# changes. For local development this should always
# be an empty file and therefore this layer should
# cache well.

# This layer is populated with up-to-date files from
# Calypso development.

# Build the final layer
#
# This contains built environments of Calypso. It will
# change any time any of the Calypso source-code changes.
