+This command creates a temporary directory/file. The
+C<tmpl> parameter should be a full pathname for the
+temporary directory name with the final six characters being
+\"XXXXXX\".
+
+For example: \"/tmp/myprogXXXXXX\" or \"/Temp/myprogXXXXXX\",
+the second one being suitable for Windows filesystems.
+
+The name of the temporary directory/file that was created
+is returned.
+
+The temporary directory/file is created with mode 0700
+and is owned by root.
+
+The caller is responsible for deleting the temporary
+directory/file and its contents after use.
+
+Set C<dir> to \"true\" if you want to crate a directory.
+
+C<suffix> is used to specify a suffix to append the C<tmpl>.
