+# @gar/promisify
+
+### Promisify an entire object or class instance
+
+This module leverages es6 Proxy and Reflect to promisify every function in an
+object or class instance.
+
+It assumes the callback that the function is expecting is the last
+parameter, and that it is an error-first callback with only one value,
+i.e. `(err, value) => ...`. This mirrors node's `util.promisify` method.
+
+In order that you can use it as a one-stop-shop for all your promisify
+needs, you can also pass it a function.  That function will be
+promisified as normal using node's built-in `util.promisify` method.
+
+[node's custom promisified
+functions](https://nodejs.org/api/util.html#util_custom_promisified_functions)
+will also be mirrored, further allowing this to be a drop-in replacement
+for the built-in `util.promisify`.
+
+### Examples
+
+Promisify an entire object
+
+```javascript
+
+const promisify = require('@gar/promisify')
+
+class Foo {
+  constructor (attr) {
+    this.attr = attr
+  }
+
+  double (input, cb) {
+    cb(null, input * 2)
+  }
+
+const foo = new Foo('baz')
+const promisified = promisify(foo)
+
+console.log(promisified.attr)
+console.log(await promisified.double(1024))
+```
+
+Promisify a function
+
+```javascript
+
+const promisify = require('@gar/promisify')
+
+function foo (a, cb) {
+  if (a !== 'bad') {
+    return cb(null, 'ok')
+  }
+  return cb('not ok')
+}
+
+const promisified = promisify(foo)
+
+// This will resolve to 'ok'
+promisified('good')
+
+// this will reject
+promisified('bad')
+```

+
+ - Updated request and hawk (#347)
+ - Dropped node v0.10.x support
+
+## 0.6.40
+
+ - Improved error reporting if an install fails
+
+## 0.6.39
+
+ - Support for node v9
+ - Support for versioning on `{libc}` to allow binaries to work on non-glic linux systems like alpine linux
+
+
+## 0.6.38
+
+ - Maintaining compatibility (for v0.6.x series) with node v0.10.x
+
+## 0.6.37
+
+ - Solved one part of #276: now now deduce the node ABI from the major version for node >= 2 even when not stored in the abi_crosswalk.json
+ - Fixed docs to avoid mentioning the deprecated and dangerous `prepublish` in package.json (#291)
+ - Add new node versions to crosswalk
+ - Ported tests to use tape instead of mocha
+ - Got appveyor tests passing by downgrading npm and node-gyp
+
+## 0.6.36
+
+ - Removed the running of `testbinary` during install. Because this was regressed for so long, it is too dangerous to re-enable by default. Developers needing validation can call `node-pre-gyp testbinary` directory.
+ - Fixed regression in v0.6.35 for electron installs (now skipping binary validation which is not yet supported for electron)
+
+## 0.6.35
+
+ - No longer recommending `npm ls` in `prepublish` (#291)
+ - Fixed testbinary command (#283) @szdavid92
+
+## 0.6.34
+
+ - Added new node versions to crosswalk, including v8
+ - Upgraded deps to latest versions, started using `^` instead of `~` for all deps.
+
+## 0.6.33
+
+ - Improved support for yarn
+
+## 0.6.32
+
+ - Honor npm configuration for CA bundles (@heikkipora)
+ - Add node-pre-gyp and npm versions to user agent (@addaleax)
+ - Updated various deps
+ - Add known node version for v7.x
+
+## 0.6.31
+
+ - Updated various deps
+
+## 0.6.30
+
+ - Update to npmlog@4.x and semver@5.3.x
+ - Add known node version for v6.5.0
+
+## 0.6.29
+
+ - Add known node versions for v0.10.45, v0.12.14, v4.4.4, v5.11.1, and v6.1.0
+
+## 0.6.28
+
+ - Now more verbose when remote binaries are not available. This is needed since npm is increasingly more quiet by default
+   and users need to know why builds are falling back to source compiles that might then error out.
+
+## 0.6.27
+
+ - Add known node version for node v6
+ - Stopped bundling dependencies
+ - Documented method for module authors to avoid bundling node-pre-gyp
+   - See https://github.com/mapbox/node-pre-gyp/tree/master#configuring for details
+
+## 0.6.26
+
+ - Skip validation for nw runtime (https://github.com/mapbox/node-pre-gyp/pull/181) via @fleg
+
+## 0.6.25
+
+ - Improved support for auto-detection of electron runtime in `node-pre-gyp.find()`
+   - Pull request from @enlight - https://github.com/mapbox/node-pre-gyp/pull/187
+ - Add known node version for 4.4.1 and 5.9.1
+
+## 0.6.24
+
+ - Add known node version for 5.8.0, 5.9.0, and 4.4.0.

+ - Add known node version for 4.3.1, and 5.7.0.
+
+## 0.6.21
+
+ - Add known node version for 0.10.42, 0.12.10, 4.3.0, and 5.6.0.
+
+## 0.6.20
+
+ - Add known node version for 4.2.5, 4.2.6, 5.4.0, 5.4.1,and 5.5.0.
+
+## 0.6.19
+
+ - Add known node version for 4.2.4

