Generate .wfn file from an energy or optimization calculation

Dear all

I am a new and beginner psi4 user and I wonder if someone would answer my question.
How can I generate .wfn or molden output from a “single point energy” or an optimization calculation? what keyword should I use in the input file or maybe in the command line?

multiwfn is not currently supported, but maybe someday.

For molden support, please read the documentation.
