 					  EUROPEAN UNION PUBLIC LICENCE v. 1.2
 					  EUPL © the European Union 2007, 2016
 This European Union Public Licence (the ‘EUPL’) applies to the Work (as defined
 below) which is provided under the terms of this Licence. Any use of the Work,
 other than as authorised under this Licence is prohibited (to the extent such
 use is covered by a right of the copyright holder of the Work).
 The Work is provided under the terms of this Licence when the Licensor (as
 defined below) has placed the following notice immediately following the
 copyright notice for the Work:
 		Licensed under the EUPL
 or has expressed by any other means his willingness to license under the EUPL.
 1. Definitions
 In this Licence, the following terms have the following meaning:
 - ‘The Licence’: this Licence.
 - ‘The Original Work’: the work or software distributed or communicated by the
  Licensor under this Licence, available as Source Code and also as Executable
  Code as the case may be.
 - ‘Derivative Works’: the works or software that could be created by the
  Licensee, based upon the Original Work or modifications thereof. This Licence
  does not define the extent of modification or dependence on the Original Work
  required in order to classify a work as a Derivative Work; this extent is
  determined by copyright law applicable in the country mentioned in Article 15.
 - ‘The Work’: the Original Work or its Derivative Works.
 - ‘The Source Code’: the human-readable form of the Work which is the most
  convenient for people to study and modify.
 - ‘The Executable Code’: any code which has generally been compiled and which is
  meant to be interpreted by a computer as a program.
 - ‘The Licensor’: the natural or legal person that distributes or communicates
  the Work under the Licence.
 - ‘Contributor(s)’: any natural or legal person who modifies the Work under the
  Licence, or otherwise contributes to the creation of a Derivative Work.
 - ‘The Licensee’ or ‘You’: any natural or legal person who makes any usage of
  the Work under the terms of the Licence.
 - ‘Distribution’ or ‘Communication’: any act of selling, giving, lending,
  renting, distributing, communicating, transmitting, or otherwise making
  available, online or offline, copies of the Work or providing access to its
  essential functionalities at the disposal of any other natural or legal
  person.
 2. Scope of the rights granted by the Licence
 The Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
 sublicensable licence to do the following, for the duration of copyright vested
 in the Original Work:
 - use the Work in any circumstance and for all usage,
 - reproduce the Work,
 - modify the Work, and make Derivative Works based upon the Work,
 - communicate to the public, including the right to make available or display
  the Work or copies thereof to the public and perform publicly, as the case may
  be, the Work,
 - distribute the Work or copies thereof,
 - lend and rent the Work or copies thereof,
 - sublicense rights in the Work or copies thereof.
 Those rights can be exercised on any media, supports and formats, whether now
 known or later invented, as far as the applicable law permits so.
 In the countries where moral rights apply, the Licensor waives his right to
 exercise his moral right to the extent allowed by law in order to make effective
 the licence of the economic rights here above listed.
 The Licensor grants to the Licensee royalty-free, non-exclusive usage rights to
 any patents held by the Licensor, to the extent necessary to make use of the
 rights granted on the Work under this Licence.
 3. Communication of the Source Code
 The Licensor may provide the Work either in its Source Code form, or as
 Executable Code. If the Work is provided as Executable Code, the Licensor
 provides in addition a machine-readable copy of the Source Code of the Work
 along with each copy of the Work that the Licensor distributes or indicates, in
 a notice following the copyright notice attached to the Work, a repository where
 the Source Code is easily and freely accessible for as long as the Licensor
 continues to distribute or communicate the Work.
 4. Limitations on copyright
 Nothing in this Licence is intended to deprive the Licensee of the benefits from
 any exception or limitation to the exclusive rights of the rights owners in the
 Work, of the exhaustion of those rights or of other applicable limitations
 thereto.
 5. Obligations of the Licensee
 The grant of the rights mentioned above is subject to some restrictions and
 obligations imposed on the Licensee. Those obligations are the following:
 Attribution right: The Licensee shall keep intact all copyright, patent or
 trademarks notices and all notices that refer to the Licence and to the
 disclaimer of warranties. The Licensee must include a copy of such notices and a
 copy of the Licence with every copy of the Work he/she distributes or
 communicates. The Licensee must cause any Derivative Work to carry prominent
 notices stating that the Work has been modified and the date of modification.
 Copyleft clause: If the Licensee distributes or communicates copies of the
 Original Works or Derivative Works, this Distribution or Communication will be
 done under the terms of this Licence or of a later version of this Licence
 unless the Original Work is expressly distributed only under this version of the
 Licence — for example by communicating ‘EUPL v. 1.2 only’. The Licensee
 (becoming Licensor) cannot offer or impose any additional terms or conditions on
 the Work or Derivative Work that alter or restrict the terms of the Licence.