+# @mapbox/node-pre-gyp
+
+#### @mapbox/node-pre-gyp makes it easy to publish and install Node.js C++ addons from binaries
+
+[![Build Status](https://travis-ci.com/mapbox/node-pre-gyp.svg?branch=master)](https://travis-ci.com/mapbox/node-pre-gyp)
+[![Build status](https://ci.appveyor.com/api/projects/status/3nxewb425y83c0gv)](https://ci.appveyor.com/project/Mapbox/node-pre-gyp)
+
+`@mapbox/node-pre-gyp` stands between [npm](https://github.com/npm/npm) and [node-gyp](https://github.com/Tootallnate/node-gyp) and offers a cross-platform method of binary deployment.
+
+### Special note on previous package
+
+On Feb 9th, 2021 `@mapbox/node-pre-gyp@1.0.0` was [released](./CHANGELOG.md). Older, unscoped versions that are not part of the `@mapbox` org are deprecated and only `@mapbox/node-pre-gyp` will see updates going forward. To upgrade to the new package do:
+
+```
+npm uninstall node-pre-gyp --save
+npm install @mapbox/node-pre-gyp --save
+```
+
+### Features
+
+ - A command line tool called `node-pre-gyp` that can install your package's C++ module from a binary.
+ - A variety of developer targeted commands for packaging, testing, and publishing binaries.
+ - A JavaScript module that can dynamically require your installed binary: `require('@mapbox/node-pre-gyp').find`
+
+For a hello world example of a module packaged with `node-pre-gyp` see <https://github.com/springmeyer/node-addon-example> and [the wiki ](https://github.com/mapbox/node-pre-gyp/wiki/Modules-using-node-pre-gyp) for real world examples.
+
+## Credits
+
+ - The module is modeled after [node-gyp](https://github.com/Tootallnate/node-gyp) by [@Tootallnate](https://github.com/Tootallnate)
+ - Motivation for initial development came from [@ErisDS](https://github.com/ErisDS) and the [Ghost Project](https://github.com/TryGhost/Ghost).
+ - Development is sponsored by [Mapbox](https://www.mapbox.com/)
+
+## FAQ
+
+See the [Frequently Ask Questions](https://github.com/mapbox/node-pre-gyp/wiki/FAQ).
+
+## Depends
+
+ - Node.js >= node v8.x
+
+## Install
+
+`node-pre-gyp` is designed to be installed as a local dependency of your Node.js C++ addon and accessed like:
+
+    ./node_modules/.bin/node-pre-gyp --help
+
+But you can also install it globally:
+
+    npm install @mapbox/node-pre-gyp -g
+
+## Usage
+
+### Commands
+
+View all possible commands:
+
+    node-pre-gyp --help
+
+- clean - Remove the entire folder containing the compiled .node module
+- install - Install pre-built binary for module
+- reinstall - Run "clean" and "install" at once
+- build - Compile the module by dispatching to node-gyp or nw-gyp
+- rebuild - Run "clean" and "build" at once
+- package - Pack binary into tarball
+- testpackage - Test that the staged package is valid
+- publish - Publish pre-built binary
+- unpublish - Unpublish pre-built binary
+- info - Fetch info on published binaries
+
+You can also chain commands:
+
+    node-pre-gyp clean build unpublish publish info
+
+### Options
+
+Options include:
+
+ - `-C/--directory`: run the command in this directory
+ - `--build-from-source`: build from source instead of using pre-built binary
+ - `--update-binary`: reinstall by replacing previously installed local binary with remote binary
+ - `--runtime=node-webkit`: customize the runtime: `node`, `electron` and `node-webkit` are the valid options
+ - `--fallback-to-build`: fallback to building from source if pre-built binary is not available
+ - `--target=0.4.0`: Pass the target node or node-webkit version to compile against
+ - `--target_arch=ia32`: Pass the target arch and override the host `arch`. Any value that is [supported by Node.js](https://nodejs.org/api/os.html#osarch) is valid.
+ - `--target_platform=win32`: Pass the target platform and override the host `platform`. Valid values are `linux`, `darwin`, `win32`, `sunos`, `freebsd`, `openbsd`, and `aix`.
+
+Both `--build-from-source` and `--fallback-to-build` can be passed alone or they can provide values. You can pass `--fallback-to-build=false` to override the option as declared in package.json. In addition to being able to pass `--build-from-source` you can also pass `--build-from-source=myapp` where `myapp` is the name of your module.
+
+For example: `npm install --build-from-source=myapp`. This is useful if:
+
+ - `myapp` is referenced in the package.json of a larger app and therefore `myapp` is being installed as a dependency with `npm install`.
+ - The larger app also depends on other modules installed with `node-pre-gyp`
+ - You only want to trigger a source compile for `myapp` and the other modules.
+
+### Configuring
+
+This is a guide to configuring your module to use node-pre-gyp.
+
+#### 1) Add new entries to your `package.json`
+
+ - Add `@mapbox/node-pre-gyp` to `dependencies`
+ - Add `aws-sdk` as a `devDependency`
+ - Add a custom `install` script
+ - Declare a `binary` object
+
+This looks like:
+
+```js
+    "dependencies"  : {
+      "@mapbox/node-pre-gyp": "1.x"
+    },
+    "devDependencies": {
+      "aws-sdk": "2.x"
+    }
+    "scripts": {
+        "install": "node-pre-gyp install --fallback-to-build"
+    },
+    "binary": {
+        "module_name": "your_module",
+        "module_path": "./lib/binding/",
+        "host": "https://your_module.s3-us-west-1.amazonaws.com"
+    }
+```
+
+For a full example see [node-addon-examples's package.json](https://github.com/springmeyer/node-addon-example/blob/master/package.json).
+
+Let's break this down:
+
+ - Dependencies need to list `node-pre-gyp`
+ - Your devDependencies should list `aws-sdk` so that you can run `node-pre-gyp publish` locally or a CI system. We recommend using `devDependencies` only since `aws-sdk` is large and not needed for `node-pre-gyp install` since it only uses http to fetch binaries
+ - Your `scripts` section should override the `install` target with `"install": "node-pre-gyp install --fallback-to-build"`. This allows node-pre-gyp to be used instead of the default npm behavior of always source compiling with `node-gyp` directly.
+ - Your package.json should contain a `binary` section describing key properties you provide to allow node-pre-gyp to package optimally. They are detailed below.
+
+Note: in the past we recommended putting `@mapbox/node-pre-gyp` in the `bundledDependencies`, but we no longer recommend this. In the past there were npm bugs (with node versions 0.10.x) that could lead to node-pre-gyp not being available at the right time during install (unless we bundled). This should no longer be the case. Also, for a time we recommended using `"preinstall": "npm install @mapbox/node-pre-gyp"` as an alternative method to avoid needing to bundle. But this did not behave predictably across all npm versions - see https://github.com/mapbox/node-pre-gyp/issues/260 for the details. So we do not recommend using `preinstall` to install `@mapbox/node-pre-gyp`. More history on this at https://github.com/strongloop/fsevents/issues/157#issuecomment-265545908.
+
+##### The `binary` object has three required properties
+
+###### module_name
+
+The name of your native node module. This value must:
+
+ - Match the name passed to [the NODE_MODULE macro](http://nodejs.org/api/addons.html#addons_hello_world)
+ - Must be a valid C variable name (e.g. it cannot contain `-`)
+ - Should not include the `.node` extension.
+
+###### module_path
+
+The location your native module is placed after a build. This should be an empty directory without other Javascript files. This entire directory will be packaged in the binary tarball. When installing from a remote package this directory will be overwritten with the contents of the tarball.
+
+Note: This property supports variables based on [Versioning](#versioning).
+
+###### host
+
+A url to the remote location where you've published tarball binaries (must be `https` not `http`).
+
+It is highly recommended that you use Amazon S3. The reasons are:
+
+  - Various node-pre-gyp commands like `publish` and `info` only work with an S3 host.
+  - S3 is a very solid hosting platform for distributing large files.
+  - We provide detail documentation for using [S3 hosting](#s3-hosting) with node-pre-gyp.
+
+Why then not require S3? Because while some applications using node-pre-gyp need to distribute binaries as large as 20-30 MB, others might have very small binaries and might wish to store them in a GitHub repo. This is not recommended, but if an author really wants to host in a non-S3 location then it should be possible.
+
+It should also be mentioned that there is an optional and entirely separate npm module called [node-pre-gyp-github](https://github.com/bchr02/node-pre-gyp-github) which is intended to complement node-pre-gyp and be installed along with it. It provides the ability to store and publish your binaries within your repositories GitHub Releases if you would rather not use S3 directly. Installation and usage instructions can be found [here](https://github.com/bchr02/node-pre-gyp-github), but the basic premise is that instead of using the ```node-pre-gyp publish``` command you would use ```node-pre-gyp-github publish```.
+
+##### The `binary` object other optional S3 properties
+
+If you are not using a standard s3 path like `bucket_name.s3(.-)region.amazonaws.com`, you might get an error on `publish` because node-pre-gyp extracts the region and bucket from the `host` url. For example, you may have an on-premises s3-compatible storage  server, or may have configured a specific dns redirecting to an s3  endpoint. In these cases, you can explicitly set the `region` and `bucket` properties to tell node-pre-gyp to use these values instead of guessing from the `host` property. The following values can be used in the `binary` section:
+
+###### host
+
+The url to the remote server root location (must be `https` not `http`).
+
+###### bucket
+
+The bucket name where your tarball binaries should be located.
+
+###### region
+
+Your S3 server region.
+
+###### s3ForcePathStyle
+
+Set `s3ForcePathStyle` to true if the endpoint url should not be prefixed with the bucket name. If false (default), the server endpoint would be  constructed as `bucket_name.your_server.com`.
+
+##### The `binary` object has optional properties
+
+###### remote_path
+
+It **is recommended** that you customize this property. This is an extra path to use for publishing and finding remote tarballs. The default value for `remote_path` is `""` meaning that if you do not provide it then all packages will be published at the base of the `host`. It is recommended to provide a value like `./{name}/v{version}` to help organize remote packages in the case that you choose to publish multiple node addons to the same `host`.
+
+Note: This property supports variables based on [Versioning](#versioning).
+
+###### package_name
+
+It is **not recommended** to override this property unless you are also overriding the `remote_path`. This is the versioned name of the remote tarball containing the binary `.node` module and any supporting files you've placed inside the `module_path` directory. Unless you specify `package_name` in your `package.json` then it defaults to `{module_name}-v{version}-{node_abi}-{platform}-{arch}.tar.gz` which allows your binary to work across node versions, platforms, and architectures. If you are using `remote_path` that is also versioned by `./{module_name}/v{version}` then you could remove these variables from the `package_name` and just use: `{node_abi}-{platform}-{arch}.tar.gz`. Then your remote tarball will be looked up at, for example, `https://example.com/your-module/v0.1.0/node-v11-linux-x64.tar.gz`.
+
+Avoiding the version of your module in the `package_name` and instead only embedding in a directory name can be useful when you want to make a quick tag of your module that does not change any C++ code. In this case you can just copy binaries to the new version behind the scenes like:
+
+```sh
+aws s3 sync --acl public-read s3://mapbox-node-binary/sqlite3/v3.0.3/ s3://mapbox-node-binary/sqlite3/v3.0.4/
+```
+
+Note: This property supports variables based on [Versioning](#versioning).
+
+#### 2) Add a new target to binding.gyp
+
+`node-pre-gyp` calls out to `node-gyp` to compile the module and passes variables along like [module_name](#module_name) and [module_path](#module_path).
+
+A new target must be added to `binding.gyp` that moves the compiled `.node` module from `./build/Release/module_name.node` into the directory specified by `module_path`.
+
+Add a target like this at the end of your `targets` list:
+
+```js
+    {
+      "target_name": "action_after_build",
+      "type": "none",
+      "dependencies": [ "<(module_name)" ],
+      "copies": [
+        {
+          "files": [ "<(PRODUCT_DIR)/<(module_name).node" ],
+          "destination": "<(module_path)"
+        }
+      ]
+    }
+```
+
+For a full example see [node-addon-example's binding.gyp](https://github.com/springmeyer/node-addon-example/blob/2ff60a8ded7f042864ad21db00c3a5a06cf47075/binding.gyp).
+
+#### 3) Dynamically require your `.node`
+
+Inside the main js file that requires your addon module you are likely currently doing:
+
+```js
+var binding = require('../build/Release/binding.node');
+```
+
+or:
+
+```js
+var bindings = require('./bindings')
+```
+
+Change those lines to:
+
+```js
+var binary = require('@mapbox/node-pre-gyp');
+var path = require('path');
+var binding_path = binary.find(path.resolve(path.join(__dirname,'./package.json')));
+var binding = require(binding_path);
+```
+
+For a full example see [node-addon-example's index.js](https://github.com/springmeyer/node-addon-example/blob/2ff60a8ded7f042864ad21db00c3a5a06cf47075/index.js#L1-L4)
+
+#### 4) Build and package your app
+
+Now build your module from source:
+
+    npm install --build-from-source
+
+The `--build-from-source` tells `node-pre-gyp` to not look for a remote package and instead dispatch to node-gyp to build.
+
+Now `node-pre-gyp` should now also be installed as a local dependency so the command line tool it offers can be found at `./node_modules/.bin/node-pre-gyp`.
+
+#### 5) Test
+
+Now `npm test` should work just as it did before.
+
+#### 6) Publish the tarball
+
+Then package your app:
+
+    ./node_modules/.bin/node-pre-gyp package
+
+Once packaged, now you can publish:
+
+    ./node_modules/.bin/node-pre-gyp publish
+
+Currently the `publish` command pushes your binary to S3. This requires:
+
+ - You have installed `aws-sdk` with `npm install aws-sdk`
+ - You have created a bucket already.
+ - The `host` points to an S3 http or https endpoint.
+ - You have configured node-pre-gyp to read your S3 credentials (see [S3 hosting](#s3-hosting) for details).
+
+You can also host your binaries elsewhere. To do this requires:
+
+ - You manually publish the binary created by the `package` command to an `https` endpoint
+ - Ensure that the `host` value points to your custom `https` endpoint.
+
+#### 7) Automate builds
+
+Now you need to publish builds for all the platforms and node versions you wish to support. This is best automated.
+
+ - See [Appveyor Automation](#appveyor-automation) for how to auto-publish builds on Windows.
+ - See [Travis Automation](#travis-automation) for how to auto-publish builds on OS X and Linux.
+
+#### 8) You're done!
+
+Now publish your module to the npm registry. Users will now be able to install your module from a binary.
+
+What will happen is this:
+
+1. `npm install <your package>` will pull from the npm registry
+2. npm will run the `install` script which will call out to `node-pre-gyp`
+3. `node-pre-gyp` will fetch the binary `.node` module and unpack in the right place
+4. Assuming that all worked, you are done
+
+If a a binary was not available for a given platform and `--fallback-to-build` was used then `node-gyp rebuild` will be called to try to source compile the module.
+
+#### 9) One more option
+
+It may be that you want to work with two s3 buckets, one for staging and one for production; this
+arrangement makes it less likely to accidentally overwrite a production binary. It also allows the production
+environment to have more restrictive permissions than staging while still enabling publishing when
+developing and testing.
+
+The binary.host property can be set at execution time. In order to do so all of the following conditions
+must be true.
+
+- binary.host is falsey or not present
+- binary.staging_host is not empty
+- binary.production_host is not empty
+
+If any of these checks fail then the operation will not perform execution time determination of the s3 target.
+
+If the command being executed is either "publish" or "unpublish" then the default is set to `binary.staging_host`. In all other cases
+the default is `binary.production_host`.
+
+The command-line options `--s3_host=staging` or `--s3_host=production` override the default. If `s3_host`
+is present and not `staging` or `production` an exception is thrown.
+
+This allows installing from staging by specifying `--s3_host=staging`. And it requires specifying
+`--s3_option=production` in order to publish to, or unpublish from, production, making accidental errors less likely.
+
+## Node-API Considerations

