  # WHY:
  # This import will give you the following variables:
  # _sudo="sudo -E" <- only if non root user
  # distro = <distro name, like 'arch', 'debian', 'fedora'..>
  # arch = bool
  # fedora = bool
  # opensuse =  bool....
  # You can then use it for, `if $arch; then`
  # Also this gives you the _install command, which installs a package pased on the packagemanager/distro used.
  # CAUTION:
  # This only wokrs for generic package names, like neovim, or vim, or tmux etc..
  # not every package packagemanager has the same packagenames for their packages..