 Compatibility clause: If the Licensee Distributes or Communicates Derivative
 Works or copies thereof based upon both the Work and another work licensed under
 a Compatible Licence, this Distribution or Communication can be done under the
 terms of this Compatible Licence. For the sake of this clause, ‘Compatible
 Licence’ refers to the licences listed in the appendix attached to this Licence.
 Should the Licensee's obligations under the Compatible Licence conflict with
 his/her obligations under this Licence, the obligations of the Compatible
 Licence shall prevail.
 Provision of Source Code: When distributing or communicating copies of the Work,
 the Licensee will provide a machine-readable copy of the Source Code or indicate
 a repository where this Source will be easily and freely available for as long
 as the Licensee continues to distribute or communicate the Work.
 Legal Protection: This Licence does not grant permission to use the trade names,
 trademarks, service marks, or names of the Licensor, except as required for
 reasonable and customary use in describing the origin of the Work and
 reproducing the content of the copyright notice.
 6. Chain of Authorship
 The original Licensor warrants that the copyright in the Original Work granted
 hereunder is owned by him/her or licensed to him/her and that he/she has the
 power and authority to grant the Licence.
 Each Contributor warrants that the copyright in the modifications he/she brings
 to the Work are owned by him/her or licensed to him/her and that he/she has the
 power and authority to grant the Licence.
 Each time You accept the Licence, the original Licensor and subsequent
 Contributors grant You a licence to their contributions to the Work, under the
 terms of this Licence.
 7. Disclaimer of Warranty
 The Work is a work in progress, which is continuously improved by numerous
 Contributors. It is not a finished work and may therefore contain defects or
 ‘bugs’ inherent to this type of development.
 For the above reason, the Work is provided under the Licence on an ‘as is’ basis
 and without warranties of any kind concerning the Work, including without
 limitation merchantability, fitness for a particular purpose, absence of defects
 or errors, accuracy, non-infringement of intellectual property rights other than
 copyright as stated in Article 6 of this Licence.
 This disclaimer of warranty is an essential part of the Licence and a condition
 for the grant of any rights to the Work.
 8. Disclaimer of Liability
 Except in the cases of wilful misconduct or damages directly caused to natural
 persons, the Licensor will in no event be liable for any direct or indirect,
 material or moral, damages of any kind, arising out of the Licence or of the use
 of the Work, including without limitation, damages for loss of goodwill, work
 stoppage, computer failure or malfunction, loss of data or any commercial
 damage, even if the Licensor has been advised of the possibility of such damage.
 However, the Licensor will be liable under statutory product liability laws as
 far such laws apply to the Work.
 9. Additional agreements
 While distributing the Work, You may choose to conclude an additional agreement,
 defining obligations or services consistent with this Licence. However, if
 accepting obligations, You may act only on your own behalf and on your sole
 responsibility, not on behalf of the original Licensor or 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
 the fact You have accepted any warranty or additional liability.
 10. Acceptance of the Licence
 The provisions of this Licence can be accepted by clicking on an icon ‘I agree’
 placed under the bottom of a window displaying the text of this Licence or by
 affirming consent in any other similar way, in accordance with the rules of
 applicable law. Clicking on that icon indicates your clear and irrevocable
 acceptance of this Licence and all of its terms and conditions.
 Similarly, you irrevocably accept this Licence and all of its terms and
 conditions by exercising any rights granted to You by Article 2 of this Licence,
 such as the use of the Work, the creation by You of a Derivative Work or the
 Distribution or Communication by You of the Work or copies thereof.
 11. Information to the public
 In case of any Distribution or Communication of the Work by means of electronic
 communication by You (for example, by offering to download the Work from a
 remote location) the distribution channel or media (for example, a website) must
 at least provide to the public the information requested by the applicable law
 regarding the Licensor, the Licence and the way it may be accessible, concluded,
 stored and reproduced by the Licensee.
 12. Termination of the Licence
 The Licence and the rights granted hereunder will terminate automatically upon
 any breach by the Licensee of the terms of the Licence.
 Such a termination will not terminate the licences of any person who has
 received the Work from the Licensee under the Licence, provided such persons
 remain in full compliance with the Licence.
 13. Miscellaneous
 Without prejudice of Article 9 above, the Licence represents the complete
 agreement between the Parties as to the Work.
 If any provision of the Licence is invalid or unenforceable under applicable
 law, this will not affect the validity or enforceability of the Licence as a
 whole. Such provision will be construed or reformed so as necessary to make it
 valid and enforceable.
 The European Commission may publish other linguistic versions or new versions of
 this Licence or updated versions of the Appendix, so far this is required and
 reasonable, without reducing the scope of the rights granted by the Licence. New
 versions of the Licence will be published with a unique version number.
 All linguistic versions of this Licence, approved by the European Commission,
 have identical value. Parties can take advantage of the linguistic version of
 their choice.