+[Node-API](https://nodejs.org/api/n-api.html#n_api_node_api), which was previously known as N-API, is an ABI-stable alternative to previous technologies such as [nan](https://github.com/nodejs/nan) which are tied to a specific Node runtime engine. Node-API is Node runtime engine agnostic and guarantees modules created today will continue to run, without changes, into the future.
+
+Using `node-pre-gyp` with Node-API projects requires a handful of additional configuration values and imposes some additional requirements.
+
+The most significant difference is that an Node-API module can be coded to target multiple  Node-API versions. Therefore, an Node-API module must declare in its `package.json` file which Node-API versions the module is designed to run against. In addition, since multiple builds may be required for a single module, path and file names must be specified in way that avoids naming conflicts.
+
+### The `napi_versions` array property
+
+A Node-API module must declare in its `package.json` file, the Node-API versions the module is intended to support. This is accomplished by including an `napi-versions` array property in the `binary` object. For example:
+
+```js
+"binary": {
+    "module_name": "your_module",
+    "module_path": "your_module_path",
+    "host": "https://your_bucket.s3-us-west-1.amazonaws.com",
+    "napi_versions": [1,3]
+  }
+```
+
+If the `napi_versions` array property is *not* present, `node-pre-gyp` operates as it always has. Including the `napi_versions` array property instructs `node-pre-gyp` that this is a Node-API module build.
+
+When the `napi_versions` array property is present, `node-pre-gyp` fires off multiple operations, one for each of the Node-API versions in the array. In the example above, two operations are initiated, one for Node-API version 1 and second for Node-API version 3. How this version number is communicated is described next.
+
+### The `napi_build_version` value
+
+For each of the Node-API module operations `node-pre-gyp` initiates, it ensures that the `napi_build_version` is set appropriately.
+
+This value is of importance in two areas:
+
+1. The C/C++ code which needs to know against which Node-API version it should compile.
+2. `node-pre-gyp` itself which must assign appropriate path and file names to avoid collisions.
+
+### Defining `NAPI_VERSION` for the C/C++ code
+
+The `napi_build_version` value is communicated to the C/C++ code by adding this code to the `binding.gyp` file:
+
+```
+"defines": [
+    "NAPI_VERSION=<(napi_build_version)",
+]
+```
+
+This ensures that `NAPI_VERSION`, an integer value, is declared appropriately to the C/C++ code for each build.
+
+> Note that earlier versions of this document recommended defining the symbol `NAPI_BUILD_VERSION`. `NAPI_VERSION` is preferred because it used by the Node-API C/C++ headers to configure the specific Node-API versions being requested.
+
+### Path and file naming requirements in `package.json`
+
+Since `node-pre-gyp` fires off multiple operations for each request, it is essential that path and file names be created in such a way as to avoid collisions. This is accomplished by imposing additional path and file naming requirements.
+
+Specifically, when performing Node-API builds, the `{napi_build_version}` text configuration value  *must* be present in the `module_path` property. In addition, the `{napi_build_version}` text configuration value  *must* be present in either the `remote_path` or `package_name` property. (No problem if it's in both.)
+
+Here's an example:
+
+```js
+"binary": {
+    "module_name": "your_module",
+    "module_path": "./lib/binding/napi-v{napi_build_version}",
+    "remote_path": "./{module_name}/v{version}/{configuration}/",
+    "package_name": "{platform}-{arch}-napi-v{napi_build_version}.tar.gz",
+    "host": "https://your_bucket.s3-us-west-1.amazonaws.com",
+    "napi_versions": [1,3]
+  }
+```
+
+## Supporting both Node-API and NAN builds
+
+You may have a legacy native add-on that you wish to continue supporting for those versions of Node that do not support Node-API, as you add Node-API support for later Node versions. This can be accomplished by specifying the `node_napi_label` configuration value in the package.json `binary.package_name` property.
+
+Placing the configuration value `node_napi_label` in the package.json `binary.package_name` property instructs `node-pre-gyp` to build all viable Node-API binaries supported by the current Node instance. If the current Node instance does not support Node-API, `node-pre-gyp` will request a traditional, non-Node-API build.
+
+The configuration value `node_napi_label` is set by `node-pre-gyp` to the type of build created, `napi` or `node`, and the version number. For Node-API builds, the string contains the Node-API version nad has values like `napi-v3`. For traditional, non-Node-API builds, the string contains the ABI version with values like `node-v46`.
+
+Here's how the `binary` configuration above might be changed to support both Node-API and NAN builds:
+
+```js
+"binary": {
+    "module_name": "your_module",
+    "module_path": "./lib/binding/{node_napi_label}",
+    "remote_path": "./{module_name}/v{version}/{configuration}/",
+    "package_name": "{platform}-{arch}-{node_napi_label}.tar.gz",
+    "host": "https://your_bucket.s3-us-west-1.amazonaws.com",
+    "napi_versions": [1,3]
+  }
+```
+
+The C/C++ symbol `NAPI_VERSION` can be used to distinguish Node-API and non-Node-API builds. The value of `NAPI_VERSION` is set to the integer Node-API version for Node-API builds and is set to `0` for non-Node-API builds.
+
+For example:
+
+```C
+#if NAPI_VERSION
+// Node-API code goes here
+#else
+// NAN code goes here
+#endif
+```
+
+### Two additional configuration values
+
+The following two configuration values, which were implemented in previous versions of `node-pre-gyp`, continue to exist, but have been replaced by the `node_napi_label` configuration value described above.
+
+1. `napi_version` If Node-API is supported by the currently executing Node instance, this value is the Node-API version number supported by Node. If Node-API is not supported, this value is an empty string.
+
+2. `node_abi_napi` If the value returned for `napi_version` is non empty, this value is `'napi'`. If the value returned for `napi_version` is empty, this value is the value returned for `node_abi`.
+
+These values are present for use in the `binding.gyp` file and may be used as `{napi_version}` and `{node_abi_napi}` for text substituion in the `binary` properties of the `package.json` file.
+
+## S3 Hosting
+
+You can host wherever you choose but S3 is cheap, `node-pre-gyp publish` expects it, and S3 can be integrated well with [Travis.ci](http://travis-ci.org) to automate builds for OS X and Ubuntu, and with [Appveyor](http://appveyor.com) to automate builds for Windows. Here is an approach to do this:
+
+First, get setup locally and test the workflow:
+
+#### 1) Create an S3 bucket
+
+And have your **key** and **secret key** ready for writing to the bucket.
+
+It is recommended to create a IAM user with a policy that only gives permissions to the specific bucket you plan to publish to. This can be done in the [IAM console](https://console.aws.amazon.com/iam/) by: 1) adding a new user, 2) choosing `Attach User Policy`, 3) Using the `Policy Generator`, 4) selecting `Amazon S3` for the service, 5) adding the actions: `DeleteObject`, `GetObject`, `GetObjectAcl`, `ListBucket`, `HeadBucket`, `PutObject`, `PutObjectAcl`, 6) adding an ARN of `arn:aws:s3:::bucket/*` (replacing `bucket` with your bucket name), and finally 7) clicking `Add Statement` and saving the policy. It should generate a policy like:
+
+```js
+{
+    "Version": "2012-10-17",
+    "Statement": [
+        {
+            "Sid": "objects",
+            "Effect": "Allow",
+            "Action": [
+                "s3:PutObject",
+                "s3:GetObjectAcl",
+                "s3:GetObject",
+                "s3:DeleteObject",
+                "s3:PutObjectAcl"
+            ],
+            "Resource": "arn:aws:s3:::your-bucket-name/*"
+        },
+        {
+            "Sid": "bucket",
+            "Effect": "Allow",
+            "Action": "s3:ListBucket",
+            "Resource": "arn:aws:s3:::your-bucket-name"
+        },
+        {
+            "Sid": "buckets",
+            "Effect": "Allow",
+            "Action": "s3:HeadBucket",
+            "Resource": "*"
+        }
+    ]
+}
+```
+
+#### 2) Install node-pre-gyp
+
+Either install it globally:
+
+    npm install node-pre-gyp -g
+
+Or put the local version on your PATH
+
+    export PATH=`pwd`/node_modules/.bin/:$PATH
+
+#### 3) Configure AWS credentials
+
+It is recommended to configure the AWS JS SDK v2 used internally by `node-pre-gyp` by setting these environment variables:
+
+- AWS_ACCESS_KEY_ID
+- AWS_SECRET_ACCESS_KEY
+
+But also you can also use the `Shared Config File` mentioned [in the AWS JS SDK v2 docs](https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/configuring-the-jssdk.html)
+
+#### 4) Package and publish your build
+
+Install the `aws-sdk`:
+
+    npm install aws-sdk
+
+Then publish:
+
+    node-pre-gyp package publish
+
+Note: if you hit an error like `Hostname/IP doesn't match certificate's altnames` it may mean that you need to provide the `region` option in your config.
+
+## Appveyor Automation
+
+[Appveyor](http://www.appveyor.com/) can build binaries and publish the results per commit and supports:
+
+ - Windows Visual Studio 2013 and related compilers
+ - Both 64 bit (x64) and 32 bit (x86) build configurations
+ - Multiple Node.js versions
+
+For an example of doing this see [node-sqlite3's appveyor.yml](https://github.com/mapbox/node-sqlite3/blob/master/appveyor.yml).
