# Script to update the EMULATOR_BUILD version in a patch file based on the

#   - Reads the repository URL and commit hash from a configuration file
#   - Clones the repository
#   - Determines the latest tag leading up to the specified commit
#   - Updates the patch file with the new version
#
# Run this script and commit the result when new versions are tagged upstream.
