          Helpful iso info is no longer functional although still being offered:

(This is broken on HEAD of main btw, not by this PR so I'll push this comment to a new issue)

# master and web_pipe
 ./quickget 
ERROR! You must specify an operating system.
 - Operating Systems: alma [...]zorin

        You can also use these arguments:
        Only show ISO download URL
            --show-iso-url / -s {distro} {release} [edition]
        Test if ISO is available
            --test-iso-url / -t {distro} {release} [edition]
        Open distro homepage
            --open-distro-homepage / -o {distro}
        Only download ISO
            --download-iso / -d {distro} {release} [edition]

# 4.9.1 -ish

Sure is broken. Since I can't push all changes together, we will suffer till the new run script will be merged
