$tempdir = tempdir( $template, CLEANUP => 1);

           Create a temporary directory using the supplied template, but
           attempt to remove it (and all files inside it) when the program
           exits. Note that an attempt will be made to remove all files from
           the directory even if they were not created by this module (other-
           wise why ask to clean it up?). The directory removal is made with
           the rmtree() function from the File::Path module.  Of course, if
           the template is not specified, the temporary directory will be cre-
           ated in tmpdir() and will also be removed at program exit.
