+[![Build Status](https://img.shields.io/travis/davecgh/go-spew.svg)]
+(https://travis-ci.org/davecgh/go-spew) [![ISC License]
+(http://img.shields.io/badge/license-ISC-blue.svg)](http://copyfree.org) [![Coverage Status]
+(https://img.shields.io/coveralls/davecgh/go-spew.svg)]
+(https://coveralls.io/r/davecgh/go-spew?branch=master)
+
+
+Go-spew implements a deep pretty printer for Go data structures to aid in
+debugging.  A comprehensive suite of tests with 100% test coverage is provided
+to ensure proper functionality.  See `test_coverage.txt` for the gocov coverage
+report.  Go-spew is licensed under the liberal ISC license, so it may be used in
+open source or commercial projects.
+
+If you're interested in reading about how this package came to life and some
+of the challenges involved in providing a deep pretty printer, there is a blog
+post about it
+[here](https://web.archive.org/web/20160304013555/https://blog.cyphertite.com/go-spew-a-journey-into-dumping-go-data-structures/).
+
+## Documentation
+
+[![GoDoc](https://img.shields.io/badge/godoc-reference-blue.svg)]
+(http://godoc.org/github.com/davecgh/go-spew/spew)
+
+Full `go doc` style documentation for the project can be viewed online without
+installing this package by using the excellent GoDoc site here:
+http://godoc.org/github.com/davecgh/go-spew/spew
+
+You can also view the documentation locally once the package is installed with
+the `godoc` tool by running `godoc -http=":6060"` and pointing your browser to
+http://localhost:6060/pkg/github.com/davecgh/go-spew/spew
+
+## Installation
+
+```bash
+$ go get -u github.com/davecgh/go-spew/spew
+```
+
+## Quick Start
+
+Add this import line to the file you're working in:
+
+```Go
+import "github.com/davecgh/go-spew/spew"
+```
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+
+```Go
+spew.Dump(myVar1, myVar2, ...)
+spew.Fdump(someWriter, myVar1, myVar2, ...)
+str := spew.Sdump(myVar1, myVar2, ...)
+```
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with %v (most
+compact), %+v (adds pointer addresses), %#v (adds types), or %#+v (adds types
+and pointer addresses): 
+
+```Go
+spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+```
+
+## Debugging a Web Application Example
+
+Here is an example of how you can use `spew.Sdump()` to help debug a web application. Please be sure to wrap your output using the `html.EscapeString()` function for safety reasons. You should also only use this debugging technique in a development environment, never in production.
+
+```Go
+package main
+
+import (
+    "fmt"
+    "html"
+    "net/http"
+
+    "github.com/davecgh/go-spew/spew"
+)
+
+func handler(w http.ResponseWriter, r *http.Request) {
+    w.Header().Set("Content-Type", "text/html")
+    fmt.Fprintf(w, "Hi there, %s!", r.URL.Path[1:])
+    fmt.Fprintf(w, "<!--\n" + html.EscapeString(spew.Sdump(w)) + "\n-->")
+}
+
+func main() {
+    http.HandleFunc("/", handler)
+    http.ListenAndServe(":8080", nil)
+}
+```
+
+## Sample Dump Output
+
+```
+(main.Foo) {
+ unexportedField: (*main.Bar)(0xf84002e210)({
+  flag: (main.Flag) flagTwo,
+  data: (uintptr) <nil>
+ }),
+ ExportedField: (map[interface {}]interface {}) {
+  (string) "one": (bool) true
+ }
+}
+([]uint8) {
+ 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
+ 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
+ 00000020  31 32                                             |12|
+}
+```
+
+## Sample Formatter Output
+
+Double pointer to a uint8:
+```
+	  %v: <**>5
+	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
+	 %#v: (**uint8)5
+	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+```
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+```
+	  %v: <*>{1 <*><shown>}
+	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+```
+
+## Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type. For
+convenience, all of the top-level functions use a global state available via the
+spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions. This allows concurrent configuration
+options. See the ConfigState documentation for more details.
+
+```
+* Indent
+	String to use for each indentation level for Dump functions.
+	It is a single space by default.  A popular alternative is "\t".
+
+* MaxDepth
+	Maximum number of levels to descend into nested data structures.
+	There is no limit by default.
+
+* DisableMethods
+	Disables invocation of error and Stringer interface methods.
+	Method invocation is enabled by default.
+
+* DisablePointerMethods
+	Disables invocation of error and Stringer interface methods on types
+	which only accept pointer receivers from non-pointer variables.  This option
+	relies on access to the unsafe package, so it will not have any effect when
+	running in environments without access to the unsafe package such as Google
+	App Engine or with the "safe" build tag specified.
