To build and publish a tag:

./release.sh <tag>

If the tag is new, you'll have to create a build/<tag>.sh file. Just copying the second-most-recent tag's build file will probably work.

To build and publish an arbitrary commit:

./release.sh <sha>

This will run the build file of the tag immediately preceding the commit, and will use the output of git describe --tags as the release name.

Of course, if you don't work at DataPad, you'll have to clone this repo to run these commands (the script will automatically use the right git endpoint). Pull requests containing new build files welcome.
