Hi,
I'm reviewing your package !
1. it would be great to team-maintain this into nginx or lua team.
Please consider it ! (you'll need to request salsa access to the team
that fits you the best, move your repo there, and update d/control to reflect those changes).
2. Do not depend on nginx-extras. Nginx now builds all its modules in separate packages.
3. Depend on libnginx-mod-http-lua.
3. d/control long description contains a huge part that describes what is
libnginx-mod-http-lua, not this package. That's overkill.
Also it mentions nginx-extras too, which should be removed.
4. the d/watch file could be updated, see uscan(1) #github