+	Pointer method invocation is enabled by default.
+
+* DisablePointerAddresses
+	DisablePointerAddresses specifies whether to disable the printing of
+	pointer addresses. This is useful when diffing data structures in tests.
+
+* DisableCapacities
+	DisableCapacities specifies whether to disable the printing of capacities
+	for arrays, slices, maps and channels. This is useful when diffing data
+	structures in tests.
+
+* ContinueOnMethod
+	Enables recursion into types after invoking error and Stringer interface
+	methods. Recursion after method invocation is disabled by default.
+
+* SortKeys
+	Specifies map keys should be sorted before being printed. Use
+	this to have a more deterministic, diffable output.  Note that
+	only native types (bool, int, uint, floats, uintptr and string)
+	and types which implement error or Stringer interfaces are supported,
+	with other types sorted according to the reflect.Value.String() output
+	which guarantees display stability.  Natural map order is used by
+	default.
+
+* SpewKeys
+	SpewKeys specifies that, as a last resort attempt, map keys should be
+	spewed to strings and sorted by those strings.  This is only considered
+	if SortKeys is true.
+
+```
+
+## Unsafe Package Dependency
+
+This package relies on the unsafe package to perform some of the more advanced
+features, however it also supports a "limited" mode which allows it to work in
+environments where the unsafe package is not available.  By default, it will
+operate in this mode on Google App Engine and when compiled with GopherJS.  The
+"safe" build tag may also be specified to force the package to build without
+using the unsafe package.

+# Contributing to beego
+
+beego is an open source project.
+
+It is the work of hundreds of contributors. We appreciate your help!
+
+Here are instructions to get you started. They are probably not perfect, 
+please let us know if anything feels wrong or incomplete.
+
+## Contribution guidelines
+
+### Pull requests
+
+First of all. beego follow the gitflow. So please send you pull request 
+to **develop** branch. We will close the pull request to master branch.
+
+We are always happy to receive pull requests, and do our best to
+review them as fast as possible. Not sure if that typo is worth a pull
+request? Do it! We will appreciate it.
+
+If your pull request is not accepted on the first try, don't be
+discouraged! Sometimes we can make a mistake, please do more explaining 
+for us. We will appreciate it.
+
+We're trying very hard to keep beego simple and fast. We don't want it
+to do everything for everybody. This means that we might decide against
+incorporating a new feature. But we will give you some advice on how to 
+do it in other way.
+
+### Create issues
+
+Any significant improvement should be documented as [a GitHub
+issue](https://github.com/astaxie/beego/issues) before anybody
+starts working on it. 
+
+Also when filing an issue, make sure to answer these five questions:
+
+- What version of beego are you using (bee version)?
+- What operating system and processor architecture are you using?
+- What did you do?
+- What did you expect to see?
+- What did you see instead?
+
+### but check existing issues and docs first!
+
+Please take a moment to check that an issue doesn't already exist
+documenting your bug report or improvement proposal. If it does, it
+never hurts to add a quick "+1" or "I have this problem too". This will
+help prioritize the most common problems and requests.
+
+Also if you don't know how to use it. please make sure you have read though
+the docs in http://beego.me/docs

+## cache
+cache is a Go cache manager. It can use many cache adapters. The repo is inspired by `database/sql` .
+
+
+## How to install?
+
+	go get github.com/astaxie/beego/cache
+
+
+## What adapters are supported?
+
+As of now this cache support memory, Memcache and Redis.
+
+
+## How to use it?
+
+First you must import it
+
+	import (
+		"github.com/astaxie/beego/cache"
+	)
+
+Then init a Cache (example with memory adapter)
+
+	bm, err := cache.NewCache("memory", `{"interval":60}`)	
+
+Use it like this:	
+	
+	bm.Put("astaxie", 1, 10 * time.Second)
+	bm.Get("astaxie")
+	bm.IsExist("astaxie")
+	bm.Delete("astaxie")
+
+
+## Memory adapter
+
+Configure memory adapter like this:
+
+	{"interval":60}
+
+interval means the gc time. The cache will check at each time interval, whether item has expired.
+
+
+## Memcache adapter
+
+Memcache adapter use the [gomemcache](http://github.com/bradfitz/gomemcache) client.
+
+Configure like this:
+
+	{"conn":"127.0.0.1:11211"}
+
+
+## Redis adapter
+
+Redis adapter use the [redigo](http://github.com/garyburd/redigo) client.
+
+Configure like this:
+
+	{"conn":":6039"}
