+
+Package imaging provides basic image processing functions (resize, rotate, crop, brightness/contrast adjustments, etc.).
+
+All the image processing functions provided by the package accept any image type that implements `image.Image` interface
+as an input, and return a new image of `*image.NRGBA` type (32bit RGBA colors, non-premultiplied alpha).
+
+## Installation
+
+    go get -u github.com/disintegration/imaging
+
+## Documentation
+
+http://godoc.org/github.com/disintegration/imaging
+
+## Usage examples
+
+A few usage examples can be found below. See the documentation for the full list of supported functions.
+
+### Image resizing
+
+```go
+// Resize srcImage to size = 128x128px using the Lanczos filter.
+dstImage128 := imaging.Resize(srcImage, 128, 128, imaging.Lanczos)
+
+// Resize srcImage to width = 800px preserving the aspect ratio.
+dstImage800 := imaging.Resize(srcImage, 800, 0, imaging.Lanczos)
+
+// Scale down srcImage to fit the 800x600px bounding box.
+dstImageFit := imaging.Fit(srcImage, 800, 600, imaging.Lanczos)
+
+// Resize and crop the srcImage to fill the 100x100px area.
+dstImageFill := imaging.Fill(srcImage, 100, 100, imaging.Center, imaging.Lanczos)
+```
+
+Imaging supports image resizing using various resampling filters. The most notable ones:
+- `Lanczos` - A high-quality resampling filter for photographic images yielding sharp results.
+- `CatmullRom` - A sharp cubic filter that is faster than Lanczos filter while providing similar results.
+- `MitchellNetravali` - A cubic filter that produces smoother results with less ringing artifacts than CatmullRom.
+- `Linear` - Bilinear resampling filter, produces smooth output. Faster than cubic filters.
+- `Box` - Simple and fast averaging filter appropriate for downscaling. When upscaling it's similar to NearestNeighbor.
+- `NearestNeighbor` - Fastest resampling filter, no antialiasing.
+
+The full list of supported filters:  NearestNeighbor, Box, Linear, Hermite, MitchellNetravali, CatmullRom, BSpline, Gaussian, Lanczos, Hann, Hamming, Blackman, Bartlett, Welch, Cosine. Custom filters can be created using ResampleFilter struct.

+
+### Gaussian Blur
+
+```go
+dstImage := imaging.Blur(srcImage, 0.5)
+```
+
+Sigma parameter allows to control the strength of the blurring effect.
+
+Original image                     | Sigma = 0.5                            | Sigma = 1.5

+
+### Sharpening
+
+```go
+dstImage := imaging.Sharpen(srcImage, 0.5)
+```
+
+`Sharpen` uses gaussian function internally. Sigma parameter allows to control the strength of the sharpening effect.
+
+Original image                     | Sigma = 0.5                               | Sigma = 1.5

+
+### Gamma correction
+
+```go
+dstImage := imaging.AdjustGamma(srcImage, 0.75)
+```
+
+Original image                     | Gamma = 0.75                             | Gamma = 1.25

+![srcImage](testdata/flowers_small.png) | ![dstImage](testdata/out_gamma_0.75.png) | ![dstImage](testdata/out_gamma_1.25.png)
+
+### Contrast adjustment
+
+```go
+dstImage := imaging.AdjustContrast(srcImage, 20)
+```
+
+Original image                     | Contrast = 15                              | Contrast = -15
+-----------------------------------|--------------------------------------------|-------------------------------------------
+![srcImage](testdata/flowers_small.png) | ![dstImage](testdata/out_contrast_p15.png) | ![dstImage](testdata/out_contrast_m15.png)
+
+### Brightness adjustment
+
+```go
+dstImage := imaging.AdjustBrightness(srcImage, 20)
+```
+
+Original image                     | Brightness = 10                              | Brightness = -10

+![srcImage](testdata/flowers_small.png) | ![dstImage](testdata/out_brightness_p10.png) | ![dstImage](testdata/out_brightness_m10.png)
+
+### Saturation adjustment
+
+```go
+dstImage := imaging.AdjustSaturation(srcImage, 20)
+```
+
+Original image                     | Saturation = 30                              | Saturation = -30

+## FAQ
+
+### Incorrect image orientation after processing (e.g. an image appears rotated after resizing)
+
+Most probably, the given image contains the EXIF orientation tag.
+The stadard `image/*` packages do not support loading and saving
+this kind of information. To fix the issue, try opening images with
+the `AutoOrientation` decode option. If this option is set to `true`,
+the image orientation is changed after decoding, according to the
+orientation tag (if present). Here's the example:
+
+```go
+img, err := imaging.Open("test.jpg", imaging.AutoOrientation(true))
+```
+
+### What's the difference between `imaging` and `gift` packages?
+
+[imaging](https://github.com/disintegration/imaging)
+is designed to be a lightweight and simple image manipulation package.
+It provides basic image processing functions and a few helper functions
+such as `Open` and `Save`. It consistently returns *image.NRGBA image 
+type (8 bits per channel, RGBA).
+
+[gift](https://github.com/disintegration/gift)
+supports more advanced image processing, for example, sRGB/Linear color
+space conversions. It also supports different output image types
+(e.g. 16 bits per channel) and provides easy-to-use API for chaining
+multiple processing steps together.
+
+## Example code
+
+```go
+package main
+
+import (
+	"image"
+	"image/color"
+	"log"
+
+	"github.com/disintegration/imaging"
+)
+
+func main() {
+	// Open a test image.
+	src, err := imaging.Open("testdata/flowers.png")
+	if err != nil {
+		log.Fatalf("failed to open image: %v", err)
+	}
+
+	// Crop the original image to 300x300px size using the center anchor.
+	src = imaging.CropAnchor(src, 300, 300, imaging.Center)
+
+	// Resize the cropped image to width = 200px preserving the aspect ratio.
+	src = imaging.Resize(src, 200, 0, imaging.Lanczos)
+
+	// Create a blurred version of the image.
+	img1 := imaging.Blur(src, 5)
+
+	// Create a grayscale version of the image with higher contrast and sharpness.
+	img2 := imaging.Grayscale(src)
+	img2 = imaging.AdjustContrast(img2, 20)
+	img2 = imaging.Sharpen(img2, 2)
+
+	// Create an inverted version of the image.
+	img3 := imaging.Invert(src)
+
+	// Create an embossed version of the image using a convolution filter.
+	img4 := imaging.Convolve3x3(
+		src,
+		[9]float64{
+			-1, -1, 0,
+			-1, 1, 1,
+			0, 1, 1,
+		},
+		nil,
+	)
+
+	// Create a new image and paste the four produced images into it.
+	dst := imaging.New(400, 400, color.NRGBA{0, 0, 0, 0})
+	dst = imaging.Paste(dst, img1, image.Pt(0, 0))
+	dst = imaging.Paste(dst, img2, image.Pt(0, 200))
+	dst = imaging.Paste(dst, img3, image.Pt(200, 0))
+	dst = imaging.Paste(dst, img4, image.Pt(200, 200))
+
+	// Save the resulting image as JPEG.
+	err = imaging.Save(dst, "testdata/out_example.jpg")
+	if err != nil {
+		log.Fatalf("failed to save image: %v", err)
+	}
+}

+  b) in the case of each subsequent Contributor:
+     i) changes to the Program, and
+     ii) additions to the Program;
+  where such changes and/or additions to the Program originate from
+  and are Distributed by that particular Contributor. A Contribution
+  "originates" from a Contributor if it was added to the Program by
+  such Contributor itself or anyone acting on such Contributor's behalf.
+  Contributions do not include changes or additions to the Program that
+  are not Modified Works.

