# Use "gh api" to trigger rebuild in another GitHub repository
# (using GitHub Actions workflow repository_dispatch event).
# Useful to send after CGE Docker unstable image changes, to rebuild
# CGE demo/example projects using this Docker image.
#
# Params:
# $1 - SHA of this repo causing it. This may be useful for debug purposes later,
#      to track what commit caused the rebuild.
#      Pass ${{ github.sha }} from .github/workflows/after-build.yml
# $2 - GitHub repository name (e.g. "castle-engine/castle-model-viewer").
#
# See repository_dispatch docs:

# Needs GH CLI installed, and $GH_TOKEN set (with proper permissions, see above docs).
