obvious

ok I see output_dest was actually used but IMHO this should be something we use the shell for, i.e. output to stdout and redirect, using tee if neccessary

style bits (underscores between compound words, use dest always in optparse)

ans-command

Is there something we can use to generate manpages from markdown?

Also sort keys in JSON file and pretty print
