+Goroutine local storage
+
+### IMPORTANT NOTE ###
+
+It is my duty to point you to https://blog.golang.org/context, which is how 
+Google solves all of the problems you'd perhaps consider using this package
+for at scale. 
+
+One downside to Google's approach is that *all* of your functions must have
+a new first argument, but after clearing that hurdle everything else is much
+better.
+
+If you aren't interested in this warning, read on.
+
+### Huhwaht? Why? ###
+
+Every so often, a thread shows up on the
+[golang-nuts](https://groups.google.com/d/forum/golang-nuts) asking for some
+form of goroutine-local-storage, or some kind of goroutine id, or some kind of
+context. There are a few valid use cases for goroutine-local-storage, one of
+the most prominent being log line context. One poster was interested in being
+able to log an HTTP request context id in every log line in the same goroutine
+as the incoming HTTP request, without having to change every library and
+function call he was interested in logging.
+
+This would be pretty useful. Provided that you could get some kind of
+goroutine-local-storage, you could call
+[log.SetOutput](http://golang.org/pkg/log/#SetOutput) with your own logging
+writer that checks goroutine-local-storage for some context information and
+adds that context to your log lines.
+
+But alas, Andrew Gerrand's typically diplomatic answer to the question of
+goroutine-local variables was:
+
+> We wouldn't even be having this discussion if thread local storage wasn't
+> useful. But every feature comes at a cost, and in my opinion the cost of
+> threadlocals far outweighs their benefits. They're just not a good fit for
+> Go.
+
+So, yeah, that makes sense. That's a pretty good reason for why the language
+won't support a specific and (relatively) unuseful feature that requires some
+runtime changes, just for the sake of a little bit of log improvement.
+
+But does Go require runtime changes?
+
+### How it works ###
+
+Go has pretty fantastic introspective and reflective features, but one thing Go
+doesn't give you is any kind of access to the stack pointer, or frame pointer,
+or goroutine id, or anything contextual about your current stack. It gives you
+access to your list of callers, but only along with program counters, which are
+fixed at compile time.
+
+But it does give you the stack.
+
+So, we define 16 special functions and embed base-16 tags into the stack using
+the call order of those 16 functions. Then, we can read our tags back out of
+the stack looking at the callers list.
+
+We then use these tags as an index into a traditional map for implementing
+this library.
+
+### What are people saying? ###
+
+"Wow, that's horrifying."
+
+"This is the most terrible thing I have seen in a very long time."
+
+"Where is it getting a context from? Is this serializing all the requests? 
+What the heck is the client being bound to? What are these tags? Why does he 
+need callers? Oh god no. No no no."
+
+### Docs ###
+
+Please see the docs at http://godoc.org/github.com/jtolds/gls
+
+### Related ###
+
+If you're okay relying on the string format of the current runtime stacktrace 
+including a unique goroutine id (not guaranteed by the spec or anything, but 
+very unlikely to change within a Go release), you might be able to squeeze 
+out a bit more performance by using this similar library, inspired by some 
+code Brad Fitzpatrick wrote for debugging his HTTP/2 library: 
+https://github.com/tylerb/gls (in contrast, jtolds/gls doesn't require 
+any knowledge of the string format of the runtime stacktrace, which 
+probably adds unnecessary overhead).

