+#Interface: DispatchInterceptor
+
+Extends: `Function`
+
+A function that can be applied to the `Dispatcher.Dispatch` function before it is invoked with a dispatch request.
+
+This allows one to write logic to intercept both the outgoing request, and the incoming response.
+
+### Parameter: `Dispatcher.Dispatch`
+
+The base dispatch function you are decorating.
+
+### ReturnType: `Dispatcher.Dispatch`
+
+A dispatch function that has been altered to provide additional logic
+
+### Basic Example
+
+Here is an example of an interceptor being used to provide a JWT bearer token
+
+```js
+'use strict'
+
+const insertHeaderInterceptor = dispatch => {
+  return function InterceptedDispatch(opts, handler){
+    opts.headers.push('Authorization', 'Bearer [Some token]')
+    return dispatch(opts, handler)
+  }
+}
+
+const client = new Client('https://localhost:3000', {
+  interceptors: { Client: [insertHeaderInterceptor] }
+})
+
+```
+
+### Basic Example 2
+
+Here is a contrived example of an interceptor stripping the headers from a response.
+
+```js
+'use strict'
+
+const clearHeadersInterceptor = dispatch => {
+  const { DecoratorHandler } = require('undici')
+  class ResultInterceptor extends DecoratorHandler {
+    onHeaders (statusCode, headers, resume) {
+      return super.onHeaders(statusCode, [], resume)
+    }
+  }
+  return function InterceptedDispatch(opts, handler){
+    return dispatch(opts, new ResultInterceptor(handler))
+  }
+}
+
+const client = new Client('https://localhost:3000', {
+  interceptors: { Client: [clearHeadersInterceptor] }
+})

+
+Changes (breaking or otherwise) in v1.0.0 can be found [here](https://github.com/mscdex/busboy/issues/266).
+
+# Requirements
+
+* [node.js](http://nodejs.org/) -- v10.16.0 or newer
+
+
+# Install
+
+    npm install busboy

+
+
+# API
+
+## Exports
+
+`busboy` exports a single function:
+
+**( _function_ )**(< _object_ >config) - Creates and returns a new _Writable_ form parser stream.
+
+* Valid `config` properties:
+
+    * **headers** - _object_ - These are the HTTP headers of the incoming request, which are used by individual parsers.
+
+    * **highWaterMark** - _integer_ - highWaterMark to use for the parser stream. **Default:** node's _stream.Writable_ default.
+
+    * **fileHwm** - _integer_ - highWaterMark to use for individual file streams. **Default:** node's _stream.Readable_ default.
+
+    * **defCharset** - _string_ - Default character set to use when one isn't defined. **Default:** `'utf8'`.
+
+    * **defParamCharset** - _string_ - For multipart forms, the default character set to use for values of part header parameters (e.g. filename) that are not extended parameters (that contain an explicit charset). **Default:** `'latin1'`.
+
+    * **preservePath** - _boolean_ - If paths in filenames from file parts in a `'multipart/form-data'` request shall be preserved. **Default:** `false`.
+
+    * **limits** - _object_ - Various limits on incoming data. Valid properties are:
+
+        * **fieldNameSize** - _integer_ - Max field name size (in bytes). **Default:** `100`.
+
+        * **fieldSize** - _integer_ - Max field value size (in bytes). **Default:** `1048576` (1MB).
+
+        * **fields** - _integer_ - Max number of non-file fields. **Default:** `Infinity`.
+
+        * **fileSize** - _integer_ - For multipart forms, the max file size (in bytes). **Default:** `Infinity`.
+
+        * **files** - _integer_ - For multipart forms, the max number of file fields. **Default:** `Infinity`.
+
+        * **parts** - _integer_ - For multipart forms, the max number of parts (fields + files). **Default:** `Infinity`.
+
+        * **headerPairs** - _integer_ - For multipart forms, the max number of header key-value pairs to parse. **Default:** `2000` (same as node's http module).
+
+This function can throw exceptions if there is something wrong with the values in `config`. For example, if the Content-Type in `headers` is missing entirely, is not a supported type, or is missing the boundary for `'multipart/form-data'` requests.
+
+## (Special) Parser stream events
+
+* **file**(< _string_ >name, < _Readable_ >stream, < _object_ >info) - Emitted for each new file found. `name` contains the form field name. `stream` is a _Readable_ stream containing the file's data. No transformations/conversions (e.g. base64 to raw binary) are done on the file's data. `info` contains the following properties:
+
+    * `filename` - _string_ - If supplied, this contains the file's filename. **WARNING:** You should almost _never_ use this value as-is (especially if you are using `preservePath: true` in your `config`) as it could contain malicious input. You are better off generating your own (safe) filenames, or at the very least using a hash of the filename.
+
+    * `encoding` - _string_ - The file's `'Content-Transfer-Encoding'` value.
+
+    * `mimeType` - _string_ - The file's `'Content-Type'` value.
+
+    **Note:** If you listen for this event, you should always consume the `stream` whether you care about its contents or not (you can simply do `stream.resume();` if you want to discard/skip the contents), otherwise the `'finish'`/`'close'` event will never fire on the busboy parser stream.
+    However, if you aren't accepting files, you can either simply not listen for the `'file'` event at all or set `limits.files` to `0`, and any/all files will be automatically skipped (these skipped files will still count towards any configured `limits.files` and `limits.parts` limits though).
+
+    **Note:** If a configured `limits.fileSize` limit was reached for a file, `stream` will both have a boolean property `truncated` set to `true` (best checked at the end of the stream) and emit a `'limit'` event to notify you when this happens.
+
+* **field**(< _string_ >name, < _string_ >value, < _object_ >info) - Emitted for each new non-file field found. `name` contains the form field name. `value` contains the string value of the field. `info` contains the following properties:
+
+    * `nameTruncated` - _boolean_ - Whether `name` was truncated or not (due to a configured `limits.fieldNameSize` limit)
+
+    * `valueTruncated` - _boolean_ - Whether `value` was truncated or not (due to a configured `limits.fieldSize` limit)
+
+    * `encoding` - _string_ - The field's `'Content-Transfer-Encoding'` value.
+
+    * `mimeType` - _string_ - The field's `'Content-Type'` value.
+

