# Build Murmur.app (py2app alias mode) and sign it with a stable identity so
# macOS Accessibility permission persists across rebuilds.
#
# Usage:
#   ./build_app.sh
#
# Requires: py2app in the venv (pip install py2app) and a code-signing identity
# named "Murmur Code Signing" in your login keychain. See README (Building) for
# how to create the self-signed certificate the first time.
