I'm not sure what context files are you talking about. Can you explain? It would be nice to give a link on the source of your informtion.
Also, reading the docs and examples of the package is sometimes more helpful than going through the web

it is just a text file containing the sentence start and sentence end tags. A file with the following two lines work great for me.
