+这一功能通过 `range:` 段落标记来实现，客户端会解析这个标记中的配置，将其拆分成多个 proxy，每一个 proxy 以数字为后缀命名。

-
-An implementation of [docopt](http://docopt.org/) in the
-[Go](http://golang.org/) programming language.
-
-**docopt** helps you create *beautiful* command-line interfaces easily:
-
-```go
-package main
-
-import (
-	"fmt"
-	"github.com/docopt/docopt-go"
-)
-
-func main() {
-	  usage := `Naval Fate.
-
-Usage:
-  naval_fate ship new <name>...
-  naval_fate ship <name> move <x> <y> [--speed=<kn>]
-  naval_fate ship shoot <x> <y>
-  naval_fate mine (set|remove) <x> <y> [--moored|--drifting]
-  naval_fate -h | --help
-  naval_fate --version
-
-Options:
-  -h --help     Show this screen.
-  --version     Show version.
-  --speed=<kn>  Speed in knots [default: 10].
-  --moored      Moored (anchored) mine.
-  --drifting    Drifting mine.`
-
-	  arguments, _ := docopt.Parse(usage, nil, true, "Naval Fate 2.0", false)
-	  fmt.Println(arguments)
-}
-```
-
-**docopt** parses command-line arguments based on a help message. Don't
-write parser code: a good help message already has all the necessary
-information in it.
-
-## Installation
-
-⚠ Use the alias “docopt-go”. To use docopt in your Go code:
-
-```go
-import "github.com/docopt/docopt-go"
-```
-
-To install docopt according to your `$GOPATH`:
-
-```console
-$ go get github.com/docopt/docopt-go
-```
-
-## API
-
-```go
-func Parse(doc string, argv []string, help bool, version string,
-    optionsFirst bool, exit ...bool) (map[string]interface{}, error)
-```
-Parse `argv` based on the command-line interface described in `doc`.
-
-Given a conventional command-line help message, docopt creates a parser and
-processes the arguments. See
-https://github.com/docopt/docopt#help-message-format for a description of the
-help message format. If `argv` is `nil`, `os.Args[1:]` is used.
-
-docopt returns a map of option names to the values parsed from `argv`, and an
-error or `nil`.
-
-More documentation for docopt is available at
-[GoDoc.org](https://godoc.org/github.com/docopt/docopt.go).
-
-## Testing
-
-All tests from the Python version are implemented and passing
-at [Travis CI](https://travis-ci.org/docopt/docopt.go). New
-language-agnostic tests have been added
-to [test_golang.docopt](test_golang.docopt).
-
-To run tests for docopt-go, use `go test`.

+     non-exclusive license:
+
+     a. under intellectual property rights (other than patent or trademark)
+        Licensable by such Contributor to use, reproduce, make available,
+        modify, display, perform, distribute, and otherwise exploit its
+        Contributions, either on an unmodified basis, with Modifications, or

+        Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+     The licenses granted in Section 2.1 with respect to any Contribution
+     become effective for each Contribution on the date the Contributor first
+     distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+     The licenses granted in this Section 2 are the only rights granted under
+     this License. No additional rights or licenses will be implied from the
+     distribution or licensing of Covered Software under this License.
+     Notwithstanding Section 2.1(b) above, no patent license is granted by a
+     Contributor:
+
+     a. for any code that a Contributor has removed from Covered Software; or
+
+     b. for infringements caused by: (i) Your and any other third party's
+        modifications of Covered Software, or (ii) the combination of its
+        Contributions with other software (except as part of its Contributor
+        Version); or
+
+     c. under Patent Claims infringed by Covered Software in the absence of
+        its Contributions.
+
+     This License does not grant any rights in the trademarks, service marks,
+     or logos of any Contributor (except as may be necessary to comply with
+     the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+     No Contributor makes additional grants as a result of Your choice to
+     distribute the Covered Software under a subsequent version of this
+     License (see Section 10.2) or under the terms of a Secondary License (if
+     permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+     Each Contributor represents that the Contributor believes its
+     Contributions are its original creation(s) or it has sufficient rights to
+     grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+     This License is not intended to limit any rights You have under
+     applicable copyright doctrines of fair use, fair dealing, or other
+     equivalents.