+Description
+===========
+
+streamsearch is a module for [node.js](http://nodejs.org/) that allows searching a stream using the Boyer-Moore-Horspool algorithm.
+
+This module is based heavily on the Streaming Boyer-Moore-Horspool C++ implementation by Hongli Lai [here](https://github.com/FooBarWidget/boyer-moore-horspool).
+
+
+Requirements
+============
+
+* [node.js](http://nodejs.org/) -- v10.0.0 or newer
+
+
+Installation
+============
+
+    npm install streamsearch
+
+Example
+=======
+
+```js
+  const { inspect } = require('util');
+
+  const StreamSearch = require('streamsearch');
+
+  const needle = Buffer.from('\r\n');
+  const ss = new StreamSearch(needle, (isMatch, data, start, end) => {
+    if (data)
+      console.log('data: ' + inspect(data.toString('latin1', start, end)));
+    if (isMatch)
+      console.log('match!');
+  });
+
+  const chunks = [
+    'foo',
+    ' bar',
+    '\r',
+    '\n',
+    'baz, hello\r',
+    '\n world.',
+    '\r\n Node.JS rules!!\r\n\r\n',
+  ];
+  for (const chunk of chunks)
+    ss.push(Buffer.from(chunk));
+
+  // output:
+  //
+  // data: 'foo'
+  // data: ' bar'
+  // match!
+  // data: 'baz, hello'
+  // match!
+  // data: ' world.'
+  // match!
+  // data: ' Node.JS rules!!'
+  // match!
+  // data: ''
+  // match!
+```
+
+
+API
+===
+
+Properties
+----------
+
+* **maxMatches** - < _integer_ > - The maximum number of matches. Defaults to `Infinity`.
+
+* **matches** - < _integer_ > - The current match count.
+
+
+Functions
+---------
+
+* **(constructor)**(< _mixed_ >needle, < _function_ >callback) - Creates and returns a new instance for searching for a _Buffer_ or _string_ `needle`. `callback` is called any time there is non-matching data and/or there is a needle match. `callback` will be called with the following arguments:
+
+  1. `isMatch` - _boolean_ - Indicates whether a match has been found
+
+  2. `data` - _mixed_ - If set, this contains data that did not match the needle.
+
+  3. `start` - _integer_ - The index in `data` where the non-matching data begins (inclusive).
+
+  4. `end` - _integer_ - The index in `data` where the non-matching data ends (exclusive).
+
+  5. `isSafeData` - _boolean_ - Indicates if it is safe to store a reference to `data` (e.g. as-is or via `data.slice()`) or not, as in some cases `data` may point to a Buffer whose contents change over time.
+
+* **destroy**() - _(void)_ - Emits any last remaining unmatched data that may still be buffered and then resets internal state.
+
+* **push**(< _Buffer_ >chunk) - _integer_ - Processes `chunk`, searching for a match. The return value is the last processed index in `chunk` + 1.
+
+* **reset**() - _(void)_ - Resets internal state. Useful for when you wish to start searching a new/different stream for example.
