Exercism AWK track

AWK is a fun little language, widely used for text manipulation. One can express a lot of functionality in very few lines of code.

Spelling

The language is AWK.
The interpreter is awk or gawk.

Language variant

We'll use GNU awk in this track. It may not be the default awk in any platform, but it's in widespread use and has lots of builtin goodies.

Testing framework

Since I (@glennj) have spent a lot of time building up the bash track, I'll steal some of the learnings from it.

• Testing will be done with bats-core
• awk-test-runner was taken from the bash-test-runner.
