Bug report

Style files (actually, style dicts) can be distributed as python packages, as discussed e.g. in #14943 (comment). This has the advantage of being relatively easy to do and that it works "as is" for essentially all versions of matplotlib (if your matplotlib is too old to have matplotlib.style.use (pre 1.5...) you can still use rcParams.update(style_dict)).

In today's call we agreed that this approach should be documented and that a template package (similar to https://github.com/matplotlib/matplotlib-cmap-template) could be created.

It was also pointed out during the call that this approach makes it easy to distribute colormaps together with the style, or add any additional custom logic; this may be worth documenting too.
