See page 151 of the specs. There is a bunch of reserved property names. Populating them is optional (and not always meaningful), but for our caching problem, systematically filling javax.script.filename with the template filename looks appropriate. We don't want to use the getTemplate() method, since we are already given a String or a Reader towards the template. But since we also know the filename it comes from, we can cache and reuse the parsed template each time we get the same filename. GSOC officials say <<Monday, 13 August is our soft "pencils down" date. We suggest that students have completed their projects by this date and spend a week writing documentation and wrapping up their projects. We require that students stop all coding on 20 August.>> It's one week from now. I think that trying to achieve this last feature (Velocity resource caching based only on the filename) is a reachable goal.
