+io.mkdir("path", "mode"): Similar to mkdir(2). The mode is passed as a string
+  to allow for octal representations. This returns a success code (non 0 in
+  case of failure), and a more specific error code as its 2nd returned value
+  in case of failure. The error code is to be used with vlc.errno
+io.readdir("path"): Lists all files & directories in the provided folder.
+io.open("path"[, "mode"]): Similar to lua's io.open. Mode is optional and 
+  defaults to "r". It returns a file object with the following member functions:
+    .read
+    .write
+    .seek
+    .flush
+    .close
+  all of which are used exactly like the lua object returned by io.open
