Notes for astropy-helpers contributors ====================================== Note about versions ------------------- As described in `APE4 `_, the version numbers for astropy-helpers follow the corresponding major/minor version of the `astropy core package `_, but with an independent sequence of micro (bugfix) version numbers. Hence, the initial release is 0.4, in parallel with Astropy v0.4, which will be the first version of Astropy to use astropy-helpers. Trying out changes ------------------ If you contribute a change to astropy-helpers and want to try it out with a package that already uses astropy-helpers, install astropy-helpers from your branch of the repository in editable mode:: pip install -e . Then go to your package and add the ``--use-system-astropy-helpers`` for any ``setup.py`` command you want to check, e.g.:: python setup.py build_docs --use-system-astropy-helpers This will cause the installed version to be used instead of any local submodule.
