// Package digest provides a generalized type to opaquely represent message
// digests and their operations within the registry. The Digest type is
// designed to serve as a flexible identifier in a content-addressable system.
// More importantly, it provides tools and wrappers to work with
// hash.Hash-based digests with little effort.
//
// Basics
//
// The format of a digest is simply a string with two parts, dubbed the
// "algorithm" and the "digest", separated by a colon:
//
// <algorithm>:<digest>
//
// An example of a sha256 digest representation follows:
//
// sha256:7173b809ca12ec5dee4506cd86be934c4596dd234ee82c0662eac04a8c2c71dc
//
// In this case, the string "sha256" is the algorithm and the hex bytes are
// the "digest".
//
// Because the Digest type is simply a string, once a valid Digest is
// obtained, comparisons are cheap, quick and simple to express with the
// standard equality operator.
//
// Verification
//
// The main benefit of using the Digest type is simple verification against a
// given digest. The Verifier interface, modeled after the stdlib hash.Hash
// interface, provides a common write sink for digest verification. After
// writing is complete, calling the Verifier.Verified method will indicate
// whether or not the stream of bytes matches the target digest.
//
// Missing Features
//
// In addition to the above, we intend to add the following features to this
// package:
//
// 1. A Digester type that supports write sink digest calculation.
//
// 2. Suspend and resume of ongoing digest calculations to support efficient digest verification in the registry.

/*
Package restful, a lean package for creating REST-style WebServices without magic.
WebServices and Routes
A WebService has a collection of Route objects that dispatch incoming Http Requests to a function calls.
Typically, a WebService has a root path (e.g. /users) and defines common MIME types for its routes.
WebServices must be added to a container (see below) in order to handler Http requests from a server.
A Route is defined by a HTTP method, an URL path and (optionally) the MIME types it consumes (Content-Type) and produces (Accept).
This package has the logic to find the best matching Route and if found, call its Function.
ws := new(restful.WebService)
ws.
Path("/users").
Consumes(restful.MIME_JSON, restful.MIME_XML).
Produces(restful.MIME_JSON, restful.MIME_XML)
ws.Route(ws.GET("/{user-id}").To(u.findUser)) // u is a UserResource
...
// GET http://localhost:8080/users/1
func (u UserResource) findUser(request *restful.Request, response *restful.Response) {
id := request.PathParameter("user-id")
...
}
The (*Request, *Response) arguments provide functions for reading information from the request and writing information back to the response.
See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-user-resource.go with a full implementation.
Regular expression matching Routes
A Route parameter can be specified using the format "uri/{var[:regexp]}" or the special version "uri/{var:*}" for matching the tail of the path.
For example, /persons/{name:[A-Z][A-Z]} can be used to restrict values for the parameter "name" to only contain capital alphabetic characters.
Regular expressions must use the standard Go syntax as described in the regexp package. (https://code.google.com/p/re2/wiki/Syntax)
This feature requires the use of a CurlyRouter.
Containers
A Container holds a collection of WebServices, Filters and a http.ServeMux for multiplexing http requests.
Using the statements "restful.Add(...) and restful.Filter(...)" will register WebServices and Filters to the Default Container.
The Default container of go-restful uses the http.DefaultServeMux.
You can create your own Container and create a new http.Server for that particular container.
container := restful.NewContainer()
server := &http.Server{Addr: ":8081", Handler: container}
Filters
A filter dynamically intercepts requests and responses to transform or use the information contained in the requests or responses.
You can use filters to perform generic logging, measurement, authentication, redirect, set response headers etc.
In the restful package there are three hooks into the request,response flow where filters can be added.
Each filter must define a FilterFunction:
func (req *restful.Request, resp *restful.Response, chain *restful.FilterChain)
Use the following statement to pass the request,response pair to the next filter or RouteFunction
chain.ProcessFilter(req, resp)
Container Filters
These are processed before any registered WebService.
// install a (global) filter for the default container (processed before any webservice)
restful.Filter(globalLogging)
WebService Filters
These are processed before any Route of a WebService.
// install a webservice filter (processed before any route)
ws.Filter(webserviceLogging).Filter(measureTime)
Route Filters
These are processed before calling the function associated with the Route.
// install 2 chained route filters (processed before calling findUser)
ws.Route(ws.GET("/{user-id}").Filter(routeLogging).Filter(NewCountFilter().routeCounter).To(findUser))
See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-filters.go with full implementations.
Response Encoding
Two encodings are supported: gzip and deflate. To enable this for all responses:
restful.DefaultContainer.EnableContentEncoding(true)
If a Http request includes the Accept-Encoding header then the response content will be compressed using the specified encoding.
Alternatively, you can create a Filter that performs the encoding and install it per WebService or Route.
See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-encoding-filter.go
OPTIONS support
By installing a pre-defined container filter, your Webservice(s) can respond to the OPTIONS Http request.
Filter(OPTIONSFilter())
CORS
By installing the filter of a CrossOriginResourceSharing (CORS), your WebService(s) can handle CORS requests.
cors := CrossOriginResourceSharing{ExposeHeaders: []string{"X-My-Header"}, CookiesAllowed: false, Container: DefaultContainer}
Filter(cors.Filter)
Error Handling
Unexpected things happen. If a request cannot be processed because of a failure, your service needs to tell via the response what happened and why.
For this reason HTTP status codes exist and it is important to use the correct code in every exceptional situation.
400: Bad Request
If path or query parameters are not valid (content or type) then use http.StatusBadRequest.
404: Not Found
Despite a valid URI, the resource requested may not be available
500: Internal Server Error
If the application logic could not process the request (or write the response) then use http.StatusInternalServerError.
405: Method Not Allowed
The request has a valid URL but the method (GET,PUT,POST,...) is not allowed.
406: Not Acceptable
The request does not have or has an unknown Accept Header set for this operation.
415: Unsupported Media Type
The request does not have or has an unknown Content-Type Header set for this operation.
ServiceError
In addition to setting the correct (error) Http status code, you can choose to write a ServiceError message on the response.
Performance options
This package has several options that affect the performance of your service. It is important to understand them and how you can change it.
restful.DefaultContainer.Router(CurlyRouter{})
The default router is the RouterJSR311 which is an implementation of its spec (http://jsr311.java.net/nonav/releases/1.1/spec/spec.html).
However, it uses regular expressions for all its routes which, depending on your usecase, may consume a significant amount of time.
The CurlyRouter implementation is more lightweight that also allows you to use wildcards and expressions, but only if needed.
restful.DefaultContainer.DoNotRecover(true)
DoNotRecover controls whether panics will be caught to return HTTP 500.
If set to true, Route functions are responsible for handling any error situation.
Default value is false; it will recover from panics. This has performance implications.
restful.SetCacheReadEntity(false)
SetCacheReadEntity controls whether the response data ([]byte) is cached such that ReadEntity is repeatable.
If you expect to read large amounts of payload data, and you do not use this feature, you should set it to false.
restful.SetCompressorProvider(NewBoundedCachedCompressors(20, 20))
If content encoding is enabled then the default strategy for getting new gzip/zlib writers and readers is to use a sync.Pool.
Because writers are expensive structures, performance is even more improved when using a preloaded cache. You can also inject your own implementation.
Trouble shooting
This package has the means to produce detail logging of the complete Http request matching process and filter invocation.
Enabling this feature requires you to set an implementation of restful.StdLogger (e.g. log.Logger) instance such as:
restful.TraceLogger(log.New(os.Stdout, "[restful] ", log.LstdFlags|log.Lshortfile))
Logging
The restful.SetLogger() method allows you to override the logger used by the package. By default restful
uses the standard library `log` package and logs to stdout. Different logging packages are supported as
long as they conform to `StdLogger` interface defined in the `log` sub-package, writing an adapter for your
preferred package is simple.

