private branch!
- Code to be included should be branched of the upstream "master" branch
- Exception: Bugfixes to a version branch
- Code submissions should be in your master branch
- Other branches are fine as well, but you need to tell me which branch
your work is in!
- On a merge request, always name the branch I should pull from
- Always ensure **all** manpages build: ./build.sh man
- If you developed more than **one** feature, consider submitting them in
seperate branches. This way one feature can already be included, even if
the other needs to be improved.
