Like FS streams, but with stat on them, and supporting directories and symbolic links, as well as normal files. Also, you can use this to set the stats on a file, even if you don't change its contents, or to create a symlink, etc. So, for example, you can "write" a directory, and it'll call `mkdir`. You can specify a uid and gid, and it'll call `chown`. You can specify a `mtime` and `atime`, and it'll call `utimes`. You can call it a symlink and provide a `linkpath` and it'll call `symlink`. Note that it won't automatically resolve symbolic links. So, if you call `fstream.Reader('/some/symlink')` then you'll get an object that stats and then ends immediately (since it has no data). To follow symbolic links, do this: `fstream.Reader({path:'/some/symlink', follow: true })`. There are various checks to make sure that the bytes emitted are the same as the intended size, if the size is set. ## Examples ```javascript fstream .Writer({ path: "path/to/file" , mode: 0755 , size: 6 }) .write("hello\n") .end() ``` This will create the directories if they're missing, and then write `hello\n` into the file, chmod it to 0755, and assert that 6 bytes have been written when it's done. ```javascript fstream .Writer({ path: "path/to/file" , mode: 0755 , size: 6 , flags: "a" }) .write("hello\n") .end() ``` You can pass flags in, if you want to append to a file. ```javascript fstream .Writer({ path: "path/to/symlink" , linkpath: "./file" , SymbolicLink: true , mode: "0755" // octal strings supported }) .end() ``` If isSymbolicLink is a function, it'll be called, and if it returns true, then it'll treat it as a symlink. If it's not a function, then any truish value will make a symlink, or you can set `type: 'SymbolicLink'`, which does the same thing. Note that the linkpath is relative to the symbolic link location, not the parent dir or cwd. ```javascript fstream .Reader("path/to/dir") .pipe(fstream.Writer("path/to/other/dir")) ``` This will do like `cp -Rp path/to/dir path/to/other/dir`. If the other dir exists and isn't a directory, then it'll emit an error. It'll also set the uid, gid, mode, etc. to be identical. In this way, it's more like `rsync -a` than simply a copy.
