options:

         Note that sub-packages must explicitly be enumerated in this
         list. Excluding foo.bar will not automatically exclude
         foo.bar.baz.

         A list of jar files and directories to include in the classpath
         (separated by spaces). This will be globbed for you, so you can
         pass in --cpath="lib/*.jar".