+
+Below is a guide to getting set up:
+
+#### 1) Create a free Appveyor account
+
+Go to https://ci.appveyor.com/signup/free and sign in with your GitHub account.
+
+#### 2) Create a new project
+
+Go to https://ci.appveyor.com/projects/new and select the GitHub repo for your module
+
+#### 3) Add appveyor.yml and push it
+
+Once you have committed an `appveyor.yml` ([appveyor.yml reference](http://www.appveyor.com/docs/appveyor-yml)) to your GitHub repo and pushed it AppVeyor should automatically start building your project.
+
+#### 4) Create secure variables
+
+Encrypt your S3 AWS keys by going to <https://ci.appveyor.com/tools/encrypt> and hitting the `encrypt` button.
+
+Then paste the result into your `appveyor.yml`
+
+```yml
+environment:
+  AWS_ACCESS_KEY_ID:
+    secure: Dn9HKdLNYvDgPdQOzRq/DqZ/MPhjknRHB1o+/lVU8MA=
+  AWS_SECRET_ACCESS_KEY:
+    secure: W1rwNoSnOku1r+28gnoufO8UA8iWADmL1LiiwH9IOkIVhDTNGdGPJqAlLjNqwLnL
+```
+
+NOTE: keys are per account but not per repo (this is difference than Travis where keys are per repo but not related to the account used to encrypt them).
+
+#### 5) Hook up publishing
+
+Just put `node-pre-gyp package publish` in your `appveyor.yml` after `npm install`.
+
+#### 6) Publish when you want
+
+You might wish to publish binaries only on a specific commit. To do this you could borrow from the [Travis CI idea of commit keywords](http://about.travis-ci.org/docs/user/how-to-skip-a-build/) and add special handling for commit messages with `[publish binary]`:
+
+    SET CM=%APPVEYOR_REPO_COMMIT_MESSAGE%
+    if not "%CM%" == "%CM:[publish binary]=%" node-pre-gyp --msvs_version=2013 publish
+
+If your commit message contains special characters (e.g. `&`) this method might fail. An alternative is to use PowerShell, which gives you additional possibilities, like ignoring case by using `ToLower()`:
+
+    ps: if($env:APPVEYOR_REPO_COMMIT_MESSAGE.ToLower().Contains('[publish binary]')) { node-pre-gyp --msvs_version=2013 publish }
+
+Remember this publishing is not the same as `npm publish`. We're just talking about the binary module here and not your entire npm package.
+
+## Travis Automation
+
+[Travis](https://travis-ci.org/) can push to S3 after a successful build and supports both:
+
+ - Ubuntu Precise and OS X (64 bit)
+ - Multiple Node.js versions
+
+For an example of doing this see [node-add-example's .travis.yml](https://github.com/springmeyer/node-addon-example/blob/2ff60a8ded7f042864ad21db00c3a5a06cf47075/.travis.yml).
+
+Note: if you need 32 bit binaries, this can be done from a 64 bit Travis machine. See [the node-sqlite3 scripts for an example of doing this](https://github.com/mapbox/node-sqlite3/blob/bae122aa6a2b8a45f6b717fab24e207740e32b5d/scripts/build_against_node.sh#L54-L74).
+
+Below is a guide to getting set up:
+
+#### 1) Install the Travis gem
+
+    gem install travis
+
+#### 2) Create secure variables
+
+Make sure you run this command from within the directory of your module.
+
+Use `travis-encrypt` like:
+
+    travis encrypt AWS_ACCESS_KEY_ID=${node_pre_gyp_accessKeyId}
+    travis encrypt AWS_SECRET_ACCESS_KEY=${node_pre_gyp_secretAccessKey}
+
+Then put those values in your `.travis.yml` like:
+
+```yaml
+env:
+  global:
+    - secure: F+sEL/v56CzHqmCSSES4pEyC9NeQlkoR0Gs/ZuZxX1ytrj8SKtp3MKqBj7zhIclSdXBz4Ev966Da5ctmcTd410p0b240MV6BVOkLUtkjZJyErMBOkeb8n8yVfSoeMx8RiIhBmIvEn+rlQq+bSFis61/JkE9rxsjkGRZi14hHr4M=
+    - secure: o2nkUQIiABD139XS6L8pxq3XO5gch27hvm/gOdV+dzNKc/s2KomVPWcOyXNxtJGhtecAkABzaW8KHDDi5QL1kNEFx6BxFVMLO8rjFPsMVaBG9Ks6JiDQkkmrGNcnVdxI/6EKTLHTH5WLsz8+J7caDBzvKbEfTux5EamEhxIWgrI=
+```
+
+More details on Travis encryption at http://about.travis-ci.org/docs/user/encryption-keys/.
+
+#### 3) Hook up publishing
+
+Just put `node-pre-gyp package publish` in your `.travis.yml` after `npm install`.
+
+##### OS X publishing
+
+If you want binaries for OS X in addition to linux you can enable [multi-os for Travis](http://docs.travis-ci.com/user/multi-os/#Setting-.travis.yml)
+
+Use a configuration like:
+
+```yml
+
+language: cpp
+
+os:
+- linux
+- osx
+
+env:
+  matrix:
+    - NODE_VERSION="4"
+    - NODE_VERSION="6"
+
+before_install:
+- rm -rf ~/.nvm/ && git clone --depth 1 https://github.com/creationix/nvm.git ~/.nvm
+- source ~/.nvm/nvm.sh
+- nvm install $NODE_VERSION
+- nvm use $NODE_VERSION
+```
+
+See [Travis OS X Gotchas](#travis-os-x-gotchas) for why we replace `language: node_js` and `node_js:` sections with `language: cpp` and a custom matrix.
+
+Also create platform specific sections for any deps that need install. For example if you need libpng:
+
+```yml
+- if [ $(uname -s) == 'Linux' ]; then apt-get install libpng-dev; fi;
+- if [ $(uname -s) == 'Darwin' ]; then brew install libpng; fi;
+```
+
+For detailed multi-OS examples see [node-mapnik](https://github.com/mapnik/node-mapnik/blob/master/.travis.yml) and [node-sqlite3](https://github.com/mapbox/node-sqlite3/blob/master/.travis.yml).
+
+##### Travis OS X Gotchas
+
+First, unlike the Travis Linux machines, the OS X machines do not put `node-pre-gyp` on PATH by default. To do so you will need to:
+
+```sh
+export PATH=$(pwd)/node_modules/.bin:${PATH}
+```
+
+Second, the OS X machines do not support using a matrix for installing different Node.js versions. So you need to bootstrap the installation of Node.js in a cross platform way.
+
+By doing:
+
+```yml
+env:
+  matrix:
+    - NODE_VERSION="4"
+    - NODE_VERSION="6"
+
+before_install:
+ - rm -rf ~/.nvm/ && git clone --depth 1 https://github.com/creationix/nvm.git ~/.nvm
+ - source ~/.nvm/nvm.sh
+ - nvm install $NODE_VERSION
+ - nvm use $NODE_VERSION
+```
+
+You can easily recreate the previous behavior of this matrix:
+
+```yml
+node_js:
+  - "4"
+  - "6"
+```
+
+#### 4) Publish when you want
+
+You might wish to publish binaries only on a specific commit. To do this you could borrow from the [Travis CI idea of commit keywords](http://about.travis-ci.org/docs/user/how-to-skip-a-build/) and add special handling for commit messages with `[publish binary]`:
+
+    COMMIT_MESSAGE=$(git log --format=%B --no-merges -n 1 | tr -d '\n')
+    if [[ ${COMMIT_MESSAGE} =~ "[publish binary]" ]]; then node-pre-gyp publish; fi;
+
+Then you can trigger new binaries to be built like:
+
+    git commit -a -m "[publish binary]"
+
+Or, if you don't have any changes to make simply run:
+
+    git commit --allow-empty -m "[publish binary]"
+
+WARNING: if you are working in a pull request and publishing binaries from there then you will want to avoid double publishing when Travis CI builds both the `push` and `pr`. You only want to run the publish on the `push` commit. See https://github.com/Project-OSRM/node-osrm/blob/8eb837abe2e2e30e595093d16e5354bc5c573575/scripts/is_pr_merge.sh which is called from https://github.com/Project-OSRM/node-osrm/blob/8eb837abe2e2e30e595093d16e5354bc5c573575/scripts/publish.sh for an example of how to do this.
+
+Remember this publishing is not the same as `npm publish`. We're just talking about the binary module here and not your entire npm package. To automate the publishing of your entire package to npm on Travis see http://about.travis-ci.org/docs/user/deployment/npm/
+
+# Versioning
+
+The `binary` properties of `module_path`, `remote_path`, and `package_name` support variable substitution. The strings are evaluated by `node-pre-gyp` depending on your system and any custom build flags you passed.
+
+ - `node_abi`: The node C++ `ABI` number. This value is available in Javascript as `process.versions.modules` as of [`>= v0.10.4 >= v0.11.7`](https://github.com/joyent/node/commit/ccabd4a6fa8a6eb79d29bc3bbe9fe2b6531c2d8e) and in C++ as the `NODE_MODULE_VERSION` define much earlier. For versions of Node before this was available we fallback to the V8 major and minor version.
+ - `platform` matches node's `process.platform` like `linux`, `darwin`, and `win32` unless the user passed the `--target_platform` option to override.
+ - `arch` matches node's `process.arch` like `x64` or `ia32` unless the user passes the `--target_arch` option to override.
+ - `libc` matches `require('detect-libc').family` like `glibc` or `musl` unless the user passes the `--target_libc` option to override.
+ - `configuration` - Either 'Release' or 'Debug' depending on if `--debug` is passed during the build.
+ - `module_name` - the `binary.module_name` attribute from `package.json`.
+ - `version` - the semver `version` value for your module from `package.json` (NOTE: ignores the `semver.build` property).
+ - `major`, `minor`, `patch`, and `prelease` match the individual semver values for your module's `version`
+ - `build` - the sevmer `build` value. For example it would be `this.that` if your package.json `version` was `v1.0.0+this.that`
+ - `prerelease` - the semver `prerelease` value. For example it would be `alpha.beta` if your package.json `version` was `v1.0.0-alpha.beta`
+
+
+The options are visible in the code at <https://github.com/mapbox/node-pre-gyp/blob/612b7bca2604508d881e1187614870ba19a7f0c5/lib/util/versioning.js#L114-L127>
+
+# Download binary files from a mirror
+
+S3 is broken in China for the well known reason.
+
+Using the `npm` config argument: `--{module_name}_binary_host_mirror` can download binary files through a mirror, `-` in `module_name` will be replaced with `_`.
+
+e.g.: Install [v8-profiler](https://www.npmjs.com/package/v8-profiler) from `npm`.
+
+```bash
+$ npm install v8-profiler --profiler_binary_host_mirror=https://npm.taobao.org/mirrors/node-inspector/
+```
+
+e.g.: Install [canvas-prebuilt](https://www.npmjs.com/package/canvas-prebuilt) from `npm`.
+
+```bash
+$ npm install canvas-prebuilt --canvas_prebuilt_binary_host_mirror=https://npm.taobao.org/mirrors/canvas-prebuilt/