+"Contributor" means any person or entity that Distributes the Program.
+
+"Licensed Patents" mean patent claims licensable by a Contributor which
+are necessarily infringed by the use or sale of its Contribution alone
+or when combined with the Program.
+
+"Program" means the Contributions Distributed in accordance with this
+Agreement.
+
+"Recipient" means anyone who receives the Program under this Agreement
+or any Secondary License (as applicable), including Contributors.
+
+"Derivative Works" shall mean any work, whether in Source Code or other
+form, that is based on (or derived from) the Program and for which the
+editorial revisions, annotations, elaborations, or other modifications
+represent, as a whole, an original work of authorship.
+
+"Modified Works" shall mean any work in Source Code or other form that
+results from an addition to, deletion from, or modification of the
+contents of the Program, including, for purposes of clarity any new file
+in Source Code form that contains any contents of the Program. Modified
+Works shall not include works that contain only declarations,
+interfaces, types, classes, structures, or files of the Program solely
+in each case in order to link to, bind by name, or subclass the Program
+or Modified Works thereof.
+
+"Distribute" means the acts of a) distributing or b) making available
+in any manner that enables the transfer of a copy.
+
+"Source Code" means the form of a Program preferred for making
+modifications, including but not limited to software source code,
+documentation source, and configuration files.
+
+"Secondary License" means either the GNU General Public License,

