## 1. learn latest version file

latest_version="$( echo "${url_contents}" | grep -A1 'class="releaseRow"' | grep -E '<span>[0-9\.]+</span>' | sed -r -e 's/\s*<\/?span>\s*//g;' )"
### add domain as needed to filename
if ! echo "${latest_file}" | grep -q "^(ht|f)tps?:\/\/" ;
then
   latest_file="${domain}/${latest_file}"
fi

## 2. dl it
# WORKHERE
get "${latest_file}"
