  # arch = bool
  # fedora = bool
  # opensuse =  bool....
  # You can then use it for, `if $arch; then`
  # Also this gives you the pkg-install command, which installs a package pased on the packagemanager/distro used.

  # 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..
