# This script helps since version v0.8.30. Starting with this version
# a few feature has been introduced and is highly required to build
# 0.8.30 and above for Polkadot and Kusama.
# Lower version however, do not support this feature.
#
# This script checks the project version and return to stdout either:
# - nothing for version up to 0.8.30 excluded
# - --features on-chain-release-build for 0.8.30 and up for Kusama and Polkadot

# NOTE: We start using the new feature only if Cargo.toml contains version
# 0.8.30 or above. That means that commit after the feature was introduced
# and until Cargo.toml is updated will likely not work.
# srtool cannot count on the source to be a git repo.
