# Assemble menubar-pet.app around the SwiftPM executable.
#
# SwiftPM cannot emit a .app, and a menu-bar app needs one: LSUIElement is what
# keeps it out of the Dock and off the window list. Rather than take on an
# .xcodeproj — which would stop `swift build` being the whole story and make
# the Homebrew formula harder — the bundle is four files and a script.
#
#   bundle.sh <built-executable> <output-dir>
#
# Writes <output-dir>/menubar-pet.app.
