I built all of llvm using the Build Clang on Unix-like System instructions.

• That does not seem to include any man files for clang and the various tools. Something that is available through the dnf package manager via the llvm-doc RPM.
• The available package is for an older release (17.0.6-2 at this point). I want to use the latest and that’s why I built llvm/clang from source.

I searched for instructions or make rules for creating documentation, man files, but I did not see anything.

Question: How does one build the clang/llvm documentation from source?