+
+2.7. Conditions
+
+     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+     Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+     All distribution of Covered Software in Source Code Form, including any
+     Modifications that You create or to which You contribute, must be under
+     the terms of this License. You must inform recipients that the Source
+     Code Form of the Covered Software is governed by the terms of this
+     License, and how they can obtain a copy of this License. You may not
+     attempt to alter or restrict the recipients' rights in the Source Code
+     Form.
+
+3.2. Distribution of Executable Form
+
+     If You distribute Covered Software in Executable Form then:
+
+     a. such Covered Software must also be made available in Source Code Form,
+        as described in Section 3.1, and You must inform recipients of the
+        Executable Form how they can obtain a copy of such Source Code Form by
+        reasonable means in a timely manner, at a charge no more than the cost
+        of distribution to the recipient; and
+
+     b. You may distribute such Executable Form under the terms of this
+        License, or sublicense it under different terms, provided that the
+        license for the Executable Form does not attempt to limit or alter the
+        recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+     You may create and distribute a Larger Work under terms of Your choice,
+     provided that You also comply with the requirements of this License for
+     the Covered Software. If the Larger Work is a combination of Covered
+     Software with a work governed by one or more Secondary Licenses, and the
+     Covered Software is not Incompatible With Secondary Licenses, this
+     License permits You to additionally distribute such Covered Software
+     under the terms of such Secondary License(s), so that the recipient of
+     the Larger Work may, at their option, further distribute the Covered
+     Software under the terms of either this License or such Secondary
+     License(s).
+
+3.4. Notices
+
+     You may not remove or alter the substance of any license notices
+     (including copyright notices, patent notices, disclaimers of warranty, or
+     limitations of liability) contained within the Source Code Form of the
+     Covered Software, except that You may alter any license notices to the
+     extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+     You may choose to offer, and to charge a fee for, warranty, support,
+     indemnity or liability obligations to one or more recipients of Covered
+     Software. However, You may do so only on Your own behalf, and not on
+     behalf of any Contributor. You must make it absolutely clear that any
+     such warranty, support, indemnity, or liability obligation is offered by
+     You alone, and You hereby agree to indemnify every Contributor for any
+     liability incurred by such Contributor as a result of warranty, support,
+     indemnity or liability terms You offer. You may include additional
+     disclaimers of warranty and limitations of liability specific to any
+     jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+   If it is impossible for You to comply with any of the terms of this License
+   with respect to some or all of the Covered Software due to statute,
+   judicial order, or regulation then You must: (a) comply with the terms of
+   this License to the maximum extent possible; and (b) describe the
+   limitations and the code they affect. Such description must be placed in a
+   text file included with all distributions of the Covered Software under
+   this License. Except to the extent prohibited by statute or regulation,
+   such description must be sufficiently detailed for a recipient of ordinary
+   skill to be able to understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+     fail to comply with any of its terms. However, if You become compliant,
+     then the rights granted under this License from a particular Contributor
+     are reinstated (a) provisionally, unless and until such Contributor
+     explicitly and finally terminates Your grants, and (b) on an ongoing
+     basis, if such Contributor fails to notify You of the non-compliance by
+     some reasonable means prior to 60 days after You have come back into
+     compliance. Moreover, Your grants from a particular Contributor are
+     reinstated on an ongoing basis if such Contributor notifies You of the
+     non-compliance by some reasonable means, this is the first time You have
+     received notice of non-compliance with this License from such
+     Contributor, and You become compliant prior to 30 days after Your receipt
+     of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+     infringement claim (excluding declaratory judgment actions,
+     counter-claims, and cross-claims) alleging that a Contributor Version
+     directly or indirectly infringes any patent, then the rights granted to
+     You by any and all Contributors for the Covered Software under Section
+     2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+     license agreements (excluding distributors and resellers) which have been
+     validly granted by You or Your distributors under this License prior to
+     termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+   Covered Software is provided under this License on an "as is" basis,
+   without warranty of any kind, either expressed, implied, or statutory,
+   including, without limitation, warranties that the Covered Software is free
+   of defects, merchantable, fit for a particular purpose or non-infringing.
+   The entire risk as to the quality and performance of the Covered Software
+   is with You. Should any Covered Software prove defective in any respect,
+   You (not any Contributor) assume the cost of any necessary servicing,
+   repair, or correction. This disclaimer of warranty constitutes an essential
+   part of this License. No use of  any Covered Software is authorized under
+   this License except under this disclaimer.
