+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.

+# graceful-fs
+
+graceful-fs functions as a drop-in replacement for the fs module,
+making various improvements.
+
+The improvements are meant to normalize behavior across different
+platforms and environments, and to make filesystem access more
+resilient to errors.
+
+## Improvements over [fs module](http://api.nodejs.org/fs.html)
+
+graceful-fs:
+
+* Queues up `open` and `readdir` calls, and retries them once
+  something closes if there is an EMFILE error from too many file
+  descriptors.
+* fixes `lchmod` for Node versions prior to 0.6.2.
+* implements `fs.lutimes` if possible. Otherwise it becomes a noop.
+* ignores `EINVAL` and `EPERM` errors in `chown`, `fchown` or
+  `lchown` if the user isn't root.
+* makes `lchmod` and `lchown` become noops, if not available.
+* retries reading a file if `read` results in EAGAIN error.
+
+On Windows, it retries renaming a file for up to one second if `EACCESS`
+or `EPERM` error occurs, likely because antivirus software has locked
+the directory.
+
+## USAGE
+
+```javascript
+// use just like fs
+var fs = require('graceful-fs')
+
+// now go and do stuff with it...
+fs.readFileSync('some-file-or-whatever')
+```
