+[![GoDoc](https://godoc.org/github.com/smartystreets/assertions/internal/oglematchers?status.svg)](https://godoc.org/github.com/smartystreets/assertions/internal/oglematchers)
+
+`oglematchers` is a package for the Go programming language containing a set of
+matchers, useful in a testing or mocking framework, inspired by and mostly
+compatible with [Google Test][googletest] for C++ and
+[Google JS Test][google-js-test]. The package is used by the
+[ogletest][ogletest] testing framework and [oglemock][oglemock] mocking
+framework, which may be more directly useful to you, but can be generically used
+elsewhere as well.
+
+A "matcher" is simply an object with a `Matches` method defining a set of golang
+values matched by the matcher, and a `Description` method describing that set.
+For example, here are some matchers:
+
+```go
+// Numbers
+Equals(17.13)
+LessThan(19)
+
+// Strings
+Equals("taco")
+HasSubstr("burrito")
+MatchesRegex("t.*o")
+
+// Combining matchers
+AnyOf(LessThan(17), GreaterThan(19))
+```
+
+There are lots more; see [here][reference] for a reference. You can also add
+your own simply by implementing the `oglematchers.Matcher` interface.
+
+
+Installation
+------------
+
+First, make sure you have installed Go 1.0.2 or newer. See
+[here][golang-install] for instructions.
+
+Use the following command to install `oglematchers` and keep it up to date:
+
+    go get -u github.com/smartystreets/assertions/internal/oglematchers
+
+
+Documentation
+-------------
+
+See [here][reference] for documentation. Alternatively, you can install the
+package and then use `godoc`:
+
+    godoc github.com/smartystreets/assertions/internal/oglematchers

+// Package oglematchers provides a set of matchers useful in a testing or
+// mocking framework. These matchers are inspired by and mostly compatible with
+// Google Test for C++ and Google JS Test.
+//
+// This package is used by github.com/smartystreets/assertions/internal/ogletest and
+// github.com/smartystreets/assertions/internal/oglemock, which may be more directly useful if you're not
+// writing your own testing package or defining your own matchers.
+package oglematchers
+
+// A Matcher is some predicate implicitly defining a set of values that it
+// matches. For example, GreaterThan(17) matches all numeric values greater
+// than 17, and HasSubstr("taco") matches all strings with the substring
+// "taco".
+//
+// Matchers are typically exposed to tests via constructor functions like
+// HasSubstr. In order to implement such a function you can either define your
+// own matcher type or use NewMatcher.
+type Matcher interface {
+	// Check whether the supplied value belongs to the the set defined by the
+	// matcher. Return a non-nil error if and only if it does not.
+	//
+	// The error describes why the value doesn't match. The error text is a
+	// relative clause that is suitable for being placed after the value. For
+	// example, a predicate that matches strings with a particular substring may,
+	// when presented with a numerical value, return the following error text:
+	//
+	//     "which is not a string"
+	//
+	// Then the failure message may look like:
+	//
+	//     Expected: has substring "taco"
+	//     Actual:   17, which is not a string
+	//
+	// If the error is self-apparent based on the description of the matcher, the
+	// error text may be empty (but the error still non-nil). For example:
+	//
+	//     Expected: 17
+	//     Actual:   19
+	//
+	// If you are implementing a new matcher, see also the documentation on
+	// FatalError.
+	Matches(candidate interface{}) error
+
+	// Description returns a string describing the property that values matching
+	// this matcher have, as a verb phrase where the subject is the value. For
+	// example, "is greather than 17" or "has substring "taco"".
+	Description() string
+}
+
+// FatalError is an implementation of the error interface that may be returned
+// from matchers, indicating the error should be propagated. Returning a
+// *FatalError indicates that the matcher doesn't process values of the
+// supplied type, or otherwise doesn't know how to handle the value.
+//
+// For example, if GreaterThan(17) returned false for the value "taco" without
+// a fatal error, then Not(GreaterThan(17)) would return true. This is
+// technically correct, but is surprising and may mask failures where the wrong
+// sort of matcher is accidentally used. Instead, GreaterThan(17) can return a
+// fatal error, which will be propagated by Not().
+type FatalError struct {
+	errorText string
