fn main() {
// Initialize a filesystem object
let img_file = std::fs::OpenOptions::new().read(true).write(true)
.open("fat.img").unwrap();
let buf_stream = fscommon::BufStream::new(img_file);
let fs = FileSystem::new(buf_stream, FsOptions::new()).unwrap();
let root_dir = fs.root_dir();
// Write a file
root_dir.create_dir("foo").unwrap();
let mut file = root_dir.create_file("foo/hello.txt").unwrap();
file.truncate().unwrap();
file.write_all(b"Hello World!").unwrap();

for r in dir.iter() {
let entry = r.unwrap();
println!("{}", entry.file_name());
