"""
scripts/release/repo_release.py

Run after every `pyinstaller labui.spec` build, on the same platform that
build was produced on (no cross-compiling — this packages whatever
dist/LabUI/ currently contains, which is only correct for the OS the build
just ran on). Packages the freshly built dist/LabUI bundle as a new signed
tufup target, in that platform's own repo tree.

Prerequisites:
  - repo_init.py has been run once already for this platform
    (./<platform>/repository and ./<platform>/keystore exist)
  - core/version.py has been bumped to the new version
  - dist/LabUI/ exists (pyinstaller labui.spec has just been run, on this
    same machine/OS)

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