+exceptions or additional permissions as identified by the initial
+Contributor.
+
+2. GRANT OF RIGHTS
+
+  a) Subject to the terms of this Agreement, each Contributor hereby
+  grants Recipient a non-exclusive, worldwide, royalty-free copyright
+  license to reproduce, prepare Derivative Works of, publicly display,
+  publicly perform, Distribute and sublicense the Contribution of such
+  Contributor, if any, and such Derivative Works.
+
+  b) Subject to the terms of this Agreement, each Contributor hereby
+  grants Recipient a non-exclusive, worldwide, royalty-free patent
+  license under Licensed Patents to make, use, sell, offer to sell,
+  import and otherwise transfer the Contribution of such Contributor,
+  if any, in Source Code or other form. This patent license shall
+  apply to the combination of the Contribution and the Program if, at
+  the time the Contribution is added by the Contributor, such addition
+  of the Contribution causes such combination to be covered by the
+  Licensed Patents. The patent license shall not apply to any other
+  combinations which include the Contribution. No hardware per se is
+  licensed hereunder.
+
+  c) Recipient understands that although each Contributor grants the
+  licenses to its Contributions set forth herein, no assurances are
+  provided by any Contributor that the Program does not infringe the
+  patent or other intellectual property rights of any other entity.
+  Each Contributor disclaims any liability to Recipient for claims
+  brought by any other entity based on infringement of intellectual
+  property rights or otherwise. As a condition to exercising the
+  rights and licenses granted hereunder, each Recipient hereby
+  assumes sole responsibility to secure any other intellectual
+  property rights needed, if any. For example, if a third party
+  patent license is required to allow Recipient to Distribute the
+  Program, it is Recipient's responsibility to acquire that license
+  before distributing the Program.
+
+  d) Each Contributor represents that to its knowledge it has
+  sufficient copyright rights in its Contribution, if any, to grant
+  the copyright license set forth in this Agreement.
+
+  e) Notwithstanding the terms of any Secondary License, no
+  Contributor makes additional grants to any Recipient (other than
+  those set forth in this Agreement) as a result of such Recipient's
+  receipt of the Program under the terms of a Secondary License
+  (if permitted under the terms of Section 3).
+
+3. REQUIREMENTS
+
+3.1 If a Contributor Distributes the Program in any form, then:
+
+  a) the Program must also be made available as Source Code, in
+  accordance with section 3.2, and the Contributor must accompany
+  the Program with a statement that the Source Code for the Program
+  is available under this Agreement, and informs Recipients how to
+  obtain it in a reasonable manner on or through a medium customarily
+  used for software exchange; and
+
+  b) the Contributor may Distribute the Program under a license
+  different than this Agreement, provided that such license:
+     i) effectively disclaims on behalf of all other Contributors all
+     warranties and conditions, express and implied, including
+     warranties or conditions of title and non-infringement, and
+     implied warranties or conditions of merchantability and fitness
+     for a particular purpose;
+
+     ii) effectively excludes on behalf of all other Contributors all
+     liability for damages, including direct, indirect, special,
+     incidental and consequential damages, such as lost profits;
+
+     iii) does not attempt to limit or alter the recipients' rights
+     in the Source Code under section 3.2; and
+
+     iv) requires any subsequent distribution of the Program by any
+     party to be under a license that satisfies the requirements
+     of this section 3.
+
+3.2 When the Program is Distributed as Source Code:
+
+  a) it must be made available under this Agreement, or if the
+  Program (i) is combined with other material in a separate file or
+  files made available under a Secondary License, and (ii) the initial
+  Contributor attached to the Source Code the notice described in
+  Exhibit A of this Agreement, then the Program may be made available
+  under the terms of such Secondary Licenses, and
+
+  b) a copy of this Agreement must be included with each copy of
+  the Program.
+
+3.3 Contributors may not remove or alter any copyright, patent,
+trademark, attribution notices, disclaimers of warranty, or limitations
+of liability ("notices") contained within the Program from any copy of
+the Program which they Distribute, provided that Contributors may add
+their own appropriate notices.
+
+4. COMMERCIAL DISTRIBUTION
+
+Commercial distributors of software may accept certain responsibilities
+with respect to end users, business partners and the like. While this
+license is intended to facilitate the commercial use of the Program,
+the Contributor who includes the Program in a commercial product
+offering should do so in a manner which does not create potential
+liability for other Contributors. Therefore, if a Contributor includes
+the Program in a commercial product offering, such Contributor
+("Commercial Contributor") hereby agrees to defend and indemnify every
+other Contributor ("Indemnified Contributor") against any losses,
+damages and costs (collectively "Losses") arising from claims, lawsuits
+and other legal actions brought by a third party against the Indemnified
+Contributor to the extent caused by the acts or omissions of such
+Commercial Contributor in connection with its distribution of the Program
+in a commercial product offering. The obligations in this section do not
+apply to any claims or Losses relating to any actual or alleged
+intellectual property infringement. In order to qualify, an Indemnified
+Contributor must: a) promptly notify the Commercial Contributor in
+writing of such claim, and b) allow the Commercial Contributor to control,
+and cooperate with the Commercial Contributor in, the defense and any
+related settlement negotiations. The Indemnified Contributor may
+participate in any such claim at its own expense.
+
+For example, a Contributor might include the Program in a commercial
+product offering, Product X. That Contributor is then a Commercial
+Contributor. If that Commercial Contributor then makes performance
+claims, or offers warranties related to Product X, those performance
+claims and warranties are such Commercial Contributor's responsibility
+alone. Under this section, the Commercial Contributor would have to
+defend claims against the other Contributors related to those performance
+claims and warranties, and if a court requires any other Contributor to
+pay any damages as a result, the Commercial Contributor must pay
+those damages.
+
+5. NO WARRANTY
+
+EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
+PERMITTED BY APPLICABLE LAW, THE PROGRAM IS PROVIDED ON AN "AS IS"
+BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR
+IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF
+TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR
+PURPOSE. Each Recipient is solely responsible for determining the
+appropriateness of using and distributing the Program and assumes all
+risks associated with its exercise of rights under this Agreement,
+including but not limited to the risks and costs of program errors,
+compliance with applicable laws, damage to or loss of data, programs
+or equipment, and unavailability or interruption of operations.
+
+6. DISCLAIMER OF LIABILITY
+
+EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
+PERMITTED BY APPLICABLE LAW, NEITHER RECIPIENT NOR ANY CONTRIBUTORS
+SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
+EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST
+PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN
+CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE)
+ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE
+EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+7. GENERAL
+
+If any provision of this Agreement is invalid or unenforceable under
+applicable law, it shall not affect the validity or enforceability of
+the remainder of the terms of this Agreement, and without further
+action by the parties hereto, such provision shall be reformed to the
+minimum extent necessary to make such provision valid and enforceable.
+
+If Recipient institutes patent litigation against any entity
+(including a cross-claim or counterclaim in a lawsuit) alleging that the
+Program itself (excluding combinations of the Program with other software
+or hardware) infringes such Recipient's patent(s), then such Recipient's
+rights granted under Section 2(b) shall terminate as of the date such
+litigation is filed.
+
+All Recipient's rights under this Agreement shall terminate if it
+fails to comply with any of the material terms or conditions of this
+Agreement and does not cure such failure in a reasonable period of
+time after becoming aware of such noncompliance. If all Recipient's
+rights under this Agreement terminate, Recipient agrees to cease use
+and distribution of the Program as soon as reasonably practicable.
+However, Recipient's obligations under this Agreement and any licenses
+granted by Recipient relating to the Program shall continue and survive.
+
+Everyone is permitted to copy and distribute copies of this Agreement,
+but in order to avoid inconsistency the Agreement is copyrighted and
+may only be modified in the following manner. The Agreement Steward
+reserves the right to publish new versions (including revisions) of
+this Agreement from time to time. No one other than the Agreement
+Steward has the right to modify this Agreement. The Eclipse Foundation
+is the initial Agreement Steward. The Eclipse Foundation may assign the
+responsibility to serve as the Agreement Steward to a suitable separate
+entity. Each new version of the Agreement will be given a distinguishing
+version number. The Program (including Contributions) may always be
+Distributed subject to the version of the Agreement under which it was
+received. In addition, after a new version of the Agreement is published,
+Contributor may elect to Distribute the Program (including its
+Contributions) under the new version.
+
+Except as expressly stated in Sections 2(a) and 2(b) above, Recipient
+receives no rights or licenses to the intellectual property of any
+Contributor under this Agreement, whether expressly, by implication,
+estoppel or otherwise. All rights in the Program not expressly granted
+under this Agreement are reserved. Nothing in this Agreement is intended
+to be enforceable by any entity that is not a Contributor or Recipient.
+No third-party beneficiary rights are created under this Agreement.
+
+Exhibit A - Form of Secondary Licenses Notice
+
+"This Source Code may also be made available under the following
+Secondary Licenses when the conditions for such availability set forth
+in the Eclipse Public License, v. 2.0 are satisfied: {name license(s),
+version(s), and exceptions or additional permissions here}."
+
+  Simply including a copy of this Agreement, including this Exhibit A
+  is not sufficient to license the Source Code under Secondary Licenses.
+
+  If it is not possible or desirable to put the notice in a particular
+  file, then You may include the notice in a location (such as a LICENSE
+  file in a relevant directory) where a recipient would be likely to
+  look for such a notice.
+
+  You may add additional accurate notices of copyright ownership.

+options.SetAutoReconnect(true) functionality (token.Error() will return nil). Attempts will be made to re-deliver the
+message but there is currently no easy way know when such messages are delivered.
+
+If using Mosquitto then there are a range of fairly common issues:
+* `listener` - By default [Mosquitto v2+](https://mosquitto.org/documentation/migrating-to-2-0/) listens on loopback 
+interfaces only (meaning it will only accept connections made from the computer its running on).
+* `max_inflight_messages` - Unless this is set to 1 mosquitto does not guarantee ordered delivery of messages. 
+* `max_queued_messages` / `max_queued_bytes` - These impose limits on the number/size of queued messages. The defaults
+may lead to messages being silently dropped.
+* `persistence` - Defaults to false (messages will not survive a broker restart)
+* `max_keepalive` - defaults to 65535 and, from version 2.0.12, `SetKeepAlive(0)` will result in a rejected connection 
+by default.

