# Set Hokusai version in:
#
# - hokusai/VERSION file
#     'hokusai version' command retrieves version from this file.
#
# - pyproject.toml file tool.poetry.version field
#     This field decides the version number in artifact file names, and in PyPI.
#
# Set version differently depending on environment and Git branch.
#
# For 'release' branch build in CircleCI, set version to what is in hokusai/RELEASE_VERSION file.
#
# For all others, set it to:
#   - hokusai/RELEASE_VERSION, plus
#   - git rev-parse --short HEAD
# For example, if RELEASE_VERSION is 2.0.0 and git rev-parse is 680c2ad, set version to 2.0.0+680c2ad
# This is useful for identifying Beta builds.
