 If your contribution does not exceed the contribution limit (currently 1000 LOC) this will allow us to directly accept a pull request. If your contribution was not developed from scratch or contains content from other authors, please indicate this on the related Github Issue entry. As in cases where the contribution exceeds the limit, we will have to open a contribution questionnaire (and may have to ask for additional information via the related Github Issue entry) to handle such cases in compliance to the [Eclipse Legal Process](http://eclipse.org/legal/EclipseLegalProcessPoster.pdf).