-Eclipse Public License - v 1.0
-
-THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
-
-1. DEFINITIONS
-
-"Contribution" means:
-
-a) in the case of the initial Contributor, the initial code and documentation distributed under this Agreement, and
-b) in the case of each subsequent Contributor:
-i) changes to the Program, and
-ii) additions to the Program;
-where such changes and/or additions to the Program originate from and are distributed by that particular Contributor. A Contribution 'originates' from a Contributor if it was added to the Program by such Contributor itself or anyone acting on such Contributor's behalf. Contributions do not include additions to the Program which: (i) are separate modules of software distributed in conjunction with the Program under their own license agreement, and (ii) are not derivative works of the Program.
-"Contributor" means any person or entity that distributes the Program.
-
-"Licensed Patents" mean patent claims licensable by a Contributor which are necessarily infringed by the use or sale of its Contribution alone or when combined with the Program.
-
-"Program" means the Contributions distributed in accordance with this Agreement.
-
-"Recipient" means anyone who receives the Program under this Agreement, including all Contributors.
-
-2. GRANT OF RIGHTS
-
-a) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, distribute and sublicense the Contribution of such Contributor, if any, and such derivative works, in source code and object code form.
-b) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free patent license under Licensed Patents to make, use, sell, offer to sell, import and otherwise transfer the Contribution of such Contributor, if any, in source code and object code form. This patent license shall apply to the combination of the Contribution and the Program if, at the time the Contribution is added by the Contributor, such addition of the Contribution causes such combination to be covered by the Licensed Patents. The patent license shall not apply to any other combinations which include the Contribution. No hardware per se is licensed hereunder.
-c) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property rights of any other entity. Each Contributor disclaims any liability to Recipient for claims brought by any other entity based on infringement of intellectual property rights or otherwise. As a condition to exercising the rights and licenses granted hereunder, each Recipient hereby assumes sole responsibility to secure any other intellectual property rights needed, if any. For example, if a third party patent license is required to allow Recipient to distribute the Program, it is Recipient's responsibility to acquire that license before distributing the Program.
-d) Each Contributor represents that to its knowledge it has sufficient copyright rights in its Contribution, if any, to grant the copyright license set forth in this Agreement.
-3. REQUIREMENTS
-
-A Contributor may choose to distribute the Program in object code form under its own license agreement, provided that:
-
-a) it complies with the terms and conditions of this Agreement; and
-b) its license agreement:
-i) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and fitness for a particular purpose;
-ii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, incidental and consequential damages, such as lost profits;
-iii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any other party; and
-iv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it in a reasonable manner on or through a medium customarily used for software exchange.
-When the Program is made available in source code form:
-
-a) it must be made available under this Agreement; and
-b) a copy of this Agreement must be included with each copy of the Program.
-Contributors may not remove or alter any copyright notices contained within the Program.
-
-Each Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows subsequent Recipients to identify the originator of the Contribution.
-
-4. COMMERCIAL DISTRIBUTION
-
-Commercial distributors of software may accept certain responsibilities with respect to end users, business partners and the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes the Program in a commercial product offering should do so in a manner which does not create potential liability for other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor ("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may participate in any such claim at its own expense.
-
-For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, the Commercial Contributor must pay those damages.
-
-5. NO WARRANTY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely responsible for determining the appropriateness of using and distributing the Program and assumes all risks associated with its exercise of rights under this Agreement , including but not limited to the risks and costs of program errors, compliance with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations.
-
-6. DISCLAIMER OF LIABILITY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
-
-7. GENERAL
-
-If any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.
-
-If Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such litigation is filed.
-
-All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses granted by Recipient relating to the Program shall continue and survive.
-
-Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the right to modify this Agreement. The Eclipse Foundation is the initial Agreement Steward. The Eclipse Foundation may assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the Agreement will be given a distinguishing version number. The Program (including Contributions) may always be distributed subject to the version of the Agreement under which it was received. In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or otherwise. All rights in the Program not expressly granted under this Agreement are reserved.
-