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at ivan+abuse@flanders.co.nz. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at ivan+abuse@flanders.co.nz. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.

Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.

for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at ivan+abuse@flanders.co.nz. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at [http://contributor-covenant.org/version/1/4][version]

// Parameter a unique parameter is defined by a combination of a [name](#parameterName) and [location](#parameterIn).
//
// There are five possible parameter types.
// * Path - Used together with [Path Templating](#pathTemplating), where the parameter value is actually part of the operation's URL. This does not include the host or base path of the API. For example, in `/items/{itemId}`, the path parameter is `itemId`.
// * Query - Parameters that are appended to the URL. For example, in `/items?id=###`, the query parameter is `id`.
// * Header - Custom headers that are expected as part of the request.
// * Body - The payload that's appended to the HTTP request. Since there can only be one payload, there can only be *one* body parameter. The name of the body parameter has no effect on the parameter itself and is used for documentation purposes only. Since Form parameters are also in the payload, body and form parameters cannot exist together for the same operation.
// * Form - Used to describe the payload of an HTTP request when either `application/x-www-form-urlencoded` or `multipart/form-data` are used as the content type of the request (in Swagger's definition, the [`consumes`](#operationConsumes) property of an operation). This is the only parameter type that can be used to send files, thus supporting the `file` type. Since form parameters are sent in the payload, they cannot be declared together with a body parameter for the same operation. Form parameters have a different format based on the content-type used (for further details, consult http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4):
// * `application/x-www-form-urlencoded` - Similar to the format of Query parameters but as a payload. For example, `foo=1&bar=swagger` - both `foo` and `bar` are form parameters. This is normally used for simple parameters that are being transferred.
// * `multipart/form-data` - each parameter takes a section in the payload with an internal header. For example, for the header `Content-Disposition: form-data; name="submit-name"` the name of the parameter is `submit-name`. This type of form parameters is more commonly used for file transfers.

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at ivan+abuse@flanders.co.nz. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at [http://contributor-covenant.org/version/1/4][version]

convey to a third party a Combined Work that links statically or dynamically
to this Library without providing any Minimal Corresponding Source or
Minimal Application Code as set out in 4d or providing the installation
information set out in section 4e, provided that you comply with the other
provisions of LGPL3 and provided that you meet, for the Application the
terms and conditions of the license(s) which apply to the Application.
Except as stated in this special exception, the provisions of LGPL3 will

may apply this exception to your version of this Library, but you are not
obliged to do so. If you do not wish to do so, delete this exception
statement from your version. This exception does not (and cannot) modify any
license terms which apply to the Application, with which you must still

GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.
"The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.
A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".
The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:
a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:
a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license
document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:
a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.
e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities,
conveyed under the terms of this License.
b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.
