// append a file from stream

archive.append(fs.createReadStream(file1), { name: 'AppleMusic' });*/

// append a file from string
/*archive.append('string cheese!', { name: 'file2.txt' });

// append a file from buffer
var buffer3 = new Buffer('buff it!');
archive.append(buffer3, { name: 'file3.txt' });

// append a file
archive.file('file1.txt', { name: 'file4.txt' });

// append files from a directory
archive.directory('subdir/');

// append files from a glob pattern
archive.glob('subdir/!*.txt');*/

// finalize the archive (ie we are done appending files but streams have to finish yet)
//archive.finalize();
