+# memory-fs
+
+A simple in-memory filesystem. Holds data in a javascript object.
+
+``` javascript
+var MemoryFileSystem = require("memory-fs");
+var fs = new MemoryFileSystem(); // Optionally pass a javascript object
+
+fs.mkdirpSync("/a/test/dir");
+fs.writeFileSync("/a/test/dir/file.txt", "Hello World");
+fs.readFileSync("/a/test/dir/file.txt"); // returns Buffer("Hello World")
+
+// Async variants too
+fs.unlink("/a/test/dir/file.txt", function(err) {
+	// ...
+});
+
+fs.readdirSync("/a/test"); // returns ["dir"]
+fs.statSync("/a/test/dir").isDirectory(); // returns true
+fs.rmdirSync("/a/test/dir");
+
+fs.mkdirpSync("C:\\use\\windows\\style\\paths");
+```
