Bringing mapnik-reference up-to-date #159
Description
mapnik-reference is significantly behind mapnik, which is a growing problem for projects such as carto (now in a new organisation) and the OSM Carto map style.
Although not a complete solution for updating documentation, an up-to-date mapnik-reference would greatly improve the state of documentation.
Can we see a manageable route to restoring life to this project?
A lot of changes in 3.1 have been collated (#143), and it shouldn't be too difficult to draft documentation from the PRs without much expert knowledge. Documenting 3.1 would address most current mapnik installations (current Ubuntu and Debian distributions package 3.1).
Upcoming releases will be targetting newer versions: Ubuntu LTS Resolute (4.2) and Debian Trixie (4.0.7). [OSMF now run their OSM Carto servers on Debian.]