+# Contributing
+
+In general, the code posted to the [SmartyStreets github organization](https://github.com/smartystreets) is created to solve specific problems at SmartyStreets that are ancillary to our core products in the address verification industry and may or may not be useful to other organizations or developers. Our reason for posting said code isn't necessarily to solicit feedback or contributions from the community but more as a showcase of some of the approaches to solving problems we have adopted.
+
+Having stated that, we do consider issues raised by other githubbers as well as contributions submitted via pull requests. When submitting such a pull request, please follow these guidelines:
+
+- _Look before you leap:_ If the changes you plan to make are significant, it's in everyone's best interest for you to discuss them with a SmartyStreets team member prior to opening a pull request.
+- _License and ownership:_ If modifying the `LICENSE.md` file, limit your changes to fixing typographical mistakes. Do NOT modify the actual terms in the license or the copyright by **SmartyStreets, LLC**. Code submitted to SmartyStreets projects becomes property of SmartyStreets and must be compatible with the associated license.
+- _Testing:_ If the code you are submitting resides in packages/modules covered by automated tests, be sure to add passing tests that cover your changes and assert expected behavior and state. Submit the additional test cases as part of your change set.
+- _Style:_ Match your approach to **naming** and **formatting** with the surrounding code. Basically, the code you submit shouldn't stand out.
+  - "Naming" refers to such constructs as variables, methods, functions, classes, structs, interfaces, packages, modules, directories, files, etc...
+  - "Formatting" refers to such constructs as whitespace, horizontal line length, vertical function length, vertical file length, indentation, curly braces, etc...

+# assertions
+--
+    import "github.com/smartystreets/assertions"
+
+Package assertions contains the implementations for all assertions which are
+referenced in goconvey's `convey` package
+(github.com/smartystreets/goconvey/convey) and gunit
+(github.com/smartystreets/gunit) for use with the So(...) method. They can also
+be used in traditional Go test functions and even in applications.
+
+Many of the assertions lean heavily on work done by Aaron Jacobs in his
+excellent oglematchers library. (https://github.com/jacobsa/oglematchers) The
+ShouldResemble assertion leans heavily on work done by Daniel Jacques in his
+very helpful go-render library. (https://github.com/luci/go-render)
+
+## Usage
+
+#### func  GoConveyMode
+
+```go
+func GoConveyMode(yes bool)
+```
+GoConveyMode provides control over JSON serialization of failures. When using
+the assertions in this package from the convey package JSON results are very
+helpful and can be rendered in a DIFF view. In that case, this function will be
+called with a true value to enable the JSON serialization. By default, the
+assertions in this package will not serializer a JSON result, making standalone
+ussage more convenient.
+
+#### func  ShouldAlmostEqual
+
+```go
+func ShouldAlmostEqual(actual interface{}, expected ...interface{}) string
+```

+even application logging. It allows you to perform assertion-like behavior (and
+get nicely formatted messages detailing discrepancies) but without the program
+blowing up or panicking. All that is required is to import this package and call
+`So` with one of the assertions exported by this package as the second
+parameter. The first return parameter is a boolean indicating if the assertion
+was true. The second return parameter is the well-formatted message showing why
+an assertion was incorrect, or blank if the assertion was correct.

+func (this *Assertion) So(actual interface{}, assert assertion, expected ...interface{}) bool
+```
+So calls the standalone So function and additionally, calls t.Error in failure
+scenarios.
+
+#### type FailureView
+
+```go
+type FailureView struct {
+	Message  string `json:"Message"`
+	Expected string `json:"Expected"`
+	Actual   string `json:"Actual"`
+}
+```
+
+This struct is also declared in
+github.com/smartystreets/goconvey/convey/reporting. The json struct tags should
+be equal in both declarations.
+
+#### type Serializer
+
+```go
+type Serializer interface {
+	// contains filtered or unexported methods
+}
+```

+
+`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

+// 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().

-## Supporting Go flags when using pflag
-In order to support flags defined using Go's `flag` package, they must be added to the `pflag` flagset. This is usually necessary
-to support flags defined by third-party dependencies (e.g. `golang/glog`).
-
-**Example**: You want to add the Go flags to the `CommandLine` flagset
-```go
-import (
-	goflag "flag"
-	flag "github.com/spf13/pflag"
-)
-
-var ip *int = flag.Int("flagname", 1234, "help message for flagname")
-
-func main() {
-	flag.CommandLine.AddGoFlagSet(goflag.CommandLine)
-	flag.Parse()
-}
