# Quickly builds an OpenMV IDE installer with a tiny fake payload (one file)
# so archivegen + binarycreator finish in seconds. The installer is assembled
# from the real dist/installer/ifw config + package meta, so every wizard page
# (intro, install folder, ready, finished, custom widgets) renders exactly as
# it does in a shipping build -- ideal for eyeballing layout/style/spacing
# without doing a full IDE compile.
#
# Usage:  python test_installer.py
# Output: build/openmv-ide-uitest-<version>(.exe) -- run it to inspect the UI.
