Repositories: Guideline for .gitattributes

[andreashaerter]

We often provide smaller tools and plugins where automatically release-tarballs are more then enough. When creating a release, Github creates a zip and a tar archive (the so called zipball and tarball), you can also get them via specific URLs:

https://api.github.com/repos/<user|org>/<repo>/tarball
https://api.github.com/repos/<user|org>/<repo>/zipball
https://api.github.com/repos/<user|org>/<repo>/tarball/<tag>
https://api.github.com/repos/<user|org>/<repo>/zipball/<tag>

However, these archives contain all files found in the projects repository. To exclude repository content (e.g. documentation, .git-files and so one) from being added to these archives, export-ignore can be used as the release feature pays attention to .gitattributes

Therefore, a useful template for .gitattributes would be as useful als it is for .gitignore
