 ### Ancient systems and versions of perl
 The code will not work with perl 5.8 or below (pre-modern perl). We no longer test against 5.10 (released 2007) or 5.12 (released 2010). If you're running a very old verison of Linux, you're also in trouble.
 
+### Running the tests

+
+```
+dzil test
+```
