I'm a big fan of building a github repository directly, but is there a mechanism by which means we can exclude files from the build (similar to git's .gitignore, or heroku's .slugignore)? For instance, there's no need to include the specs or auxiliary files of use only to the developers in the final build, while they must obviously be kept as part of the repository. If no such mechanism exists, might I suggest that it be added?
