+// A set of comprehensive testing tools for use with the normal Go testing system.
+//
+// Example Usage
+//
+// The following is a complete example using assert in a standard test function:
+//    import (
+//      "testing"
+//      "github.com/stretchr/testify/assert"
+//    )
+//
+//    func TestSomething(t *testing.T) {
+//
+//      var a string = "Hello"
+//      var b string = "Hello"
+//
+//      assert.Equal(t, a, b, "The two words should be the same.")
+//
+//    }
+//
+// Assertions
+//
+// Assertions allow you to easily write test code, and are global funcs in the `assert` package.
+// All assertion functions take, as the first argument, the `*testing.T` object provided by the
+// testing framework. This allows the assertion funcs to write the failings and other details to
+// the correct place.
+//
+// Every assertion function also takes an optional string message as the final argument,
+// allowing custom error messages to be appended to the message the assertion method outputs.
+//
+// Here is an overview of the assert functions:
+//
+//    assert.Equal(t, expected, actual [, message [, format-args])
+//
+//    assert.NotEqual(t, notExpected, actual [, message [, format-args]])
+//
+//    assert.True(t, actualBool [, message [, format-args]])
+//
+//    assert.False(t, actualBool [, message [, format-args]])
+//
+//    assert.Nil(t, actualObject [, message [, format-args]])
+//
+//    assert.NotNil(t, actualObject [, message [, format-args]])
+//
+//    assert.Empty(t, actualObject [, message [, format-args]])
+//
+//    assert.NotEmpty(t, actualObject [, message [, format-args]])
+//
+//    assert.Error(t, errorObject [, message [, format-args]])
+//
+//    assert.NoError(t, errorObject [, message [, format-args]])

+//    assert.Implements(t, (*MyInterface)(nil), new(MyObject) [,message [, format-args]])
+//
+//    assert.IsType(t, expectedObject, actualObject [, message [, format-args]])
+//
+//    assert.Contains(t, string, substring [, message [, format-args]])
