Could you please run update_readme.sh and genmanpage.sh and include those changes? We used to have make docs but that is not yet ported to CMake.

update_readme.sh created a README.md which did not include the help output. Redirecting it may not work in MSYS2 (mintty)? Editing manually.

genmanpage.sh did not work at all in MSYS2, only created a stub with commands to be executed to fill this file, instead of their results:
