+Description:
+  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.
