+// STORY
+//  You're curious about the richter scales. When reporters
+//  say: "There's been a 5.5 magnitude earthquake",
+//
+//  You want to know what that means.
+//
+//  So, you've decided to write a program to do that for you.
+//
+// EXERCISE
+//  1. Get the earthquake magnitude from the command-line.
+//  2. Display its corresponding description.
+//
+// ---------------------------------------------------------
+// MAGNITUDE                    DESCRIPTION
+// ---------------------------------------------------------
+// Less than 2.0                micro
+// 2.0 to less than 3.0         very minor
+// 3.0 to less than 4.0         minor
+// 4.0 to less than 5.0         light
+// 5.0 to less than 6.0         moderate
+// 6.0 to less than 7.0         strong
+// 7.0 to less than 8.0         major
+// 8.0 to less than 10.0        great
+// 10.0 or more                 massive
+//
+// EXPECTED OUTPUT
+//  go run main.go
+//    Give me the magnitude of the earthquake.
+//
+//  go run main.go ABC
+//    I couldn't get that, sorry.
