# We need the following:
# - fcgiwrap, because that is how nginx does CGI
# ----- IMPORTANT NOTE: This is custom build fcgiwrap package to account for NO_BUFFERING option.
# ----- Original fcgiwrap: https://github.com/gnosek/fcgiwrap
# ----- Custom fcgiwrap: https://github.com/notr1ch/fcgiwrap
# - git and git-daemon, because that gets us the git-http-backend CGI script
# - ruby, to run smartcloud gem
# - spawn-fcgi, to launch fcgiwrap and to create the unix socket
