# Automatically updates the App's build number
# This script should be executed by Xcode before every build

# It should mutate only the built version of the app to keep merges clean.
# (E.g. the Xcode project file just has a <scripted> placeholder string for the build number.)

# Pulls the major version FROM the Plist File (set in Xcode)
# Puts the generated build number INTO the Plist File (overwriting whatever was set in Xcode)
# Use LP specified format App_vX_YYMMDD.HHMM

# Build scripting strategy is described here:
