+# end-of-stream
+
+A node module that calls a callback when a readable/writable/duplex stream has completed or failed.
+
+	npm install end-of-stream
+
+## Usage
+
+Simply pass a stream and a callback to the `eos`.
+Both legacy streams and streams2 are supported.
+
+``` js
+var eos = require('end-of-stream');
+
+eos(readableStream, function(err) {
+	if (err) return console.log('stream had an error or closed early');
+	console.log('stream has ended');
+});
+
+eos(writableStream, function(err) {
+	if (err) return console.log('stream had an error or closed early');
+	console.log('stream has finished');
+});
+
+eos(duplexStream, function(err) {
+	if (err) return console.log('stream had an error or closed early');
+	console.log('stream has ended and finished');
+});
+
+eos(duplexStream, {readable:false}, function(err) {
+	if (err) return console.log('stream had an error or closed early');
+	console.log('stream has ended but might still be writable');
+});
+
+eos(duplexStream, {writable:false}, function(err) {
+	if (err) return console.log('stream had an error or closed early');
+	console.log('stream has ended but might still be readable');
+});
+
+eos(readableStream, {error:false}, function(err) {
+	// do not treat emit('error', err) as a end-of-stream
+});
+```
