Right, but the concept of environment markers is simple enough that we should be able to extend to other areas. Requirements are just the most obvious application. > That's great.

Which code do you mean? Although I have written some code to produce metadata in YAML format, I have not yet got anything that consumes it to a reasonable point (apart from sdist generation, which should not be environment-specific). I will publish what I have as soon as it has reached a reasonable state of usefulness. Precisely because it isn't declarative, existing environment-specific code in setup.py files in PyPI archives is not easy to convert to environment markers automatically :-( Regards, Vinay Sajip _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org http://mail.python.org/mailman/listinfo/distutils-sig