+Eclipse Public License - v 2.0
+
+    THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE
+    PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION
+    OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
+
+1. DEFINITIONS
+
+"Contribution" means:
+
+  a) in the case of the initial Contributor, the initial content
+     Distributed under this Agreement, and
+
+  b) in the case of each subsequent Contributor:
+     i) changes to the Program, and
+     ii) additions to the Program;
+  where such changes and/or additions to the Program originate from
+  and are Distributed by that particular Contributor. A Contribution
+  "originates" from a Contributor if it was added to the Program by
+  such Contributor itself or anyone acting on such Contributor's behalf.
+  Contributions do not include changes or additions to the Program that
+  are not Modified Works.
+
+"Contributor" means any person or entity that Distributes the Program.
+
+"Licensed Patents" mean patent claims licensable by a Contributor which
+are necessarily infringed by the use or sale of its Contribution alone
+or when combined with the Program.
+
+"Program" means the Contributions Distributed in accordance with this
+Agreement.
+
+"Recipient" means anyone who receives the Program under this Agreement
+or any Secondary License (as applicable), including Contributors.
+
+"Derivative Works" shall mean any work, whether in Source Code or other
+form, that is based on (or derived from) the Program and for which the
+editorial revisions, annotations, elaborations, or other modifications
+represent, as a whole, an original work of authorship.
+
+"Modified Works" shall mean any work in Source Code or other form that
+results from an addition to, deletion from, or modification of the
+contents of the Program, including, for purposes of clarity any new file
+in Source Code form that contains any contents of the Program. Modified
+Works shall not include works that contain only declarations,
+interfaces, types, classes, structures, or files of the Program solely
+in each case in order to link to, bind by name, or subclass the Program
+or Modified Works thereof.
+
+"Distribute" means the acts of a) distributing or b) making available
+in any manner that enables the transfer of a copy.
+
+"Source Code" means the form of a Program preferred for making
+modifications, including but not limited to software source code,
+documentation source, and configuration files.
+
+"Secondary License" means either the GNU General Public License,
+Version 2.0, or any later versions of that license, including any
+exceptions or additional permissions as identified by the initial
+Contributor.
+
+2. GRANT OF RIGHTS
+
+  a) Subject to the terms of this Agreement, each Contributor hereby
+  grants Recipient a non-exclusive, worldwide, royalty-free copyright
+  license to reproduce, prepare Derivative Works of, publicly display,
+  publicly perform, Distribute and sublicense the Contribution of such
+  Contributor, if any, and such Derivative Works.
+
+  b) Subject to the terms of this Agreement, each Contributor hereby
+  grants Recipient a non-exclusive, worldwide, royalty-free patent
+  license under Licensed Patents to make, use, sell, offer to sell,
+  import and otherwise transfer the Contribution of such Contributor,
+  if any, in Source Code or other form. This patent license shall
+  apply to the combination of the Contribution and the Program if, at
+  the time the Contribution is added by the Contributor, such addition
+  of the Contribution causes such combination to be covered by the
+  Licensed Patents. The patent license shall not apply to any other
+  combinations which include the Contribution. No hardware per se is
+  licensed hereunder.
+
+  c) Recipient understands that although each Contributor grants the
+  licenses to its Contributions set forth herein, no assurances are
+  provided by any Contributor that the Program does not infringe the
+  patent or other intellectual property rights of any other entity.
+  Each Contributor disclaims any liability to Recipient for claims
+  brought by any other entity based on infringement of intellectual
+  property rights or otherwise. As a condition to exercising the
+  rights and licenses granted hereunder, each Recipient hereby
+  assumes sole responsibility to secure any other intellectual
+  property rights needed, if any. For example, if a third party
+  patent license is required to allow Recipient to Distribute the
+  Program, it is Recipient's responsibility to acquire that license
+  before distributing the Program.
+
+  d) Each Contributor represents that to its knowledge it has
+  sufficient copyright rights in its Contribution, if any, to grant
+  the copyright license set forth in this Agreement.
+
+  e) Notwithstanding the terms of any Secondary License, no
+  Contributor makes additional grants to any Recipient (other than
+  those set forth in this Agreement) as a result of such Recipient's
+  receipt of the Program under the terms of a Secondary License
+  (if permitted under the terms of Section 3).
+
+3. REQUIREMENTS
+
+3.1 If a Contributor Distributes the Program in any form, then:
+
+  a) the Program must also be made available as Source Code, in
+  accordance with section 3.2, and the Contributor must accompany
+  the Program with a statement that the Source Code for the Program
+  is available under this Agreement, and informs Recipients how to
+  obtain it in a reasonable manner on or through a medium customarily
+  used for software exchange; and
+
+  b) the Contributor may Distribute the Program under a license
+  different than this Agreement, provided that such license:
+     i) effectively disclaims on behalf of all other Contributors all
+     warranties and conditions, express and implied, including
+     warranties or conditions of title and non-infringement, and
+     implied warranties or conditions of merchantability and fitness
+     for a particular purpose;
+
+     ii) effectively excludes on behalf of all other Contributors all
+     liability for damages, including direct, indirect, special,
+     incidental and consequential damages, such as lost profits;
+
+     iii) does not attempt to limit or alter the recipients' rights
+     in the Source Code under section 3.2; and
+
+     iv) requires any subsequent distribution of the Program by any
+     party to be under a license that satisfies the requirements
+     of this section 3.
+
+3.2 When the Program is Distributed as Source Code:
+
+  a) it must be made available under this Agreement, or if the
+  Program (i) is combined with other material in a separate file or
+  files made available under a Secondary License, and (ii) the initial
+  Contributor attached to the Source Code the notice described in
+  Exhibit A of this Agreement, then the Program may be made available
+  under the terms of such Secondary Licenses, and
+
+  b) a copy of this Agreement must be included with each copy of
+  the Program.
+
+3.3 Contributors may not remove or alter any copyright, patent,
+trademark, attribution notices, disclaimers of warranty, or limitations
+of liability ("notices") contained within the Program from any copy of
+the Program which they Distribute, provided that Contributors may add
+their own appropriate notices.
+
+4. COMMERCIAL DISTRIBUTION
+
+Commercial distributors of software may accept certain responsibilities
+with respect to end users, business partners and the like. While this
+license is intended to facilitate the commercial use of the Program,
+the Contributor who includes the Program in a commercial product
+offering should do so in a manner which does not create potential
+liability for other Contributors. Therefore, if a Contributor includes
+the Program in a commercial product offering, such Contributor
+("Commercial Contributor") hereby agrees to defend and indemnify every
+other Contributor ("Indemnified Contributor") against any losses,
+damages and costs (collectively "Losses") arising from claims, lawsuits
+and other legal actions brought by a third party against the Indemnified
+Contributor to the extent caused by the acts or omissions of such
+Commercial Contributor in connection with its distribution of the Program
+in a commercial product offering. The obligations in this section do not
+apply to any claims or Losses relating to any actual or alleged
+intellectual property infringement. In order to qualify, an Indemnified
+Contributor must: a) promptly notify the Commercial Contributor in
+writing of such claim, and b) allow the Commercial Contributor to control,
+and cooperate with the Commercial Contributor in, the defense and any
+related settlement negotiations. The Indemnified Contributor may
+participate in any such claim at its own expense.
+
+For example, a Contributor might include the Program in a commercial
+product offering, Product X. That Contributor is then a Commercial
+Contributor. If that Commercial Contributor then makes performance
+claims, or offers warranties related to Product X, those performance
+claims and warranties are such Commercial Contributor's responsibility
+alone. Under this section, the Commercial Contributor would have to
+defend claims against the other Contributors related to those performance
+claims and warranties, and if a court requires any other Contributor to
+pay any damages as a result, the Commercial Contributor must pay
+those damages.
+
+5. NO WARRANTY
+
+EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
+PERMITTED BY APPLICABLE LAW, THE PROGRAM IS PROVIDED ON AN "AS IS"
+BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR
+IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF
+TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR
+PURPOSE. Each Recipient is solely responsible for determining the
+appropriateness of using and distributing the Program and assumes all
+risks associated with its exercise of rights under this Agreement,
+including but not limited to the risks and costs of program errors,
+compliance with applicable laws, damage to or loss of data, programs
+or equipment, and unavailability or interruption of operations.
+
+6. DISCLAIMER OF LIABILITY
+
+EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
+PERMITTED BY APPLICABLE LAW, NEITHER RECIPIENT NOR ANY CONTRIBUTORS
+SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
+EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST
+PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN
+CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE)
+ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE
+EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+7. GENERAL
+
+If any provision of this Agreement is invalid or unenforceable under
+applicable law, it shall not affect the validity or enforceability of
+the remainder of the terms of this Agreement, and without further
+action by the parties hereto, such provision shall be reformed to the
+minimum extent necessary to make such provision valid and enforceable.
+
+If Recipient institutes patent litigation against any entity
+(including a cross-claim or counterclaim in a lawsuit) alleging that the
+Program itself (excluding combinations of the Program with other software
+or hardware) infringes such Recipient's patent(s), then such Recipient's
+rights granted under Section 2(b) shall terminate as of the date such
+litigation is filed.
+
+All Recipient's rights under this Agreement shall terminate if it
+fails to comply with any of the material terms or conditions of this
+Agreement and does not cure such failure in a reasonable period of
+time after becoming aware of such noncompliance. If all Recipient's
+rights under this Agreement terminate, Recipient agrees to cease use
+and distribution of the Program as soon as reasonably practicable.
+However, Recipient's obligations under this Agreement and any licenses
+granted by Recipient relating to the Program shall continue and survive.
+
+Everyone is permitted to copy and distribute copies of this Agreement,
+but in order to avoid inconsistency the Agreement is copyrighted and
+may only be modified in the following manner. The Agreement Steward
+reserves the right to publish new versions (including revisions) of
+this Agreement from time to time. No one other than the Agreement
+Steward has the right to modify this Agreement. The Eclipse Foundation
+is the initial Agreement Steward. The Eclipse Foundation may assign the
+responsibility to serve as the Agreement Steward to a suitable separate
+entity. Each new version of the Agreement will be given a distinguishing
+version number. The Program (including Contributions) may always be
+Distributed subject to the version of the Agreement under which it was
+received. In addition, after a new version of the Agreement is published,
+Contributor may elect to Distribute the Program (including its
+Contributions) under the new version.
+
+Except as expressly stated in Sections 2(a) and 2(b) above, Recipient
+receives no rights or licenses to the intellectual property of any
+Contributor under this Agreement, whether expressly, by implication,
+estoppel or otherwise. All rights in the Program not expressly granted
+under this Agreement are reserved. Nothing in this Agreement is intended
+to be enforceable by any entity that is not a Contributor or Recipient.
+No third-party beneficiary rights are created under this Agreement.
+
+Exhibit A - Form of Secondary Licenses Notice
+
+"This Source Code may also be made available under the following
+Secondary Licenses when the conditions for such availability set forth
+in the Eclipse Public License, v. 2.0 are satisfied: {name license(s),
+version(s), and exceptions or additional permissions here}."
+
+  Simply including a copy of this Agreement, including this Exhibit A
+  is not sufficient to license the Source Code under Secondary Licenses.
+
+  If it is not possible or desirable to put the notice in a particular
+  file, then You may include the notice in a location (such as a LICENSE
+  file in a relevant directory) where a recipient would be likely to
+  look for such a notice.
+
+  You may add additional accurate notices of copyright ownership.

