#!/usr/bin/env bash


# Here the quick 'n dirty guide to adding a new OS to quickget
#
#  1. Add the new OS, all lowercase, to os_support()
#  2. Add a "pretty name" display name to pretty_name()
#  3. Create a releases_newos() generator that outputs the currently supported release versions
#  4. Add the new OS to make_vm_config()
#  5. Create a get_newos() function that does something like this:
#     function get_newos() {
#         local HASH=""
#         local ISO=""
#         local URL=""
#
#         validate_release "releases_newos"
#         ISO="newos-${RELEASE}-amd64.iso"
#         URL="https://www.newos.org/download/${ISO}"
#         web_get "${URL}" "${VM_PATH}"
#         web_get "${URL}/SHA256SUMS" "${VM_PATH}"
#         HASH=$(cat "${VM_PATH}/SHA256SUMS" | cut -d' ' -f1)
#         check_hash "${ISO}" "${HASH}"
#         make_vm_config "${ISO}"
#     }
#  6. Add new OS to the argument parser at the bottom of the script
