"""Packages prebuilts and SDK sources for GitHub releases.
Usage: ./tools/release/package-github-release-artifacts v20.0
IMPORTANT: This script must be run from the git tag being packaged. The SDK
source files are generated from the current working directory, so running this
script from a different commit will result in mismatched SDK sources.
This will generate:
- One .zip file for every os-arch combo (e.g. android-arm.zip)
- SDK source zips (perfetto-cpp-sdk-src.zip, perfetto-c-sdk-src.zip)
All files will be placed into /tmp/perfetto-v20.0-github-release/ .
