+
+Node.js middleware for serving a favicon.
+
+Why use this module?
+
+  - User agents request `favicon.ico` frequently and indiscriminately, so you
+    may wish to exclude these requests from your logs by using this middleware
+    before your logger middleware.
+  - This module caches the icon in memory to improve performance by skipping
+    disk access.
+  - This module provides an `ETag` based on the contents of the icon, rather
+    than file system properties.
+  - This module will serve with the most compatible `Content-Type`.
+
+## Install
+
+```bash
+npm install serve-favicon
+```
+
+## API
+
+### favicon(path, options)
+
+Create new middleware to serve a favicon from the given `path` to a favicon file.
+`path` may also be a `Buffer` of the icon to serve.
+
+#### Options
+
+Serve favicon accepts these properties in the options object.
+
+##### maxAge
+
+The `cache-control` `max-age` directive in `ms`, defaulting to 1 day. This can
+also be a string accepted by the [ms](https://www.npmjs.org/package/ms#readme)
+module.
+
+## Examples
+
+Typically this middleware will come very early in your stack (maybe even first)
+to avoid processing any other middleware if we already know the request is for
+`/favicon.ico`.
+
+### express
+
+```javascript
+var express = require('express');
+var favicon = require('serve-favicon');
+
+var app = express();
+app.use(favicon(__dirname + '/public/favicon.ico'));
+
+// Add your routes here, etc.
+
+app.listen(3000);
+```
+
+### connect
+
+```javascript
+var connect = require('connect');
+var favicon = require('serve-favicon');
+
+var app = connect();
+app.use(favicon(__dirname + '/public/favicon.ico'));
+
+// Add your middleware here, etc.
+
+app.listen(3000);
+```
+
+### vanilla http server
+
+This middleware can be used anywhere, even outside express/connect. It takes
+`req`, `res`, and `callback`.
+
+```javascript
+var http = require('http');
+var favicon = require('serve-favicon');
+var finalhandler = require('finalhandler');
+
+var _favicon = favicon(__dirname + '/public/favicon.ico');
+
+var server = http.createServer(function onRequest(req, res) {
+  var done = finalhandler(req, res);
+
+  _favicon(req, res, function onNext(err) {
+    if (err) return done(err);
+
+    // continue to process the request here, etc.
+
+    res.statusCode = 404;
+    res.end('oops');
+  });
+});
+
+server.listen(3000);
+```

+Create simple ETags
+
+## Installation
+
+```sh
+$ npm install etag
+```
+
+## API
+
+```js
+var etag = require('etag')
+```
+
+### etag(entity, [options])
+
+Generate a strong ETag for the given entity. This should be the complete
+body of the entity. Strings, `Buffer`s, and `fs.Stats` are accepted. By
+default, a strong ETag is generated except for `fs.Stats`, which will
+generate a weak ETag (this can be overwritten by `options.weak`).
+
+```js
+res.setHeader('ETag', etag(body))
+```
+
+#### Options
+
+`etag` accepts these properties in the options object.
+
+##### weak
+
+Specifies if a "strong" or a "weak" ETag will be generated. The ETag can only
+really be a strong as the given input.
+
+## Testing
+
+```sh
+$ npm test
+```

+
+Module for calculating Cyclic Redundancy Check (CRC).
+
+## Features
+
+* Full test suite comparing values against reference `pycrc` implementation.
+* Version 3.x is 3x to 4x faster than version 2.x.
+* Pure JavaScript implementation, no dependencies.
+* Provides CRC Tables for optimized calculations.
+* Provides support for the following CRC algorithms:
+  * CRC1 `crc.crc1(…)`
+  * CRC8 `crc.crc8(…)`
+  * CRC8 1-Wire `crc.crc81wire(…)`
+  * CRC16 `crc.crc16(…)`
+  * CRC16 CCITT `crc.crc16ccitt(…)`
+  * CRC16 Modbus `crc.crc16modbus(…)`
+  * CRC24 `crc.crc24(…)`
+  * CRC32 `crc.crc32(…)`
+
+## IMPORTANT
+
+If you've used `crc` module prior to version 2.x, you might have some inconsistentcies with the current implementation because it relied on very old code and wasn't checked against reference implementation. If you upgrading from 1.x, please take special care.
+
+## Support
+
+<a href="https://blockchain.info/address/1CZyBREeHTmy8C5zVGHZHPwqBuWFmEuUCQ"><img src="bitcoin.png" width="150" align="right"/></a> Please support me on [GitTip](https://www.gittip.com/alexgorbatchev/). I've spend days developing and grooming this module and hope to spend more time. If you have bitcoin, please use the QR code or this wallet address [`1CZyBREeHTmy8C5zVGHZHPwqBuWFmEuUCQ`](https://blockchain.info/address/1CZyBREeHTmy8C5zVGHZHPwqBuWFmEuUCQ):
+
+## Installation
+
+    npm install crc
+
+## Running tests
+
+    $ npm install
+    $ npm test
+
+## Usage Example
+
+Calculate a CRC32:
+
+    var crc = require('crc');
+
+    crc.crc32('hello').toString(16);
+    # => "3610a686"
+
+Calculate a CRC32 of a file:
+
+    crc.crc32(fs.readFileSync('README.md', 'utf8')).toString(16);
+    # => "127ad531"
+
+Or using a `Buffer`:
+
+    crc.crc32(fs.readFileSync('README.md')).toString(16);
+    # => "127ad531"
+
+Incrementally calculate a CRC32:
+
+    value = crc32('one');
+    value = crc32('two', value);
+    value = crc32('three', value);
+    value.toString(16);
+    # => "09e1c092"
+

+HTTP response freshness testing
+
+## Installation
+
+```
+$ npm install fresh
+```
+
+## API
+
+```js
+var fresh = require('fresh')
+```
+
+### fresh(req, res)
+
+ Check freshness of `req` and `res` headers.
+
+ When the cache is "fresh" __true__ is returned,
+ otherwise __false__ is returned to indicate that
+ the cache is now stale.
+
+## Example
+
+```js
+var req = { 'if-none-match': 'tobi' };
+var res = { 'etag': 'luna' };
+fresh(req, res);
+// => false
+
+var req = { 'if-none-match': 'tobi' };
+var res = { 'etag': 'tobi' };
+fresh(req, res);
+// => true

+# parseurl
+
+[![NPM version](https://badge.fury.io/js/parseurl.svg)](http://badge.fury.io/js/parseurl)
+[![Build Status](https://travis-ci.org/expressjs/parseurl.svg?branch=master)](https://travis-ci.org/expressjs/parseurl)
+[![Coverage Status](https://img.shields.io/coveralls/expressjs/parseurl.svg?branch=master)](https://coveralls.io/r/expressjs/parseurl)
+
+Parse a URL with memoization.
+
+## Install
+
+```bash
+$ npm install parseurl
+```
+
+## API
+
+```js
+var parseurl = require('parseurl')
+```
+
+### parseurl(req)
+
+Parse the URL of the given request object (looks at the `req.url` property)
+and return the result. The result is the same as `url.parse` in Node.js core.
+Calling this function multiple times on the same `req` where `req.url` does
+not change will return a cached parsed object, rather than parsing again.
+
+### parseurl.original(req)
+
+Parse the original URL of the given request object and return the result.
+This works by trying to parse `req.originalUrl` if it is a string, otherwise
+parses `req.url`. The result is the same as `url.parse` in Node.js core.
+Calling this function multiple times on the same `req` where `req.originalUrl`
+does not change will return a cached parsed object, rather than parsing again.
+
