# integrated, include the text "internal" somewhere in the tag name, such as
#
# 1.2.3.4.5-internal
# 1.2.3.4.5-internal-mkirk
#
# NOTE: that if you upload the build to test flight, you still need to give testflight
# a numeric build number - so tag won't match the build number exactly as they do
# with production build tags. That's fine.
#
# To avoid collision with "production" build numbers, use at least a 5
# digit build number.
