+haskell-ShellCheck - shell script analysis tool
+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.
