another.
 It won't teach you how to develop amazingly performant code, and it's not exhaustive. 
 Refer to the [language specification](http://chapel.cray.com/language.html) and the [library documentation](http://chapel.cray.com/docs/latest/) for more details.

 The Chapel language is still in-development (version 1.11.0), so there are occasional hiccups with performance and language features.
 The more information you give the Chapel development team about issues you encounter or features you would like to see, the better the language becomes.
 Feel free to email the team and other developers through the [sourceforge email lists](https://sourceforge.net/p/chapel/mailman).

 You will need to ```source util/setchplenv.EXT``` from the chapel directory every time your terminal starts so its suggested that you drop that command in a script that will get executed on startup (like .bashrc).