+
+7. Limitation of Liability
+
+   Under no circumstances and under no legal theory, whether tort (including
+   negligence), contract, or otherwise, shall any Contributor, or anyone who
+   distributes Covered Software as permitted above, be liable to You for any
+   direct, indirect, special, incidental, or consequential damages of any
+   character including, without limitation, damages for lost profits, loss of
+   goodwill, work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses, even if such party shall have been
+   informed of the possibility of such damages. This limitation of liability
+   shall not apply to liability for death or personal injury resulting from
+   such party's negligence to the extent applicable law prohibits such
+   limitation. Some jurisdictions do not allow the exclusion or limitation of
+   incidental or consequential damages, so this exclusion and limitation may
+   not apply to You.
+
+8. Litigation
+
+   Any litigation relating to this License may be brought only in the courts
+   of a jurisdiction where the defendant maintains its principal place of
+   business and such litigation shall be governed by laws of that
+   jurisdiction, without reference to its conflict-of-law provisions. Nothing
+   in this Section shall prevent a party's ability to bring cross-claims or
+   counter-claims.
+
+9. Miscellaneous
+
+   This License represents the complete agreement concerning the subject
+   matter hereof. If any provision of this License is held to be
+   unenforceable, such provision shall be reformed only to the extent
+   necessary to make it enforceable. Any law or regulation which provides that
+   the language of a contract shall be construed against the drafter shall not
+   be used to construe this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+      Mozilla Foundation is the license steward. Except as provided in Section
+      10.3, no one other than the license steward has the right to modify or
+      publish new versions of this License. Each version will be given a
+      distinguishing version number.
+
+10.2. Effect of New Versions
+
+      You may distribute the Covered Software under the terms of the version
+      of the License under which You originally received the Covered Software,
+      or under the terms of any subsequent version published by the license
+      steward.
+
+10.3. Modified Versions
+
+      If you create software not governed by this License, and you want to
+      create a new license for such software, you may create and use a
+      modified version of this License if you rename the license and remove
+      any references to the name of the license steward (except to note that

+# Yamux
+
+Yamux (Yet another Multiplexer) is a multiplexing library for Golang.
+It relies on an underlying connection to provide reliability
+and ordering, such as TCP or Unix domain sockets, and provides
+stream-oriented multiplexing. It is inspired by SPDY but is not
+interoperable with it.
+
+Yamux features include:
+
+* Bi-directional streams
+  * Streams can be opened by either client or server
+  * Useful for NAT traversal
+  * Server-side push support
+* Flow control
+  * Avoid starvation
+  * Back-pressure to prevent overwhelming a receiver
+* Keep Alives
+  * Enables persistent connections over a load balancer
+* Efficient
+  * Enables thousands of logical streams with low overhead
+
+## Documentation
+
+For complete documentation, see the associated [Godoc](http://godoc.org/github.com/hashicorp/yamux).
+
+## Specification
+
+The full specification for Yamux is provided in the `spec.md` file.
+It can be used as a guide to implementors of interoperable libraries.
+
+## Usage
+
+Using Yamux is remarkably simple:
+
+```go
+
+func client() {
+    // Get a TCP connection
+    conn, err := net.Dial(...)
+    if err != nil {
+        panic(err)
+    }
+
+    // Setup client side of yamux
+    session, err := yamux.Client(conn, nil)
+    if err != nil {
+        panic(err)
+    }
+
+    // Open a new stream
+    stream, err := session.Open()
+    if err != nil {
+        panic(err)
+    }
+
+    // Stream implements net.Conn
+    stream.Write([]byte("ping"))
+}
+
+func server() {
+    // Accept a TCP connection
+    conn, err := listener.Accept()
+    if err != nil {
+        panic(err)
+    }
+
+    // Setup server side of yamux
+    session, err := yamux.Server(conn, nil)
+    if err != nil {
+        panic(err)
+    }
+
+    // Accept a stream
+    stream, err := session.Accept()
+    if err != nil {
+        panic(err)
+    }
+
+    // Listen for a message
+    buf := make([]byte, 4)
+    stream.Read(buf)
+}
+
+```
