Create conda package across many versions

Question

I have a very simple Pure Python package on PyPI that I'd like to make available on binstar. My package targets Python 2.6+ and 3.2+ with a single codebase. I also expect that it works equally well on Windows as well as Unix.

Is there a simple way to comprehensively build my package and upload it to binstar for many Python versions?

I've tried a naive use of conda skeleton pypi as suggested in this article. I'd like to replicate this process across many different versions.

If you want to build recipes for many different versions of the package, use the --version flag to conda skeleton pypi. I recommend using package-version as a naming convention for the recipes.

If you want to build the same package for many different Python versions, use the --py flag to conda build, like conda build --py 3.4 recipe. The flag can be specified multiple times, like conda build --py 3.3 --py 3.4 recipe, or you can use --py all to build against Python 2.6, 2.7, 3.3, and 3.4.

To convert the package to other platforms, use conda convert (see conda convert -h for usage; be sure to run conda update conda-build, as the API changed a little bit recently).

The easiest way to get the binstar uploading is to run conda config --set binstar_upload yes. This will cause conda build and conda convert to upload the packages to binstar automatically when they are done.
