Instead of throwing the syntax errors with their source file location and needing to then catch them and call a `prettyErrorMessage` function in order to get the formatted error message, now syntax errors know how to pretty-print themselves (their `toString` method gets overridden). An intermediate `catch` & re-`throw` is needed at the level of `CoffeeScript.compile` and friends. But the benefit of this approach is that now libraries that use the `CoffeeScript` object directly don't need to bother catching the possible compilation errors and calling a special function in order to get the nice error messages; they can just print the error itself (or let it bubble up) and the error will know how to pretty-print itself.

CoffeeScript is a little language that compiles into JavaScript.
Install Node.js, and then the CoffeeScript compiler:
sudo bin/cake install
Or, if you have the Node Package Manager installed:
npm install -g coffee-script
(Leave off the -g if you don't wish to install globally.)
Execute a script:
coffee /path/to/script.coffee
Compile a script:
coffee -c /path/to/script.coffee
For documentation, usage, and examples, see:
