Package ShellCheck

Shell script analysis tool

https://github.com/koalaman/shellcheck

The goals of ShellCheck are:

* To point out and clarify typical beginner's syntax issues,
  that causes a shell to give cryptic error messages.

* To point out and clarify typical intermediate level semantic problems,
  that causes a shell to behave strangely and counter-intuitively.

* To point out subtle caveats, corner cases and pitfalls, that may cause an
  advanced user's otherwise working script to fail under future circumstances.