-   Specification, you further acknowledge your agreement to, and the acquisition of all necessary rights to permit the following:</p>
-
-<ol>
-       <li>A series of actions may occur (&quot;Provisioning Process&quot;) in which a user may execute the Provisioning Technology
-       on a machine (&quot;Target Machine&quot;) with the intent of installing, extending or updating the functionality of an Eclipse-based
-       product.</li>
-       <li>During the Provisioning Process, the Provisioning Technology may cause third party Installable Software or a portion thereof to be
-       accessed and copied to the Target Machine.</li>
-       <li>Pursuant to the Specification, you will provide to the user the terms and conditions that govern the use of the Installable
-       Software (&quot;Installable Software Agreement&quot;) and such Installable Software Agreement shall be accessed from the Target
-       Machine in accordance with the Specification. Such Installable Software Agreement must inform the user of the terms and conditions that govern
-       the Installable Software and must solicit acceptance by the end user in the manner prescribed in such Installable Software Agreement. Upon such
-       indication of agreement by the user, the provisioning Technology will complete installation of the Installable Software.</li>

-# Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/> [![Build Status](https://travis-ci.org/sirupsen/logrus.svg?branch=master)](https://travis-ci.org/sirupsen/logrus) [![GoDoc](https://godoc.org/github.com/sirupsen/logrus?status.svg)](https://godoc.org/github.com/sirupsen/logrus)
-
-Logrus is a structured logger for Go (golang), completely API compatible with
-the standard library logger.
-
-**Logrus is in maintenance-mode.** We will not be introducing new features. It's
-simply too hard to do in a way that won't break many people's projects, which is
-the last thing you want from your Logging library (again...).
-
-This does not mean Logrus is dead. Logrus will continue to be maintained for
-security, (backwards compatible) bug fixes, and performance (where we are
-limited by the interface). 
-
-I believe Logrus' biggest contribution is to have played a part in today's
-widespread use of structured logging in Golang. There doesn't seem to be a
-reason to do a major, breaking iteration into Logrus V2, since the fantastic Go
-community has built those independently. Many fantastic alternatives have sprung
-up. Logrus would look like those, had it been re-designed with what we know
-about structured logging in Go today. Check out, for example,
-[Zerolog][zerolog], [Zap][zap], and [Apex][apex].
-
-[zerolog]: https://github.com/rs/zerolog
-[zap]: https://github.com/uber-go/zap
-[apex]: https://github.com/apex/log
-
-**Seeing weird case-sensitive problems?** It's in the past been possible to
-import Logrus as both upper- and lower-case. Due to the Go package environment,
-this caused issues in the community and we needed a standard. Some environments
-experienced problems with the upper-case variant, so the lower-case was decided.
-Everything using `logrus` will need to use the lower-case:
-`github.com/sirupsen/logrus`. Any package that isn't, should be changed.
-
-To fix Glide, see [these
-comments](https://github.com/sirupsen/logrus/issues/553#issuecomment-306591437).
-For an in-depth explanation of the casing issue, see [this
-comment](https://github.com/sirupsen/logrus/issues/570#issuecomment-313933276).
-
-Nicely color-coded in development (when a TTY is attached, otherwise just
-plain text):
-
-![Colored](http://i.imgur.com/PY7qMwd.png)
-
-With `log.SetFormatter(&log.JSONFormatter{})`, for easy parsing by logstash
-or Splunk:
-
-```json
-{"animal":"walrus","level":"info","msg":"A group of walrus emerges from the