+
+Here we gather node-pre-gyp generated options (from versioning) and pass them along to node-gyp.
+
+We massage the args and options slightly to account for differences in what commands mean between
+node-pre-gyp and node-gyp (e.g. see the difference between "build" and "rebuild" below)
+
+Keep in mind: the values inside `argv` and `gyp.opts` below are different depending on whether
+node-pre-gyp is called directory, or if it is called in a `run-script` phase of npm.
+
+We also try to preserve any command line options that might have been passed to npm or node-pre-gyp.
+But this is fairly difficult without passing way to much through. For example `gyp.opts` contains all
+the process.env and npm pushes a lot of variables into process.env which node-pre-gyp inherits. So we have
+to be very selective about what we pass through.
+
+For example:
+
+`npm install --build-from-source` will give:
+
+argv == [ 'rebuild' ]
+gyp.opts.argv == { remain: [ 'install' ],
+  cooked: [ 'install', '--fallback-to-build' ],
+  original: [ 'install', '--fallback-to-build' ] }

+argv == []

+                    The below code tries to infer the last known ABI compatible version
+                    that we have recorded in the abi_crosswalk.json when an exact match
+                    is not possible. The reasons for this to exist are complicated:
+
+                       - We support passing --target to be able to allow developers to package binaries for versions of node
+                         that are not the same one as they are running. This might also be used in combination with the
+                         --target_arch or --target_platform flags to also package binaries for alternative platforms
+                       - When --target is passed we can't therefore determine the ABI (process.versions.modules) from the node
+                         version that is running in memory
+                       - So, therefore node-pre-gyp keeps an "ABI crosswalk" (lib/util/abi_crosswalk.json) to be able to look
+                         this info up for all versions
+                       - But we cannot easily predict what the future ABI will be for released versions
+                       - And node-pre-gyp needs to be a `bundledDependency` in apps that depend on it in order to work correctly
+                         by being fully available at install time.
+                       - So, the speed of node releases and the bundled nature of node-pre-gyp mean that a new node-pre-gyp release
+                         need to happen for every node.js/io.js/node-webkit/nw.js/atom-shell/etc release that might come online if
+                         you want the `--target` flag to keep working for the latest version
+                       - Which is impractical ^^
+                       - Hence the below code guesses about future ABI to make the need to update node-pre-gyp less demanding.
+
+                    In practice then you can have a dependency of your app like `node-sqlite3` that bundles a `node-pre-gyp` that
+                    only knows about node v0.10.33 in the `abi_crosswalk.json` but target node v0.10.34 (which is assumed to be
+                    ABI compatible with v0.10.33).

+are-we-there-yet
+----------------
+
+Track complex hierarchies of asynchronous task completion statuses.  This is
+intended to give you a way of recording and reporting the progress of the big
+recursive fan-out and gather type workflows that are so common in async.
+
+What you do with this completion data is up to you, but the most common use case is to
+feed it to one of the many progress bar modules.
+
+Most progress bar modules include a rudimentary version of this, but my
+needs were more complex.
+
+Usage
+=====
+
+```javascript
+var TrackerGroup = require("are-we-there-yet").TrackerGroup
+
+var top = new TrackerGroup("program")
+
+var single = top.newItem("one thing", 100)
+single.completeWork(20)
+
+console.log(top.completed()) // 0.2
+
+fs.stat("file", function(er, stat) {
+  if (er) throw er  
+  var stream = top.newStream("file", stat.size)
+  console.log(top.completed()) // now 0.1 as single is 50% of the job and is 20% complete
+                              // and 50% * 20% == 10%
+  fs.createReadStream("file").pipe(stream).on("data", function (chunk) {
+    // do stuff with chunk
+  })
+  top.on("change", function (name) {
+    // called each time a chunk is read from "file"
+    // top.completed() will start at 0.1 and fill up to 0.6 as the file is read
+  })
+})
+```
+
+Shared Methods
+==============
+
+* var completed = tracker.completed()
+
+Implemented in: `Tracker`, `TrackerGroup`, `TrackerStream`
+
+Returns the ratio of completed work to work to be done. Range of 0 to 1.
+
+* tracker.finish()
+
+Implemented in: `Tracker`, `TrackerGroup`
+
+Marks the tracker as completed. With a TrackerGroup this marks all of its
+components as completed.
+
+Marks all of the components of this tracker as finished, which in turn means
+that `tracker.completed()` for this will now be 1.
+
+This will result in one or more `change` events being emitted.

+All tracker objects emit `change` events with the following arguments:
+
+```
+function (name, completed, tracker)
+```
+
+`name` is the name of the tracker that originally emitted the event,
+or if it didn't have one, the first containing tracker group that had one.
+
+`completed` is the percent complete (as returned by `tracker.completed()` method).
+
+`tracker` is the tracker object that you are listening for events on.
+
+TrackerGroup
+============
+
+* var tracker = new TrackerGroup(**name**)
+
+  * **name** *(optional)* - The name of this tracker group, used in change
+    notifications if the component updating didn't have a name. Defaults to undefined.
+
+Creates a new empty tracker aggregation group. These are trackers whose
+completion status is determined by the completion status of other trackers added to this aggregation group.
+
+Ex.
+
+```javascript
+var tracker = new TrackerGroup("parent")
+var foo = tracker.newItem("firstChild", 100)
+var bar = tracker.newItem("secondChild", 100)
+
+foo.finish()
+console.log(tracker.completed()) // 0.5
+bar.finish()
+console.log(tracker.completed()) // 1
+```
+
+* tracker.addUnit(**otherTracker**, **weight**)
+
+  * **otherTracker** - Any of the other are-we-there-yet tracker objects
+  * **weight** *(optional)* - The weight to give the tracker, defaults to 1.
+
+Adds the **otherTracker** to this aggregation group. The weight determines
+how long you expect this tracker to take to complete in proportion to other
+units.  So for instance, if you add one tracker with a weight of 1 and
+another with a weight of 2, you're saying the second will take twice as long
+to complete as the first.  As such, the first will account for 33% of the
+completion of this tracker and the second will account for the other 67%.
+
+Returns **otherTracker**.
+
+* var subGroup = tracker.newGroup(**name**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+  var subGroup = tracker.addUnit(new TrackerGroup(name), weight)
+```
+
+* var subItem = tracker.newItem(**name**, **todo**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+  var subItem = tracker.addUnit(new Tracker(name, todo), weight)
+```
+
+* var subStream = tracker.newStream(**name**, **todo**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+  var subStream = tracker.addUnit(new TrackerStream(name, todo), weight)
+```
+
+* console.log( tracker.debug() )
+
+Returns a tree showing the completion of this tracker group and all of its
+children, including recursively entering all of the children.
+
+Tracker
+=======
+
+* var tracker = new Tracker(**name**, **todo**)
+
+  * **name** *(optional)* The name of this counter to report in change
+    events.  Defaults to undefined.
+  * **todo** *(optional)* The amount of work todo (a number). Defaults to 0.
+
+Ordinarily these are constructed as a part of a tracker group (via
+`newItem`).
+
+* var completed = tracker.completed()
+
+Returns the ratio of completed work to work to be done. Range of 0 to 1. If
+total work to be done is 0 then it will return 0.
+
+* tracker.addWork(**todo**)
+
+  * **todo** A number to add to the amount of work to be done.
+
+Increases the amount of work to be done, thus decreasing the completion
+percentage.  Triggers a `change` event.
+
+* tracker.completeWork(**completed**)
+
+  * **completed** A number to add to the work complete
+
+Increase the amount of work complete, thus increasing the completion percentage.
+Will never increase the work completed past the amount of work todo. That is,
+percentages > 100% are not allowed. Triggers a `change` event.
+
+* tracker.finish()
+
+Marks this tracker as finished, tracker.completed() will now be 1. Triggers
+a `change` event.
+
+TrackerStream
+=============
+
+* var tracker = new TrackerStream(**name**, **size**, **options**)
+
+  * **name** *(optional)* The name of this counter to report in change
+    events.  Defaults to undefined.
+  * **size** *(optional)* The number of bytes being sent through this stream.
+  * **options** *(optional)* A hash of stream options
+
+The tracker stream object is a pass through stream that updates an internal
+tracker object each time a block passes through.  It's intended to track
+downloads, file extraction and other related activities. You use it by piping
+your data source into it and then using it as your data source.
+
+If your data has a length attribute then that's used as the amount of work
+completed when the chunk is passed through.  If it does not (eg, object
+streams) then each chunk counts as completing 1 unit of work, so your size
+should be the total number of objects being streamed.
+
+* tracker.addWork(**todo**)
+
+  * **todo** Increase the expected overall size by **todo** bytes.
+
+Increases the amount of work to be done, thus decreasing the completion
+percentage.  Triggers a `change` event.

