The idea of having Fortran manpages sounds similar to what other language have available as reference/documentation:
- C++: https://en.cppreference.com/w/ (community supported documentation)
- Python: https://docs.python.org/3/ (supported by the Python software foundation)
- Julia: https://docs.julialang.org/en/v1/
While I don’t use man pages that often from the terminal, having an online searchable Fortran documentation website would be great. Right now the gfortran/Intel/IBM compiler documentation is the closest thing.
