// scrape https://uupdump.net/known.php?q=feature+update+server+operating+system+20348+amd64
// NB there's a better way, using the API, e.g. https://api.uupdump.net/listid.php?search=feature+update+server+operating+system+20348+amd64
//    see https://github.com/uup-dump/json-api
// see https://github.com/uup-dump/website/blob/master/known.php
// see https://github.com/uup-dump/website/blob/master/get.php
// each scraped line is a tab separated string with 4 fields alike:
//    "Feature update to Microsoft server operating system, version 21H2 (20348.643) amd64\tx64\t2022-04-12 17:04:01 UTC\tb8e204fd-4e2b-4722-95d7-aad633ad7379"

                .split("\n")
                .map(l => l.split("\t"))

// then you can use the builds to create the download package at, e.g., to
// get the download package that gets the serverstandard edition:
//    https://uupdump.net/get.php?id=b8e204fd-4e2b-4722-95d7-aad633ad7379&pack=en-us&edition=serverstandard
// NB edition is a semicolon separated list, at most it can be:
//      serverdatacenter;serverdatacentercore;serverstandard;serverstandardcore
