# Here the quick 'n dirty guide to adding a new OS to quickget
#
#  1. Update os_support() - add new OS, all lowercase
#  2. Update pretty_name() - add a pretty name for new OS *only if the catch all is not suitable*
#  3. Create a releases_newos() generator (required) outputs the current supported release versions
#  4. Create a editions_newos() generator (optional) outputs the editions if new OS has multiple flavours/editions
#  5. Update make_vm_config() - add any *required* new OS tweaks
#  6. Create a get_newos() function - that does something like this:
#     function get_newos() {
#         local EDITION="${1:-}"
#         local HASH=""
#         local ISO="newos-${RELEASE}-${EDITION}-amd64.iso"
#         local URL="https://www.newos.org/download/${RELEASE}/${EDITION}"
#
#         HASH=$(wget -q -O- "${URL}/SHA512SUMS" | grep "${ISO}" | cut -d' ' -f1)
#         echo "${URL}/${ISO} ${HASH}"
#     }
