+
+> **trough** /trôf/ — a channel used to convey a liquid.
+
+`trough` is like [`ware`][ware] with less sugar, and middleware
+functions can change the input of the next.
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install trough
+```
+
+## Usage
+
+```js
+var fs = require('fs')
+var path = require('path')
+var trough = require('trough')
+
+var pipeline = trough()
+  .use(function(fileName) {
+    console.log('Checking... ' + fileName)
+  })
+  .use(function(fileName) {
+    return path.join(process.cwd(), fileName)
+  })
+  .use(function(filePath, next) {
+    fs.stat(filePath, function(err, stats) {
+      next(err, {filePath, stats})
+    })
+  })
+  .use(function(ctx, next) {
+    if (ctx.stats.isFile()) {
+      fs.readFile(ctx.filePath, next)
+    } else {
+      next(new Error('Expected file'))
+    }
+  })
+
+pipeline.run('readme.md', console.log)
+pipeline.run('node_modules', console.log)
+```
+
+Yields:
+
+```txt

+## API
+
+### `trough()`
+
+Create a new [`Trough`][trough].
+
+#### `trough.wrap(middleware, callback[, ...input])`
+
+Call `middleware` with all input.
+If `middleware` accepts more arguments than given in input, and extra `done`
+function is passed in after the input when calling it.
+It must be called.
+
+The first value in `input` is called the main input value.
+All other input values are called the rest input values.
+The values given to `callback` are the input values, merged with every
+non-nully output value.
+
+*   If `middleware` throws an error, returns a promise that is rejected, or
+    calls the given `done` function with an error, `callback` is invoked with
+    that error
+*   If `middleware` returns a value or returns a promise that is resolved, that
+    value is the main output value
+*   If `middleware` calls `done`, all non-nully values except for the first one
+    (the error) overwrite the output values
+
+### `Trough`
+
+A pipeline.
+
+#### `Trough#run([input..., ]done)`
+
+Run the pipeline (all [`use()`][use]d middleware).  Invokes [`done`][done]
+on completion with either an error or the output of the last middleware
+
+> Note! as the length of input defines whether [async][] functions get a `next`
+> function, it’s recommended to keep `input` at one value normally.
+
+##### `function done(err?, [output...])`
+
+The final handler passed to [`run()`][run], invoked with an error
+if a [middleware function][fn] rejected, passed, or threw one, or
+the output of the last middleware function.
+
+#### `Trough#use(fn)`
+
+Add `fn`, a [middleware function][fn], to the pipeline.
+
+##### `function fn([input..., ][next])`
+
+A middleware function invoked with the output of its predecessor.
+
+###### Synchronous
+
+If `fn` returns or throws an error, the pipeline fails and `done` is
+invoked with that error.
+
+If `fn` returns a value (neither `null` nor `undefined`), the first
+`input` of the next function is set to that value (all other `input`
+is passed through).
+
+The following example shows how returning an error stops the pipeline:
+
+```js
+var trough = require('trough')
+
+trough()
+  .use(function(val) {
+    return new Error('Got: ' + val)
+  })
+  .run('some value', console.log)
+```
+
+Yields:
+
+```txt
+Error: Got: some value
+    at ~/example.js:5:12
+    ...
+```
+
+The following example shows how throwing an error stops the pipeline:
+
+```js
+var trough = require('trough')
+
+trough()
+  .use(function(val) {
+    throw new Error('Got: ' + val)
+  })
+  .run('more value', console.log)
+```
+
+Yields:
+
+```txt
+Error: Got: more value
+    at ~/example.js:5:11
+    ...
+```
+
+The following example shows how the first output can be modified:
+
+```js
+var trough = require('trough')
+
+trough()
+  .use(function(val) {
+    return 'even ' + val
+  })
+  .run('more value', 'untouched', console.log)
+```
+
+Yields:
+
+```txt
+null 'even more value' 'untouched'
+```
+
+###### Promise
+
+If `fn` returns a promise, and that promise rejects, the pipeline fails
+and `done` is invoked with the rejected value.
+
+If `fn` returns a promise, and that promise resolves with a value
+(neither `null` nor `undefined`), the first `input` of the next function
+is set to that value (all other `input` is passed through).
+
+The following example shows how rejecting a promise stops the pipeline:
+
+```js
+var trough = require('trough')
+
+trough()
+  .use(function(val) {
+    return new Promise(function(resolve, reject) {
+      reject('Got: ' + val)
+    })
+  })
+  .run('val', console.log)
+```
+
+Yields:
+
+```txt
+Got: val
+```
+
+The following example shows how the input isn’t touched by resolving
+to `null`.
+
+```js
+var trough = require('trough')
+
+trough()
+  .use(function() {
+    return new Promise(function(resolve) {
+      setTimeout(function() {
+        resolve(null)
+      }, 100)
+    })
+  })
+  .run('Input', console.log)
+```
+
+Yields:
+
+```txt
+null 'Input'
+```
+
+###### Asynchronous
+
+If `fn` accepts one more argument than the given `input`, a `next`
+function is given (after the input).  `next` must be called, but doesn’t
+have to be called async.
+
+If `next` is given a value (neither `null` nor `undefined`) as its first
+argument, the pipeline fails and `done` is invoked with that value.
+
+If `next` is given no value (either `null` or `undefined`) as the first
+argument, all following non-nully values change the input of the following
+function, and all nully values default to the `input`.
+
+The following example shows how passing a first argument stops the
+pipeline:
+
+```js
+var trough = require('trough')
+
+trough()
+  .use(function(val, next) {
+    next(new Error('Got: ' + val))
+  })
+  .run('val', console.log)
+```
+
+Yields:
+
+```txt
+Error: Got: val
+    at ~/example.js:5:10
+```
+
+The following example shows how more values than the input are passed.
+
+```js
+var trough = require('trough')
+
+trough()
+  .use(function(val, next) {
+    setTimeout(function() {
+      next(null, null, 'values')
+    }, 100)
+  })
+  .run('some', console.log)
+```
+
+Yields:
+
+```txt
+null 'some' 'values'
+```
