[erlang-questions] how to make beautifulll code of this working code

[Garrett Smith]

Personally I find the Erlang docs excellent, so this:

http://erlang.org/doc/man/re.html#split-2

Roelof, I recommend that you spend some cycles reading these as a
matter of course when you're using a function. The docs will help you
get things right and you'll start to absorb some Erlang zen. The list
is great to help after you've done that and still have questions.

This link provides an index, which might also be helpful for finding
the right module and function in the first place:
