### Examples ###

#### Streaming Uploads (from file) ####

```
// you must run fs.stat to get the file size for the content-length header (s3 requires this)
fs.stat(__filename, function(err, file_info) {
    var bodyStream = fs.createReadStream( __filename );

    var options = {
        BucketName    : bucket,
        ObjectName    : 'amazon.js',
        ContentLength : file_info.size,
        Body          : bodyStream
    };

    s3.PutObject(options, function(err, data) {
        fmt.dump(err, 'err');
        fmt.dump(data, 'data');
    });
});
