+
+Easy and safe casting from one type to another in Go
+
+Don’t Panic! ... Cast
+
+## What is Cast?
+
+Cast is a library to convert between different go types in a consistent and easy way.
+
+Cast provides simple functions to easily convert a number to a string, an
+interface into a bool, etc. Cast does this intelligently when an obvious
+conversion is possible. It doesn’t make any attempts to guess what you meant,
+for example you can only convert a string to an int when it is a string
+representation of an int such as “8”. Cast was developed for use in
+[Hugo](http://hugo.spf13.com), a website engine which uses YAML, TOML or JSON
+for meta data.
+
+## Why use Cast?
+
+When working with dynamic data in Go you often need to cast or convert the data
+from one type into another. Cast goes beyond just using type assertion (though
+it uses that when possible) to provide a very straightforward and convenient
+library.
+
+If you are working with interfaces to handle things like dynamic content
+you’ll need an easy way to convert an interface into a given type. This
+is the library for you.
+
+If you are taking in data from YAML, TOML or JSON or other formats which lack
+full types, then Cast is the library for you.
+
+## Usage
+
+Cast provides a handful of To_____ methods. These methods will always return
+the desired type. **If input is provided that will not convert to that type, the
+0 or nil value for that type will be returned**.
+
+Cast also provides identical methods To_____E. These return the same result as
+the To_____ methods, plus an additional error which tells you if it successfully
+converted. Using these methods you can tell the difference between when the
+input matched the zero value or when the conversion failed and the zero value
+was returned.
+
+The following examples are merely a sample of what is available. Please review
+the code for a complete set.
+
+### Example ‘ToString’:
+
+    cast.ToString("mayonegg")         // "mayonegg"
+    cast.ToString(8)                  // "8"
+    cast.ToString(8.31)               // "8.31"
+    cast.ToString([]byte("one time")) // "one time"
+    cast.ToString(nil)                // ""
+
+	var foo interface{} = "one more time"
+    cast.ToString(foo)                // "one more time"
+
+
+### Example ‘ToInt’:
+
+    cast.ToInt(8)                  // 8
+    cast.ToInt(8.31)               // 8
+    cast.ToInt("8")                // 8
+    cast.ToInt(true)               // 1
+    cast.ToInt(false)              // 0
+
+	var eight interface{} = 8
+    cast.ToInt(eight)              // 8
+    cast.ToInt(nil)                // 0
