# 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..
