 As a Git repository the file isn't all that useful.  You can export it in other formats as follows:
 
 ```bash
-python makeJargon.py
+python2 makeJargon.py
 ```
 All of the resulting documents can be found in the _docs_ subdirectory.  Current formats supported are manpages, HTML and org-mode markup.
