I've been writing a little project in Python, a Zandronum query tool.
https://gitlab.com/SkipGrube/zquery
The program queries a running server and displays info like players, score, ping, map, server version, etc.
Output is customizable using macros inside template files, but by default produces HTML. The idea is for server owners/operators to publish real-time player stats.
Might be useful for anyone hosting server(s).
Let me know what you think, or if there are any questions about it!
(EDIT: Shameless plug for my personal Zandronum server homepage, showing off the real-time stats from ZQuery: http://wolf3d.linuxdn.org
