Just a thought: it would be nice if the README file documented which version of Django's templates was supported, ie "templates as implemented in Django 1.3" or something.
It doesn't look like blocks within conditions are supported, nor autoescape by default. Both things that have changed in Django later than earlier, so it's good to know what version erlydtl supports and what version it aims to support in future.
This is a great idea. The only problem is that I have no idea what version of Django template language is actually supported (if any -- there are probably features in here spanning multiple versions).
Development at this point tends to be haphazard according to patches that I receive. If I had more time I'd love to make a release that sync'ed up with each major Django version, but that is not a possibility right now.
A useful contribution would be making a test suite that compared ErlyDTL output to different versions of Django and reported the number of filters and tags that were supported in each version. There is a start here but it was abandoned a long time ago:
Heh.. I was just thinking along the same lines.. will look into it, eventually.
