"""
scripts/release/repo_release.py

Run after every `pyinstaller labui.spec` build, from anywhere (paths are
made absolute below before the working directory changes). Packages the
freshly built dist/LabUI bundle as a new signed tufup target.

Prerequisites:
  - repo_init.py has been run once already (./repository and ./keystore exist)
  - core/version.py has been bumped to the new version
  - dist/LabUI/ exists (pyinstaller labui.spec has just been run)

After this completes, see README.md in this directory for how to publish
the updated ./repository/metadata and ./repository/targets files to the
"updates" GitHub Release.
