+{- | Returns the current directory for temporary files.
+
+On Unix, 'getTemporaryDirectory' returns the value of the @TMPDIR@
+environment variable or \"\/tmp\" if the variable isn\'t defined.
+On Windows, the function checks for the existence of environment variables in
+the following order and uses the first path found:
+
+* TMP environment variable.
+* TEMP environment variable.
+* USERPROFILE environment variable.
+* The Windows directory
+
+The operation may fail with:
+
+* 'UnsupportedOperation'
+The operating system has no notion of temporary directory.
+
+The function doesn\'t verify whether the path exists.
