-XGB is the X Go Binding, which is a low-level API to communicate with the
-core X protocol and many of the X extensions. It is closely modeled after
-XCB and xpyb.
-
-It is thread safe and gets immediate improvement from parallelism when
-GOMAXPROCS > 1. (See the benchmarks in xproto/xproto_test.go for evidence.)
-
-Please see doc.go for more info.
-
-Note that unless you know you need XGB, you can probably make your life
-easier by using a slightly higher level library: xgbutil.
-
-Quick Usage
-===========
-go get github.com/BurntSushi/xgb
-go run go/path/src/github.com/BurntSushi/xgb/examples/create-window/main.go
-
-BurntSushi's Fork
-=================
-I've forked the XGB repository from Google Code due to inactivty upstream.
-
-Godoc documentation can be found here:
-http://godoc.burntsushi.net/pkg/github.com/BurntSushi/xgb/
-
-Much of the code has been rewritten in an effort to support thread safety
-and multiple extensions. Namely, go_client.py has been thrown away in favor
-of an xgbgen package.
-
-The biggest parts that *haven't* been rewritten by me are the connection and
-authentication handshakes. They're inherently messy, and there's really no
-reason to re-work them. The rest of XGB has been completely rewritten.
-
-I like to release my code under the WTFPL, but since I'm starting with someone
-else's work, I'm leaving the original license/contributor/author information
-in tact.
-
-I suppose I can legitimately release xgbgen under the WTFPL. To be fair, it is
-at least as complex as XGB itself. *sigh*
-
-What follows is the original README:
-
-XGB README
-==========
-XGB is the X protocol Go language Binding.
-
-It is the Go equivalent of XCB, the X protocol C-language Binding
-(http://xcb.freedesktop.org/).
-
-Unless otherwise noted, the XGB source files are distributed
-under the BSD-style license found in the LICENSE file.
-
-Contributions should follow the same procedure as for the Go project:

-Package XGB provides the X Go Binding, which is a low-level API to communicate
-with the core X protocol and many of the X extensions.
-
-It is *very* closely modeled on XCB, so that experience with XCB (or xpyb) is
-easily translatable to XGB. That is, it uses the same cookie/reply model
-and is thread safe. There are otherwise no major differences (in the API).
-
-Most uses of XGB typically fall under the realm of window manager and GUI kit
-development, but other applications (like pagers, panels, tilers, etc.) may
-also require XGB. Moreover, it is a near certainty that if you need to work
-with X, xgbutil will be of great use to you as well:
-https://github.com/BurntSushi/xgbutil
-
-Example
-
-This is an extremely terse example that demonstrates how to connect to X,
-create a window, listen to StructureNotify events and Key{Press,Release}
-events, map the window, and print out all events received. An example with
-accompanying documentation can be found in examples/create-window.
-
-	package main
-
-	import (
-		"fmt"
-		"github.com/BurntSushi/xgb"
-		"github.com/BurntSushi/xgb/xproto"
-	)
-
-	func main() {
-		X, err := xgb.NewConn()
-		if err != nil {
-			fmt.Println(err)
-			return
-		}
-
-		wid, _ := xproto.NewWindowId(X)
-		screen := xproto.Setup(X).DefaultScreen(X)
-		xproto.CreateWindow(X, screen.RootDepth, wid, screen.Root,
-			0, 0, 500, 500, 0,
-			xproto.WindowClassInputOutput, screen.RootVisual,
-			xproto.CwBackPixel | xproto.CwEventMask,
-			[]uint32{ // values must be in the order defined by the protocol
-				0xffffffff,
-				xproto.EventMaskStructureNotify |
-				xproto.EventMaskKeyPress |
-				xproto.EventMaskKeyRelease})
-
-		xproto.MapWindow(X, wid)
-		for {
-			ev, xerr := X.WaitForEvent()
-			if ev == nil && xerr == nil {
-				fmt.Println("Both event and error are nil. Exiting...")
-				return
-			}
-
-			if ev != nil {
-				fmt.Printf("Event: %s\n", ev)
-			}
-			if xerr != nil {
-				fmt.Printf("Error: %s\n", xerr)
-			}
-		}
-	}
-
-Xinerama Example
-
-This is another small example that shows how to query Xinerama for geometry
-information of each active head. Accompanying documentation for this example
-can be found in examples/xinerama.
-
-	package main
-
-	import (
-		"fmt"
-		"log"
-		"github.com/BurntSushi/xgb"
-		"github.com/BurntSushi/xgb/xinerama"
-	)
-
-	func main() {
-		X, err := xgb.NewConn()
-		if err != nil {
-			log.Fatal(err)
-		}
-
-		// Initialize the Xinerama extension.
-		// The appropriate 'Init' function must be run for *every*
-		// extension before any of its requests can be used.
-		err = xinerama.Init(X)
-		if err != nil {
-			log.Fatal(err)
-		}
-
-		reply, err := xinerama.QueryScreens(X).Reply()
-		if err != nil {
-			log.Fatal(err)
-		}
-
-		fmt.Printf("Number of heads: %d\n", reply.Number)
-		for i, screen := range reply.ScreenInfo {
-			fmt.Printf("%d :: X: %d, Y: %d, Width: %d, Height: %d\n",
-				i, screen.XOrg, screen.YOrg, screen.Width, screen.Height)
-		}
-	}
-
-Parallelism
-
-XGB can benefit greatly from parallelism due to its concurrent design. For
-evidence of this claim, please see the benchmarks in xproto/xproto_test.go.
-
-Tests
-
-xproto/xproto_test.go contains a number of contrived tests that stress
-particular corners of XGB that I presume could be problem areas. Namely:
-requests with no replies, requests with replies, checked errors, unchecked
-errors, sequence number wrapping, cookie buffer flushing (i.e., forcing a round
-trip every N requests made that don't have a reply), getting/setting properties
-and creating a window and listening to StructureNotify events.
-
-Code Generator
-
-Both XCB and xpyb use the same Python module (xcbgen) for a code generator. XGB
-(before this fork) used the same code generator as well, but in my attempt to
-add support for more extensions, I found the code generator extremely difficult
-to work with. Therefore, I re-wrote the code generator in Go. It can be found
-in its own sub-package, xgbgen, of xgb. My design of xgbgen includes a rough
-consideration that it could be used for other languages.
-
-What works
-
-I am reasonably confident that the core X protocol is in full working form. I've
-also tested the Xinerama and RandR extensions sparingly. Many of the other
-existing extensions have Go source generated (and are compilable) and are
-included in this package, but I am currently unsure of their status. They
-*should* work.
-
-What does not work
-
-XKB is the only extension that intentionally does not work, although I suspect
-that GLX also does not work (however, there is Go source code for GLX that
-compiles, unlike XKB). I don't currently have any intention of getting XKB
-working, due to its complexity and my current mental incapacity to test it.

-	// 00111000 & 11001000 = 00001000.

-	Tests for XGB.
-
-	These tests only test the core X protocol at the moment. It isn't even
-	close to complete coverage (and probably never will be), but it does test
-	a number of different corners: requests with no replies, requests without
-	replies, checked (i.e., synchronous) errors, unchecked (i.e., asynchronous)
-	errors, and sequence number wrapping.
-
-	There are also a couple of benchmarks that show the difference between
-	correctly issuing lots of requests and gathering replies and
-	incorrectly doing the same. (This particular difference is one of the
-	claimed advantages of the XCB, and therefore XGB, family.)
-
-	In sum, these tests are more focused on testing the core xgb package itself,
-	rather than whether xproto has properly implemented the core X client
-	protocol.