 14. Jurisdiction
 Without prejudice to specific agreement between parties,
 - any litigation resulting from the interpretation of this License, arising
  between the European Union institutions, bodies, offices or agencies, as a
  Licensor, and any Licensee, will be subject to the jurisdiction of the Court
  of Justice of the European Union, as laid down in article 272 of the Treaty on
  the Functioning of the European Union,
 - any litigation arising between other parties and resulting from the
  interpretation of this License, will be subject to the exclusive jurisdiction
  of the competent court where the Licensor resides or conducts its primary
  business.
 15. Applicable Law
 Without prejudice to specific agreement between parties,
 - this Licence shall be governed by the law of the European Union Member State
  where the Licensor has his seat, resides or has his registered office,
 - this licence shall be governed by Belgian law if the Licensor has no seat,
  residence or registered office inside a European Union Member State.

 # SwiftLog OSLog
 A OSLog ([unified logging][unfied-logging]) [backend implementation][backend] for [SwiftLog (swift-log)][swift-log].
 It maps the `label` parameter of [SwiftLog (swift-log) to the `subsystem` and
 `category` parameter of `OSLog`. It even allows the use of the bundle
 identifier - if any  as a value for the `subsystem` parameter.

 [backend]: https://swiftpackageindex.com/apple/swift-log/1.10.1/documentation/logging
 [swift-log]: https://github.com/apple/swift-log
 ## Installation
 To use this library in your project, add it to the package dependencies:
 ```swift
 .package(url: "https://github.com/astzweig/swift-log-oslog", from: "1.0.0")
 ```
 and add it as a dependency on the specific target:
 ```swift
 .target(
 	name: "YourTarget",
 	dependencies: [
 		.product(name: "LoggingOSLog", package: "swift-log-oslog")
 	]
 )
 ```
 ### Basic Usage
 ```swift
 // Import the logging API and this backend implementation
 import Logging
 #if canImport(Darwin)
 import LoggingOSLog
 #endif
 // Later, in your application initialization code
 func init() {
 	// ...
 	#if canImport(Darwin)
 	LoggingSystem.bootstrap(LoggingOSLog.init)
 	#endif
 	// Start creating loggers
 	let loggers: [String: Logger] = [
 		"main": Logger(label: "com.example.yourapp.Main"),
 		"mail": Logger(label: "com.example.yourapp.Mail System"),

 # ``LoggingOSLog``
 An unified logging backend implementation for SwiftLog.
 ## Overview
 LoggingOSLog is a logging backend implementation for [SwiftLog][swift-log], that
 routes log messages to [OSLog][oslog], the
 [unified logging system][unified-logging] on Apple platforms. On macOS you can
 view the log messages using the Console app or the `log` cli tool.
 While SwiftLog is available on all Swift platforms though, the
 unified logging system of OSLog is only available on Apple platforms.
 Use this library to combine both worlds. Use SwiftLog in your codebase and use
 this library as the backend implementation when compiling for an Apple platform,
 i.e. using `#if canImport(Darwin)`.
 [unified-logging]: https://developer.apple.com/documentation/os/logging
 [oslog]: https://developer.apple.com/documentation/oslog
 [backend]: https://swiftpackageindex.com/apple/swift-log/1.10.1/documentation/logging
 [swift-log]: https://github.com/apple/swift-log
 ## Getting started
 Use this package if you're writing a cross-platform (for example, Linux and
 macOS) application or library and still want to take full advantage of the
 unified logging system on Apple platforms.
 ### Adding the Dependency
 Add the dependency to your Package.swift:
 ```swift
 .package(url: "https://github.com/astzweig/swift-log-oslog", from: "1.0.0")
 ```
 And to your target:
 ```swift
 .target(
 	name: "YourTarget",
 	dependencies: [
 		.product(name: "LoggingOSLog", package: "swift-log-oslog")
 	]
 )
 ```
 ### Basic Usage
 ```swift
 // Import the logging API and this backend implementation
 import Logging
 #if canImport(Darwin)
 import LoggingOSLog
 #endif
 // Later, in your application initialization code
 func init() {
 	// ...
 	#if canImport(Darwin)
 	LoggingSystem.bootstrap(LoggingOSLog.init)
 	#endif
 	// Start creating loggers
 	let loggers: [String: Logger] = [
 		"main": Logger(label: "com.example.yourapp.Main"),
 		"mail": Logger(label: "com.example.yourapp.Mail System"),
 	]
 }
 ```
 ## Relation to the unified logging system
 The [unified logging system][unified-logging] uses two parameters to allow for
 better filtering of log messages: [subsystem][subsystem] and
 [category][category]. [SwiftLog][swift-log] has only a label parameter, so this
 library maps a reverse domain style label to the subsystem and category
 parameters of the unified logging system. See
 ``/LoggingOSLog/LoggingOSLog/init(label:)`` for more information.
 ### What this library does not supply
 This library does not implement any of the interpolation privacy features of
 the unified logging system, i.e. there is no way to redact or align a meta
 information, like the `Logging` API would allow.
