-# errwrap
-
-`errwrap` is a package for Go that formalizes the pattern of wrapping errors
-and checking if an error contains another error.
-
-There is a common pattern in Go of taking a returned `error` value and
-then wrapping it (such as with `fmt.Errorf`) before returning it. The problem
-with this pattern is that you completely lose the original `error` structure.
-
-Arguably the _correct_ approach is that you should make a custom structure
-implementing the `error` interface, and have the original error as a field
-on that structure, such [as this example](http://golang.org/pkg/os/#PathError).
-This is a good approach, but you have to know the entire chain of possible
-rewrapping that happens, when you might just care about one.
-
-`errwrap` formalizes this pattern (it doesn't matter what approach you use
-above) by giving a single interface for wrapping errors, checking if a specific
-error is wrapped, and extracting that error.
-
-## Installation and Docs
-
-Install using `go get github.com/hashicorp/errwrap`.
-
-Full documentation is available at
-http://godoc.org/github.com/hashicorp/errwrap
-
-## Usage
-
-#### Basic Usage
-
-Below is a very basic example of its usage:
-
-```go
-// A function that always returns an error, but wraps it, like a real
-// function might.
-func tryOpen() error {
-	_, err := os.Open("/i/dont/exist")
-	if err != nil {
-		return errwrap.Wrapf("Doesn't exist: {{err}}", err)
-	}
-
-	return nil
-}
-
-func main() {
-	err := tryOpen()
-
-	// We can use the Contains helpers to check if an error contains
-	// another error. It is safe to do this with a nil error, or with
-	// an error that doesn't even use the errwrap package.
-	if errwrap.Contains(err, "does not exist") {
-		// Do something
-	}
-	if errwrap.ContainsType(err, new(os.PathError)) {
-		// Do something
-	}
-
-	// Or we can use the associated `Get` functions to just extract
-	// a specific error. This would return nil if that specific error doesn't
-	// exist.
-	perr := errwrap.GetType(err, new(os.PathError))
-}
-```
-
-#### Custom Types
-
-If you're already making custom types that properly wrap errors, then
-you can get all the functionality of `errwraps.Contains` and such by
-implementing the `Wrapper` interface with just one function. Example:
-
-```go
-type AppError {
-  Code ErrorCode
-  Err  error
-}
-
-func (e *AppError) WrappedErrors() []error {
-  return []error{e.Err}
-}
-```
-
-Now this works:
-
-```go
-err := &AppError{Err: fmt.Errorf("an error")}
-if errwrap.ContainsType(err, fmt.Errorf("")) {
-	// This will work!
-}
-```

-
-`go-multierror` is a package for Go that provides a mechanism for
-representing a list of `error` values as a single `error`.
-
-This allows a function in Go to return an `error` that might actually
-be a list of errors. If the caller knows this, they can unwrap the
-list and access the errors. If the caller doesn't know, the error
-formats to a nice human-readable format.
-
-`go-multierror` implements the
-[errwrap](https://github.com/hashicorp/errwrap) interface so that it can
-be used with that library, as well.
-
-## Installation and Docs
-
-Install using `go get github.com/hashicorp/go-multierror`.
-
-Full documentation is available at
-http://godoc.org/github.com/hashicorp/go-multierror
-
-## Usage
-
-go-multierror is easy to use and purposely built to be unobtrusive in
-existing Go applications/libraries that may not be aware of it.
-
-**Building a list of errors**
-
-The `Append` function is used to create a list of errors. This function
-behaves a lot like the Go built-in `append` function: it doesn't matter
-if the first argument is nil, a `multierror.Error`, or any other `error`,
-the function behaves as you would expect.
-
-```go
-var result error
-
-if err := step1(); err != nil {
-	result = multierror.Append(result, err)
-}
-if err := step2(); err != nil {
-	result = multierror.Append(result, err)
-}
-
-return result
-```
-
-**Customizing the formatting of the errors**
-
-By specifying a custom `ErrorFormat`, you can customize the format
-of the `Error() string` function:
-
-```go
-var result *multierror.Error
-
-// ... accumulate errors here, maybe using Append
-
-if result != nil {
-	result.ErrorFormat = func([]error) string {
-		return "errors!"
-	}
-}
-```
-
-**Accessing the list of errors**
-
-`multierror.Error` implements `error` so if the caller doesn't know about
-multierror, it will work just fine. But if you're aware a multierror might
-be returned, you can use type switches to access the list of errors:
-
-```go
-if err := something(); err != nil {
-	if merr, ok := err.(*multierror.Error); ok {
-		// Use merr.Errors
-	}
-}
-```
-
-**Returning a multierror only if there are errors**
-
-If you build a `multierror.Error`, you can use the `ErrorOrNil` function
-to return an `error` implementation only if there are errors to return:
-
-```go
-var result *multierror.Error
-
-// ... accumulate errors here
-
-// Return the `error` only if errors were added to the multierror, otherwise
-// return nil since there are no errors.
-return result.ErrorOrNil()
-```
