This is somewhat outdated, it seems. I've edited the links there to point to sources on github, but there is nothing about sage-tdlib in setup.py any more. There is sagemath-tdlib in src/sage/misc/package_dir.py, etc... probably it's best to be edited further not by me, but by someone who knows details. > > > On Wednesday, March 15, 2023 at 6:56:32 PM UTC-7 Brent W.