@@ -0,0 +1,163 @@
+### v3.0.0
+* Drops support for Node v4, v6, v7 and v8
+
+### v2.7.4
+
+* Reset colors prior to ending a line, to eliminate flicker when a line
+  is trucated between start and end color sequences.
+
+### v2.7.3
+
+* Only create our onExit handler when we're enabled and remove it when we're
+  disabled.  This stops us from creating multiple onExit handlers when
+  multiple gauge objects are being used.
+* Fix bug where if a theme name were given instead of a theme object, it
+  would crash.
+* Remove supports-color because it's not actually used.  Uhm.  Yes, I just
+  updated it.  >.>
+
+### v2.7.2
+
+* Use supports-color instead of has-color (as the module has been renamed)
+
+### v2.7.1
+
+* Bug fix: Calls to show/pulse while the progress bar is disabled should still
+  update our internal representation of what would be shown should it be enabled.
+
+### v2.7.0
+
+* New feature: Add new `isEnabled` method to allow introspection of the gauge's
+  "enabledness" as controlled by `.enable()` and `.disable()`.
+
+### v2.6.0
+
+* Bug fix: Don't run the code associated with `enable`/`disable` if the gauge
+  is already enabled or disabled respectively.  This prevents leaking event
+  listeners, amongst other weirdness.
+* New feature: Template items can have default values that will be used if no
+  value was otherwise passed in.
+
+### v2.5.3
+
+* Default to `enabled` only if we have a tty.  Users can always override
+  this by passing in the `enabled` option explicitly or by calling calling
+  `gauge.enable()`.
+
+### v2.5.2
+
+* Externalized `./console-strings.js` into `console-control-strings`.
+
+### v2.5.1
+
+* Update to `signal-exit@3.0.0`, which fixes a compatibility bug with the
+  node profiler.
+* [#39](https://github.com/iarna/gauge/pull/39) Fix tests on 0.10 and add
+  a missing devDependency. ([@helloyou2012](https://github.com/helloyou2012))
+
+### v2.5.0
+
+* Add way to programmatically fetch a list of theme names in a themeset
+  (`Themeset.getThemeNames`).
+
+### v2.4.0
+
+* Add support for setting themesets on existing gauge objects.
+* Add post-IO callback to `gauge.hide()` as it is somtetimes necessary when
+  your terminal is interleaving output from multiple filehandles (ie, stdout
+  & stderr).
+
+### v2.3.1
+
+* Fix a refactor bug in setTheme where it wasn't accepting the various types
+  of args it should.
+
+### v2.3.0
+
+#### FEATURES
+
+* Add setTemplate & setTheme back in.
+* Add support for named themes, you can now ask for things like 'colorASCII'
+  and 'brailleSpinner'.  Of course, you can still pass in theme objects.
+  Additionally you can now pass in an object with `hasUnicode`, `hasColor` and
+  `platform` keys in order to override our guesses as to those values when
+  selecting a default theme from the themeset.
+* Make the output stream optional (it defaults to `process.stderr` now).
+* Add `setWriteTo(stream[, tty])` to change the output stream and,
+  optionally, tty.
+
+#### BUG FIXES & REFACTORING
+
+* Abort the display phase early if we're supposed to be hidden and we are.
+* Stop printing a bunch of spaces at the end of lines, since we're already
+  using an erase-to-end-of-line code anyway.
+* The unicode themes were missing the subsection separator.
+
+### v2.2.1
+
+* Fix image in readme
+
+### v2.2.0
+
+* All new themes API– reference themes by name and pass in custom themes and
+  themesets (themesets get platform support autodetection done on them to
+  select the best theme).  Theme mixins let you add features to all existing
+  themes.
+* Much, much improved test coverage.
+
+### v2.1.0
+
+* Got rid of ░ in the default platform, noUnicode, hasColor theme.  Thanks
+  to @yongtw123 for pointing out this had snuck in.
+* Fiddled with the demo output to make it easier to see the spinner spin. Also
+  added prints before each platforms test output.
+* I forgot to include `signal-exit` in our deps.  <.< Thank you @KenanY for
+  finding this. Then I was lazy and made a new commit instead of using his
+  PR. Again, thank you for your patience @KenenY.
+* Drastically speed up travis testing.
+* Add a small javascript demo (demo.js) for showing off the various themes
+  (and testing them on diff platforms).
+* Change: The subsection separator from ⁄ and / (different chars) to >.
+* Fix crasher: A show or pulse without a label would cause the template renderer
+  to complain about a missing value.
+* New feature: Add the ability to disable the clean-up-on-exit behavior.
+  Not something I expect to be widely desirable, but important if you have
+  multiple distinct gauge instances in your app.
+* Use our own color support detection.
+  The `has-color` module proved too magic for my needs, making assumptions
+  as to which stream we write to and reading command line arguments.
+
+### v2.0.0
+
+This is a major rewrite of the internals.  Externally there are fewer
+changes:
+
+* On node>0.8 gauge object now prints updates at a fixed rate.  This means
+  that when you call `show` it may wate up to `updateInterval` ms before it
+  actually prints an update.  You override this behavior with the
+  `fixedFramerate` option.
+* The gauge object now keeps the cursor hidden as long as it's enabled and
+  shown.
+* The constructor's arguments have changed, now it takes a mandatory output
+  stream and an optional options object.  The stream no longer needs to be
+  an `ansi`ified stream, although it can be if you want (but we won't make
+  use of its special features).
+* Previously the gauge was disabled by default if `process.stdout` wasn't a
+  tty.  Now it always defaults to enabled.  If you want the previous
+  behavior set the `enabled` option to `process.stdout.isTTY`.
+* The constructor's options have changed– see the docs for details.
+* Themes are entirely different.  If you were using a custom theme, or
+  referring to one directly (eg via `Gauge.unicode` or `Gauge.ascii`) then
+  you'll need to change your code.  You can get the equivalent of the latter
+  with:
+  ```
+  var themes = require('gauge/themes')
+  var unicodeTheme = themes(true, true) // returns the color unicode theme for your platform
+  ```
+  The default themes no longer use any ambiguous width characters, so even
+  if you choose to display those as wide your progress bar should still
+  display correctly.
+* Templates are entirely different and if you were using a custom one, you
+  should consult the documentation to learn how to recreate it.  If you were
+  using the default, be aware that it has changed and the result looks quite
+  a bit different.

+### CHANGES FROM 1.x
+
+Gauge 2.x is breaking release, please see the [changelog] for details on
+what's changed if you were previously a user of this module.
+
+[changelog]: CHANGELOG.md
+
+### THE GAUGE CLASS
+
+This is the typical interface to the module– it provides a pretty
+fire-and-forget interface to displaying your status information.
+
+```
+var Gauge = require("gauge")
+
+var gauge = new Gauge([stream], [options])
+```
+
+* **stream** – *(optional, default STDERR)* A stream that progress bar
+  updates are to be written to.  Gauge honors backpressure and will pause
+  most writing if it is indicated.
+* **options** – *(optional)* An option object.
+
+Constructs a new gauge. Gauges are drawn on a single line, and are not drawn
+if **stream** isn't a tty and a tty isn't explicitly provided.
+
+If **stream** is a terminal or if you pass in **tty** to **options** then we
+will detect terminal resizes and redraw to fit.  We do this by watching for
+`resize` events on the tty.  (To work around a bug in versions of Node prior
+to 2.5.0, we watch for them on stdout if the tty is stderr.) Resizes to
+larger window sizes will be clean, but shrinking the window will always
+result in some cruft.
+
+**IMPORTANT:** If you previously were passing in a non-tty stream but you still
+want output (for example, a stream wrapped by the `ansi` module) then you
+need to pass in the **tty** option below, as `gauge` needs access to
+the underlying tty in order to do things like terminal resizes and terminal
+width detection.
+
+The **options** object can have the following properties, all of which are
+optional:
+
+* **updateInterval**: How often gauge updates should be drawn, in milliseconds.
+* **fixedFramerate**: Defaults to false on node 0.8, true on everything
+  else.  When this is true a timer is created to trigger once every
+  `updateInterval` ms, when false, updates are printed as soon as they come
+  in but updates more often than `updateInterval` are ignored.  The reason
+  0.8 doesn't have this set to true is that it can't `unref` its timer and
+  so it would stop your program from exiting– if you want to use this
+  feature with 0.8 just make sure you call `gauge.disable()` before you
+  expect your program to exit.
+* **themes**: A themeset to use when selecting the theme to use. Defaults
+  to `gauge/themes`, see the [themes] documentation for details.
+* **theme**: Select a theme for use, it can be a:
+  * Theme object, in which case the **themes** is not used.
+  * The name of a theme, which will be looked up in the current *themes*
+    object.
+  * A configuration object with any of `hasUnicode`, `hasColor` or
+    `platform` keys, which if will be used to override our guesses when making
+    a default theme selection.
+
+  If no theme is selected then a default is picked using a combination of our
+  best guesses at your OS, color support and unicode support.
+* **template**: Describes what you want your gauge to look like.  The
+  default is what npm uses.  Detailed [documentation] is later in this
+  document.
+* **hideCursor**: Defaults to true.  If true, then the cursor will be hidden
+  while the gauge is displayed.
+* **tty**: The tty that you're ultimately writing to.  Defaults to the same
+  as **stream**.  This is used for detecting the width of the terminal and
+  resizes. The width used is `tty.columns - 1`. If no tty is available then
+  a width of `79` is assumed.
+* **enabled**: Defaults to true if `tty` is a TTY, false otherwise.  If true
+  the gauge starts enabled.  If disabled then all update commands are
+  ignored and no gauge will be printed until you call `.enable()`.
+* **Plumbing**: The class to use to actually generate the gauge for
+  printing.  This defaults to `require('gauge/plumbing')` and ordinarily you
+  shouldn't need to override this.
+* **cleanupOnExit**: Defaults to true. Ordinarily we register an exit
+  handler to make sure your cursor is turned back on and the progress bar
+  erased when your process exits, even if you Ctrl-C out or otherwise exit
+  unexpectedly. You can disable this and it won't register the exit handler.

