# Output a nice graph of why stuff isn't yet in Debian Testing.
#
# - Red oval nodes means it's not in Debian
# - Yellow oval nodes means it's in Debian, but something else needs a
#   different version of it.
# - For nodes with no children, it probably means that there is an older
#   version already in Debian Testing, and something else needs this specific
#   older version and can't work with the newer version. Unfortunately the
#   excuses page gives no more details about this, and you will have to ask
#   #debian-release to help you interpret https://release.debian.org/britney/update_output.txt