-```
-
-With the default `log.SetFormatter(&log.TextFormatter{})` when a TTY is not
-attached, the output is compatible with the
-[logfmt](http://godoc.org/github.com/kr/logfmt) format:
-
-```text
-time="2015-03-26T01:27:38-04:00" level=debug msg="Started observing beach" animal=walrus number=8
-time="2015-03-26T01:27:38-04:00" level=info msg="A group of walrus emerges from the ocean" animal=walrus size=10
-time="2015-03-26T01:27:38-04:00" level=warning msg="The group's number increased tremendously!" number=122 omg=true
-time="2015-03-26T01:27:38-04:00" level=debug msg="Temperature changes" temperature=-4
-time="2015-03-26T01:27:38-04:00" level=panic msg="It's over 9000!" animal=orca size=9009
-time="2015-03-26T01:27:38-04:00" level=fatal msg="The ice breaks!" err=&{0x2082280c0 map[animal:orca size:9009] 2015-03-26 01:27:38.441574009 -0400 EDT panic It's over 9000!} number=100 omg=true
-```
-To ensure this behaviour even if a TTY is attached, set your formatter as follows:
-
-```go
-	log.SetFormatter(&log.TextFormatter{
-		DisableColors: true,
-		FullTimestamp: true,
-	})
-```
-
-#### Logging Method Name
-
-If you wish to add the calling method as a field, instruct the logger via:
-```go
-log.SetReportCaller(true)
-```
-This adds the caller as 'method' like so:
-
-```json
-{"animal":"penguin","level":"fatal","method":"github.com/sirupsen/arcticcreatures.migrate","msg":"a penguin swims by",
-"time":"2014-03-10 19:57:38.562543129 -0400 EDT"}
-```
-
-```text
-time="2015-03-26T01:27:38-04:00" level=fatal method=github.com/sirupsen/arcticcreatures.migrate msg="a penguin swims by" animal=penguin
-```
-Note that this does add measurable overhead - the cost will depend on the version of Go, but is
-between 20 and 40% in recent tests with 1.6 and 1.7.  You can validate this in your
-environment via benchmarks: 
-```
-go test -bench=.*CallerTracing
-```
-
-
-#### Case-sensitivity
-
-The organization's name was changed to lower-case--and this will not be changed
-back. If you are getting import conflicts due to case sensitivity, please use
-the lower-case import: `github.com/sirupsen/logrus`.
-
-#### Example
-
-The simplest way to use Logrus is simply the package-level exported logger:
-
-```go
-package main
-
-import (
-  log "github.com/sirupsen/logrus"
-)
-
-func main() {
-  log.WithFields(log.Fields{
-    "animal": "walrus",
-  }).Info("A walrus appears")
-}
-```
-
-Note that it's completely api-compatible with the stdlib logger, so you can
-replace your `log` imports everywhere with `log "github.com/sirupsen/logrus"`
-and you'll now have the flexibility of Logrus. You can customize it all you
-want:
-
-```go
-package main
-
-import (
-  "os"
-  log "github.com/sirupsen/logrus"
-)
-
-func init() {
-  // Log as JSON instead of the default ASCII formatter.
-  log.SetFormatter(&log.JSONFormatter{})
-
-  // Output to stdout instead of the default stderr
-  // Can be any io.Writer, see below for File example
-  log.SetOutput(os.Stdout)
-
-  // Only log the warning severity or above.
-  log.SetLevel(log.WarnLevel)
-}
-
-func main() {
-  log.WithFields(log.Fields{
-    "animal": "walrus",
-    "size":   10,
-  }).Info("A group of walrus emerges from the ocean")
-
-  log.WithFields(log.Fields{
-    "omg":    true,
-    "number": 122,
-  }).Warn("The group's number increased tremendously!")
-
-  log.WithFields(log.Fields{
-    "omg":    true,
-    "number": 100,
-  }).Fatal("The ice breaks!")
-
-  // A common pattern is to re-use fields between logging statements by re-using
-  // the logrus.Entry returned from WithFields()
-  contextLogger := log.WithFields(log.Fields{
-    "common": "this is a common field",
-    "other": "I also should be logged always",
-  })
-
-  contextLogger.Info("I'll be logged with common and other field")
-  contextLogger.Info("Me too")
-}
-```
-
-For more advanced usage such as logging to multiple locations from the same
-application, you can also create an instance of the `logrus` Logger:
-
-```go
-package main
-
-import (
-  "os"
-  "github.com/sirupsen/logrus"
-)
-
-// Create a new instance of the logger. You can have any number of instances.
-var log = logrus.New()
-
-func main() {
-  // The API for setting attributes is a little different than the package level
-  // exported logger. See Godoc.
-  log.Out = os.Stdout
-
-  // You could set this to any `io.Writer` such as a file
-  // file, err := os.OpenFile("logrus.log", os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0666)
-  // if err == nil {
-  //  log.Out = file
-  // } else {
-  //  log.Info("Failed to log to file, using default stderr")
-  // }
-
-  log.WithFields(logrus.Fields{
-    "animal": "walrus",
-    "size":   10,
-  }).Info("A group of walrus emerges from the ocean")
-}
-```
-
-#### Fields
-
-Logrus encourages careful, structured logging through logging fields instead of
-long, unparseable error messages. For example, instead of: `log.Fatalf("Failed
-to send event %s to topic %s with key %d")`, you should log the much more
-discoverable:
-
-```go
-log.WithFields(log.Fields{
-  "event": event,
-  "topic": topic,
-  "key": key,
-}).Fatal("Failed to send event")
-```
-
-We've found this API forces you to think about logging in a way that produces
-much more useful logging messages. We've been in countless situations where just
-a single added field to a log statement that was already there would've saved us
-hours. The `WithFields` call is optional.
-
-In general, with Logrus using any of the `printf`-family functions should be
-seen as a hint you should add a field, however, you can still use the
-`printf`-family functions with Logrus.
-
-#### Default Fields
-
-Often it's helpful to have fields _always_ attached to log statements in an
-application or parts of one. For example, you may want to always log the
-`request_id` and `user_ip` in the context of a request. Instead of writing
-`log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip})` on
-every line, you can create a `logrus.Entry` to pass around instead:
-
-```go
-requestLogger := log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip})
-requestLogger.Info("something happened on that request") # will log request_id and user_ip
-requestLogger.Warn("something not great happened")
-```
-
-#### Hooks
-
-You can add hooks for logging levels. For example to send errors to an exception
-tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to
-multiple places simultaneously, e.g. syslog.
-
-Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in
-`init`:
-
-```go
-import (
-  log "github.com/sirupsen/logrus"
-  "gopkg.in/gemnasium/logrus-airbrake-hook.v2" // the package is named "airbrake"
-  logrus_syslog "github.com/sirupsen/logrus/hooks/syslog"
-  "log/syslog"
-)
-
-func init() {
-
-  // Use the Airbrake hook to report errors that have Error severity or above to
-  // an exception tracker. You can create custom hooks, see the Hooks section.
-  log.AddHook(airbrake.NewHook(123, "xyz", "production"))
-
-  hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
-  if err != nil {
-    log.Error("Unable to connect to local syslog daemon")
-  } else {
-    log.AddHook(hook)
-  }
-}
-```
-Note: Syslog hook also support connecting to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). For the detail, please check the [syslog hook README](hooks/syslog/README.md).
-
-A list of currently known service hooks can be found in this wiki [page](https://github.com/sirupsen/logrus/wiki/Hooks)
-
-
-#### Level logging
-
-Logrus has seven logging levels: Trace, Debug, Info, Warning, Error, Fatal and Panic.
-
-```go
-log.Trace("Something very low level.")
-log.Debug("Useful debugging information.")
-log.Info("Something noteworthy happened!")
-log.Warn("You should probably take a look at this.")
-log.Error("Something failed but I'm not quitting.")
-// Calls os.Exit(1) after logging
-log.Fatal("Bye.")
-// Calls panic() after logging
-log.Panic("I'm bailing.")
-```
-
-You can set the logging level on a `Logger`, then it will only log entries with
-that severity or anything above it:
-
-```go
