+//@ ### tempdir()
+//@
+//@ Examples:
+//@
+//@ ```javascript
+//@ var tmp = tempdir(); // "/tmp" for most *nix platforms
+//@ ```
+//@
+//@ Searches and returns string containing a writeable, platform-dependent temporary directory.
+//@ Follows Python's [tempfile algorithm](http://docs.python.org/library/tempfile.html#tempfile.tempdir).