+
+#### `gauge.show(section | status, [completed])`
+
+The first argument is either the section, the name of the current thing
+contributing to progress, or an object with keys like **section**,
+**subsection** & **completed** (or any others you have types for in a custom
+template).  If you don't want to update or set any of these you can pass
+`null` and it will be ignored.
+
+The second argument is the percent completed as a value between 0 and 1.
+Without it, completion is just not updated. You'll also note that completion
+can be passed in as part of a status object as the first argument. If both
+it and the completed argument are passed in, the completed argument wins.
+
+#### `gauge.hide([cb])`
+
+Removes the gauge from the terminal.  Optionally, callback `cb` after IO has
+had an opportunity to happen (currently this just means after `setImmediate`
+has called back.)
+
+It turns out this is important when you're pausing the progress bar on one
+filehandle and printing to another– otherwise (with a big enough print) node
+can end up printing the "end progress bar" bits to the progress bar filehandle
+while other stuff is printing to another filehandle. These getting interleaved
+can cause corruption in some terminals.
+
+#### `gauge.pulse([subsection])`
+
+* **subsection** – *(optional)* The specific thing that triggered this pulse
+
+Spins the spinner in the gauge to show output.  If **subsection** is
+included then it will be combined with the last name passed to `gauge.show`.
+
+#### `gauge.disable()`
+
+Hides the gauge and ignores further calls to `show` or `pulse`.
+
+#### `gauge.enable()`
+
+Shows the gauge and resumes updating when `show` or `pulse` is called.
+
+#### `gauge.isEnabled()`
+
+Returns true if the gauge is enabled.
+
+#### `gauge.setThemeset(themes)`
+
+Change the themeset to select a theme from. The same as the `themes` option
+used in the constructor. The theme will be reselected from this themeset.
+
+#### `gauge.setTheme(theme)`
+
+Change the active theme, will be displayed with the next show or pulse. This can be:
+
+* Theme object, in which case the **themes** is not used.
+* The name of a theme, which will be looked up in the current *themes*
+  object.
+* A configuration object with any of `hasUnicode`, `hasColor` or
+  `platform` keys, which if will be used to override our guesses when making
+  a default theme selection.
+
+If no theme is selected then a default is picked using a combination of our
+best guesses at your OS, color support and unicode support.
+
+#### `gauge.setTemplate(template)`
+
+Change the active template, will be displayed with the next show or pulse
+
+### Tracking Completion
+
+If you have more than one thing going on that you want to track completion
+of, you may find the related [are-we-there-yet] helpful.  It's `change`
+event can be wired up to the `show` method to get a more traditional
+progress bar interface.

+
+### THEMES
+
+```
+var themes = require('gauge/themes')
+
+// fetch the default color unicode theme for this platform
+var ourTheme = themes({hasUnicode: true, hasColor: true})
+
+// fetch the default non-color unicode theme for osx
+var ourTheme = themes({hasUnicode: true, hasColor: false, platform: 'darwin'})
+
+// create a new theme based on the color ascii theme for this platform
+// that brackets the progress bar with arrows
+var ourTheme = themes.newTheme(themes({hasUnicode: false, hasColor: true}), {
+  preProgressbar: '→',
+  postProgressbar: '←'
+})
+```
+
+The object returned by `gauge/themes` is an instance of the `ThemeSet` class.
+
+```
+var ThemeSet = require('gauge/theme-set')
+var themes = new ThemeSet()
+// or
+var themes = require('gauge/themes')
+var mythemes = themes.newThemeSet() // creates a new themeset based on the default themes
+```
+
+#### themes(opts)
+#### themes.getDefault(opts)
+
+Theme objects are a function that fetches the default theme based on
+platform, unicode and color support.
+
+Options is an object with the following properties:
+
+* **hasUnicode** - If true, fetch a unicode theme, if no unicode theme is
+  available then a non-unicode theme will be used.
+* **hasColor** - If true, fetch a color theme, if no color theme is
+  available a non-color theme will be used.
+* **platform** (optional) - Defaults to `process.platform`.  If no
+  platform match is available then `fallback` is used instead.
+
+If no compatible theme can be found then an error will be thrown with a
+`code` of `EMISSINGTHEME`.
+
+#### themes.addTheme(themeName, themeObj)
+#### themes.addTheme(themeName, [parentTheme], newTheme)
+
+Adds a named theme to the themeset.  You can pass in either a theme object,
+as returned by `themes.newTheme` or the arguments you'd pass to
+`themes.newTheme`.
+
+#### themes.getThemeNames()
+
+Return a list of all of the names of the themes in this themeset. Suitable
+for use in `themes.getTheme(…)`.
+
+#### themes.getTheme(name)
+
+Returns the theme object from this theme set named `name`.
+
+If `name` does not exist in this themeset an error will be thrown with
+a `code` of `EMISSINGTHEME`.
+
+#### themes.setDefault([opts], themeName)
+
+`opts` is an object with the following properties.
+
+* **platform** - Defaults to `'fallback'`.  If your theme is platform
+  specific, specify that here with the platform from `process.platform`, eg,
+  `win32`, `darwin`, etc.
+* **hasUnicode** - Defaults to `false`. If your theme uses unicode you
+  should set this to true.
+* **hasColor** - Defaults to `false`.  If your theme uses color you should
+  set this to true.
+
+`themeName` is the name of the theme (as given to `addTheme`) to use for
+this set of `opts`.
+
+#### themes.newTheme([parentTheme,] newTheme)
+
+Create a new theme object based on `parentTheme`.  If no `parentTheme` is
+provided then a minimal parentTheme that defines functions for rendering the
+activity indicator (spinner) and progress bar will be defined. (This
+fallback parent is defined in `gauge/base-theme`.)
+
+newTheme should be a bare object– we'll start by discussing the properties
+defined by the default themes:
+
+* **preProgressbar** - displayed prior to the progress bar, if the progress
+  bar is displayed.
+* **postProgressbar** - displayed after the progress bar, if the progress bar
+  is displayed.
+* **progressBarTheme** - The subtheme passed through to the progress bar
+  renderer, it's an object with `complete` and `remaining` properties
+  that are the strings you want repeated for those sections of the progress
+  bar.
+* **activityIndicatorTheme** - The theme for the activity indicator (spinner),
+  this can either be a string, in which each character is a different step, or
+  an array of strings.
+* **preSubsection** - Displayed as a separator between the `section` and
+  `subsection` when the latter is printed.
+
+More generally, themes can have any value that would be a valid value when rendering
+templates. The properties in the theme are used when their name matches a type in
+the template. Their values can be:
+
+* **strings & numbers** - They'll be included as is
+* **function (values, theme, width)** - Should return what you want in your output.
+  *values* is an object with values provided via `gauge.show`,
+  *theme* is the theme specific to this item (see below) or this theme object,
+  and *width* is the number of characters wide your result should be.
+
+There are a couple of special prefixes:
+
+* **pre** - Is shown prior to the property, if its displayed.
+* **post** - Is shown after the property, if its displayed.
+
+And one special suffix:
+
+* **Theme** - Its value is passed to a function-type item as the theme.
+
+#### themes.addToAllThemes(theme)
+
+This *mixes-in* `theme` into all themes currently defined. It also adds it
+to the default parent theme for this themeset, so future themes added to
+this themeset will get the values from `theme` by default.
+
+#### themes.newThemeSet()
+
+Copy the current themeset into a new one.  This allows you to easily inherit
+one themeset from another.
+
+### TEMPLATES
+
+A template is an array of objects and strings that, after being evaluated,
+will be turned into the gauge line.  The default template is:
+
+```javascript
+[
+    {type: 'progressbar', length: 20},
+    {type: 'activityIndicator', kerning: 1, length: 1},
+    {type: 'section', kerning: 1, default: ''},
+    {type: 'subsection', kerning: 1, default: ''}
+]
+```
+
+The various template elements can either be **plain strings**, in which case they will
+be be included verbatum in the output, or objects with the following properties:
+
+* *type* can be any of the following plus any keys you pass into `gauge.show` plus
+  any keys you have on a custom theme.
+  * `section` – What big thing you're working on now.
+  * `subsection` – What component of that thing is currently working.
+  * `activityIndicator` – Shows a spinner using the `activityIndicatorTheme`
+    from your active theme.
+  * `progressbar` – A progress bar representing your current `completed`
+    using the `progressbarTheme` from your active theme.
+* *kerning* – Number of spaces that must be between this item and other
+  items, if this item is displayed at all.
+* *maxLength* – The maximum length for this element. If its value is longer it
+  will be truncated.
+* *minLength* – The minimum length for this element. If its value is shorter it
+  will be padded according to the *align* value.
+* *align* – (Default: left) Possible values "left", "right" and "center". Works
+  as you'd expect from word processors.
+* *length* – Provides a single value for both *minLength* and *maxLength*. If both
+  *length* and *minLength or *maxLength* are specified then the latter take precedence.
+* *value* – A literal value to use for this template item.
+* *default* – A default value to use for this template item if a value
+  wasn't otherwise passed in.
+
+### PLUMBING
+
+This is the super simple, assume nothing, do no magic internals used by gauge to
+implement its ordinary interface.
+
+```
+var Plumbing = require('gauge/plumbing')
+var gauge = new Plumbing(theme, template, width)
+```
+
+* **theme**: The theme to use.
+* **template**: The template to use.
+* **width**: How wide your gauge should be
+
+#### `gauge.setTheme(theme)`
+
+Change the active theme.
+
+#### `gauge.setTemplate(template)`
+
+Change the active template.
+
+#### `gauge.setWidth(width)`
+
+Change the width to render at.
+
+#### `gauge.hide()`
+
+Return the string necessary to hide the progress bar
+
+#### `gauge.hideCursor()`
+
+Return a string to hide the cursor.
+
+#### `gauge.showCursor()`
+
+Return a string to show the cursor.
+
+#### `gauge.show(status)`
+
+Using `status` for values, render the provided template with the theme and return
+a string that is suitable for printing to update the gauge.