-// Will log anything that is info or above (warn, error, fatal, panic). Default.
-log.SetLevel(log.InfoLevel)
-```
-
-It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose
-environment if your application has that.
-
-#### Entries
-
-Besides the fields added with `WithField` or `WithFields` some fields are
-automatically added to all logging events:
-
-1. `time`. The timestamp when the entry was created.
-2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after
-   the `AddFields` call. E.g. `Failed to send event.`
-3. `level`. The logging level. E.g. `info`.
-
-#### Environments
-
-Logrus has no notion of environment.
-
-If you wish for hooks and formatters to only be used in specific environments,
-you should handle that yourself. For example, if your application has a global
-variable `Environment`, which is a string representation of the environment you
-could do:
-
-```go
-import (
-  log "github.com/sirupsen/logrus"
-)
-
-init() {
-  // do something here to set environment depending on an environment variable
-  // or command-line flag
-  if Environment == "production" {
-    log.SetFormatter(&log.JSONFormatter{})
-  } else {
-    // The TextFormatter is default, you don't actually have to do this.
-    log.SetFormatter(&log.TextFormatter{})
-  }
-}
-```
-
-This configuration is how `logrus` was intended to be used, but JSON in
-production is mostly only useful if you do log aggregation with tools like
-Splunk or Logstash.
-
-#### Formatters
-
-The built-in logging formatters are:
-
-* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise
-  without colors.
-  * *Note:* to force colored output when there is no TTY, set the `ForceColors`
-    field to `true`.  To force no colored output even if there is a TTY  set the
-    `DisableColors` field to `true`. For Windows, see
-    [github.com/mattn/go-colorable](https://github.com/mattn/go-colorable).
-  * When colors are enabled, levels are truncated to 4 characters by default. To disable
-    truncation set the `DisableLevelTruncation` field to `true`.
-  * When outputting to a TTY, it's often helpful to visually scan down a column where all the levels are the same width. Setting the `PadLevelText` field to `true` enables this behavior, by adding padding to the level text.
-  * All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#TextFormatter).
-* `logrus.JSONFormatter`. Logs fields as JSON.
-  * All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#JSONFormatter).
-
-Third party logging formatters:
-
-* [`FluentdFormatter`](https://github.com/joonix/log). Formats entries that can be parsed by Kubernetes and Google Container Engine.
-* [`GELF`](https://github.com/fabienm/go-logrus-formatters). Formats entries so they comply to Graylog's [GELF 1.1 specification](http://docs.graylog.org/en/2.4/pages/gelf.html).
-* [`logstash`](https://github.com/bshuster-repo/logrus-logstash-hook). Logs fields as [Logstash](http://logstash.net) Events.
-* [`prefixed`](https://github.com/x-cray/logrus-prefixed-formatter). Displays log entry source along with alternative layout.
-* [`zalgo`](https://github.com/aybabtme/logzalgo). Invoking the Power of Zalgo.
-* [`nested-logrus-formatter`](https://github.com/antonfisher/nested-logrus-formatter). Converts logrus fields to a nested structure.
-* [`powerful-logrus-formatter`](https://github.com/zput/zxcTool). get fileName, log's line number and the latest function's name when print log; Sava log to files.
-* [`caption-json-formatter`](https://github.com/nolleh/caption_json_formatter). logrus's message json formatter with human-readable caption added.
-
-You can define your formatter by implementing the `Formatter` interface,
-requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a
-`Fields` type (`map[string]interface{}`) with all your fields as well as the
-default ones (see Entries section above):
-
-```go
-type MyJSONFormatter struct {
-}
-
-log.SetFormatter(new(MyJSONFormatter))
-
-func (f *MyJSONFormatter) Format(entry *Entry) ([]byte, error) {
-  // Note this doesn't include Time, Level and Message which are available on
-  // the Entry. Consult `godoc` on information about those fields or read the
-  // source of the official loggers.
-  serialized, err := json.Marshal(entry.Data)
-    if err != nil {
-      return nil, fmt.Errorf("Failed to marshal fields to JSON, %w", err)
-    }
-  return append(serialized, '\n'), nil
-}
-```
-
-#### Logger as an `io.Writer`
-
-Logrus can be transformed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it.
-
-```go
-w := logger.Writer()
-defer w.Close()
-
-srv := http.Server{
-    // create a stdlib log.Logger that writes to
-    // logrus.Logger.
-    ErrorLog: log.New(w, "", 0),
-}
-```
-
-Each line written to that writer will be printed the usual way, using formatters
-and hooks. The level for those entries is `info`.
-
-This means that we can override the standard library logger easily:
-
-```go
-logger := logrus.New()
-logger.Formatter = &logrus.JSONFormatter{}
-
-// Use logrus for standard log output
-// Note that `log` here references stdlib's log
-// Not logrus imported under the name `log`.
-log.SetOutput(logger.Writer())
-```
-
-#### Rotation
-
-Log rotation is not provided with Logrus. Log rotation should be done by an
-external program (like `logrotate(8)`) that can compress and delete old log
-entries. It should not be a feature of the application-level logger.
-
-#### Tools
-
-| Tool | Description |
-| ---- | ----------- |
-|[Logrus Mate](https://github.com/gogap/logrus_mate)|Logrus mate is a tool for Logrus to manage loggers, you can initial logger's level, hook and formatter by config file, the logger will be generated with different configs in different environments.|
-|[Logrus Viper Helper](https://github.com/heirko/go-contrib/tree/master/logrusHelper)|An Helper around Logrus to wrap with spf13/Viper to load configuration with fangs! And to simplify Logrus configuration use some behavior of [Logrus Mate](https://github.com/gogap/logrus_mate). [sample](https://github.com/heirko/iris-contrib/blob/master/middleware/logrus-logger/example) |
-
-#### Testing
-
-Logrus has a built in facility for asserting the presence of log messages. This is implemented through the `test` hook and provides:
-
-* decorators for existing logger (`test.NewLocal` and `test.NewGlobal`) which basically just adds the `test` hook
-* a test logger (`test.NewNullLogger`) that just records log messages (and does not output any):
-
-```go
-import(
-  "github.com/sirupsen/logrus"
-  "github.com/sirupsen/logrus/hooks/test"
-  "github.com/stretchr/testify/assert"
-  "testing"
-)
-
-func TestSomething(t*testing.T){
-  logger, hook := test.NewNullLogger()
-  logger.Error("Helloerror")
-
-  assert.Equal(t, 1, len(hook.Entries))
-  assert.Equal(t, logrus.ErrorLevel, hook.LastEntry().Level)
-  assert.Equal(t, "Helloerror", hook.LastEntry().Message)
-
-  hook.Reset()
-  assert.Nil(t, hook.LastEntry())
-}
-```
-
-#### Fatal handlers
-
-Logrus can register one or more functions that will be called when any `fatal`
-level message is logged. The registered handlers will be executed before
-logrus performs an `os.Exit(1)`. This behavior may be helpful if callers need
-to gracefully shutdown. Unlike a `panic("Something went wrong...")` call which can be intercepted with a deferred `recover` a call to `os.Exit(1)` can not be intercepted.
-
-```
-...
-handler := func() {
-  // gracefully shutdown something...
-}
-logrus.RegisterExitHandler(handler)
-...
-```
-
-#### Thread safety
-
-By default, Logger is protected by a mutex for concurrent writes. The mutex is held when calling hooks and writing logs.
-If you are sure such locking is not needed, you can call logger.SetNoLock() to disable the locking.
-
-Situation when locking is not needed includes:
-
-* You have no hooks registered, or hooks calling is already thread-safe.
-
-* Writing to logger.Out is already thread-safe, for example:
-
-  1) logger.Out is protected by locks.
-
-  2) logger.Out is an os.File handler opened with `O_APPEND` flag, and every write is smaller than 4k. (This allows multi-thread/multi-process writing)
