+unbzip2-stream
+===
+streaming bzip2 decompressor in pure JS for Node and browserify.
+
+Buffers
+---
+When browserified, the stream emits instances of [feross/buffer](https://github.com/feross/buffer) instead of raw Uint8Arrays to have a consistant API across browsers and Node.
+
+Usage
+---
+``` js
+var bz2 = require('unbzip2-stream');
+var fs = require('fs');
+
+// decompress test.bz2 and output the result
+fs.createReadStream('./test.bz2').pipe(bz2()).pipe(process.stdout);
+```
+
+Also see [test/browser/download.js](https://github.com/regular/unbzip2-stream/blob/master/test/browser/download.js) for an example of decompressing a file while downloading.
+
+Or, using a &lt;script&gt; tag
+---
+
+```
+<script src="https://npm-cdn.info/unbzip2-stream/dist/unbzip2-stream.min.js"></script>
+<script>
+    var myStream = window.unbzip2Stream();
+    // now pipe stuff through it (see above)
+</script>
+```
+
+Tests
+---
+To run tests in Node:
+
+    npm run test
+
+To run tests in PhantomJS
+
+    npm run browser-test
+
+Additional Tests
+----------------
+There are two more tests that specifically test decompression of a very large file. Because I don't want to include large binary files in this repository, the files are created by running an npm script.
+
+    npm run prepare-long-test
+
+You can now
+
+    npm run long-test
+
+And to run a test in chrome that downloads and decompresses a large binary file
+
+    npm run download-test
+
+Open the browser's console to see the output.