+# npmlog
+
+The logger util that npm uses.
+
+This logger is very basic.  It does the logging for npm.  It supports
+custom levels and colored output.
+
+By default, logs are written to stderr.  If you want to send log messages
+to outputs other than streams, then you can change the `log.stream`
+member, or you can just listen to the events that it emits, and do
+whatever you want with them.
+
+# Installation
+
+```console
+npm install npmlog --save
+```
+
+# Basic Usage
+
+```javascript
+var log = require('npmlog')
+
+// additional stuff ---------------------------+
+// message ----------+                         |
+// prefix ----+      |                         |
+// level -+   |      |                         |
+//        v   v      v                         v
+    log.info('fyi', 'I have a kitty cat: %j', myKittyCat)
+```
+
+## log.level
+
+* {String}
+
+The level to display logs at.  Any logs at or above this level will be
+displayed.  The special level `silent` will prevent anything from being
+displayed ever.
+
+## log.record
+
+* {Array}
+
+An array of all the log messages that have been entered.
+
+## log.maxRecordSize
+
+* {Number}
+
+The maximum number of records to keep.  If log.record gets bigger than
+10% over this value, then it is sliced down to 90% of this value.
+
+The reason for the 10% window is so that it doesn't have to resize a
+large array on every log entry.
+
+## log.prefixStyle
+
+* {Object}
+
+A style object that specifies how prefixes are styled.  (See below)
+
+## log.headingStyle
+
+* {Object}
+
+A style object that specifies how the heading is styled.  (See below)
+
+## log.heading
+
+* {String} Default: ""
+
+If set, a heading that is printed at the start of every line.
+
+## log.stream
+
+* {Stream} Default: `process.stderr`
+
+The stream where output is written.
+
+## log.enableColor()
+
+Force colors to be used on all messages, regardless of the output
+stream.
+
+## log.disableColor()
+
+Disable colors on all messages.
+
+## log.enableProgress()
+
+Enable the display of log activity spinner and progress bar
+
+## log.disableProgress()
+
+Disable the display of a progress bar
+
+## log.enableUnicode()
+
+Force the unicode theme to be used for the progress bar.
+
+## log.disableUnicode()
+
+Disable the use of unicode in the progress bar.
+
+## log.setGaugeTemplate(template)
+
+Set a template for outputting the progress bar. See the [gauge documentation] for details.
+
+[gauge documentation]: https://npmjs.com/package/gauge
+
+## log.setGaugeThemeset(themes)
+
+Select a themeset to pick themes from for the progress bar. See the [gauge documentation] for details.
+
+## log.pause()
+
+Stop emitting messages to the stream, but do not drop them.
+
+## log.resume()
+
+Emit all buffered messages that were written while paused.
+
+## log.log(level, prefix, message, ...)
+
+* `level` {String} The level to emit the message at
+* `prefix` {String} A string prefix.  Set to "" to skip.
+* `message...` Arguments to `util.format`
+
+Emit a log message at the specified level.
+
+## log\[level](prefix, message, ...)
+
+For example,
+
+* log.silly(prefix, message, ...)
+* log.verbose(prefix, message, ...)
+* log.info(prefix, message, ...)
+* log.http(prefix, message, ...)
+* log.warn(prefix, message, ...)
+* log.error(prefix, message, ...)
+
+Like `log.log(level, prefix, message, ...)`.  In this way, each level is
+given a shorthand, so you can do `log.info(prefix, message)`.
+
+## log.addLevel(level, n, style, disp)
+
+* `level` {String} Level indicator
+* `n` {Number} The numeric level
+* `style` {Object} Object with fg, bg, inverse, etc.
+* `disp` {String} Optional replacement for `level` in the output.
+
+Sets up a new level with a shorthand function and so forth.
+
+Note that if the number is `Infinity`, then setting the level to that
+will cause all log messages to be suppressed.  If the number is
+`-Infinity`, then the only way to show it is to enable all log messages.
+
+## log.newItem(name, todo, weight)
+
+* `name` {String} Optional; progress item name.
+* `todo` {Number} Optional; total amount of work to be done. Default 0.
+* `weight` {Number} Optional; the weight of this item relative to others. Default 1.
+
+This adds a new `are-we-there-yet` item tracker to the progress tracker. The
+object returned has the `log[level]` methods but is otherwise an
+`are-we-there-yet` `Tracker` object.
+
+## log.newStream(name, todo, weight)
+
+This adds a new `are-we-there-yet` stream tracker to the progress tracker. The
+object returned has the `log[level]` methods but is otherwise an
+`are-we-there-yet` `TrackerStream` object.
+
+## log.newGroup(name, weight)
+
+This adds a new `are-we-there-yet` tracker group to the progress tracker. The
+object returned has the `log[level]` methods but is otherwise an
+`are-we-there-yet` `TrackerGroup` object.
+
+# Events
+
+Events are all emitted with the message object.
+
+* `log` Emitted for all messages
+* `log.<level>` Emitted for all messages with the `<level>` level.
+* `<prefix>` Messages with prefixes also emit their prefix as an event.
+
+# Style Objects
+
+Style objects can have the following fields:
+
+* `fg` {String} Color for the foreground text
+* `bg` {String} Color for the background
+* `bold`, `inverse`, `underline` {Boolean} Set the associated property
+* `bell` {Boolean} Make a noise (This is pretty annoying, probably.)
+
+# Message Objects
+
+Every log event is emitted with a message object, and the `log.record`
+list contains all of them that have been created.  They have the
+following fields:
+
+* `id` {Number}
+* `level` {String}
+* `prefix` {String}
+* `message` {String} Result of `util.format()`
+* `messageRaw` {Array} Arguments to `util.format()`
+
+# Blocking TTYs
+
+We use [`set-blocking`](https://npmjs.com/package/set-blocking) to set
+stderr and stdout blocking if they are tty's and have the setBlocking call.
+This is a work around for an issue in early versions of Node.js 6.x, which
+made stderr and stdout non-blocking on OSX. (They are always blocking
+Windows and were never blocking on Linux.) `npmlog` needs them to be blocking
+so that it can allow output to stdout and stderr to be interlaced.

+# @npmcli/fs
+
+polyfills, and extensions, of the core `fs` module.
+
+## Features
+
+- all exposed functions return promises
+- `fs.rm` polyfill for node versions < 14.14.0
+- `fs.mkdir` polyfill adding support for the `recursive` and `force` options in node versions < 10.12.0
+- `fs.copyFile` extended to accept an `owner` option
+- `fs.mkdir` extended to accept an `owner` option
+- `fs.mkdtemp` extended to accept an `owner` option
+- `fs.writeFile` extended to accept an `owner` option
+- `fs.withTempDir` added
+- `fs.cp` polyfill for node < 16.7.0
+
+## The `owner` option
+
+The `copyFile`, `mkdir`, `mkdtemp`, `writeFile`, and `withTempDir` functions
+all accept a new `owner` property in their options. It can be used in two ways:
+
+- `{ owner: { uid: 100, gid: 100 } }` - set the `uid` and `gid` explicitly
+- `{ owner: 100 }` - use one value, will set both `uid` and `gid` the same
+
+The special string `'inherit'` may be passed instead of a number, which will
+cause this module to automatically determine the correct `uid` and/or `gid`
+from the nearest existing parent directory of the target.
+
+## `fs.withTempDir(root, fn, options) -> Promise`
+
+### Parameters
+
+- `root`: the directory in which to create the temporary directory
+- `fn`: a function that will be called with the path to the temporary directory
+- `options`
+  - `tmpPrefix`: a prefix to be used in the generated directory name
+
+### Usage
+
+The `withTempDir` function creates a temporary directory, runs the provided
+function (`fn`), then removes the temporary directory and resolves or rejects
+based on the result of `fn`.
+
+```js
+const fs = require('@npmcli/fs')
+const os = require('os')
+
+// this function will be called with the full path to the temporary directory
+// it is called with `await` behind the scenes, so can be async if desired.
+const myFunction = async (tempPath) => {
+  return 'done!'
+}
+
+const main = async () => {
+  const result = await fs.withTempDir(os.tmpdir(), myFunction)
+  // result === 'done!'
+}
+
+main()
+```
