# Sideload an Office add-in manifest for local debugging on macOS.
#
# Copies the manifest into each app's Documents/wef folder named
# <addin-id>.manifest.xml, so it (a) loads in Excel/Word/PowerPoint and
# (b) is later removable by ID with clear-addin-cache.sh.
#
# This does direct file copies — it does NOT use office-addin-dev-settings.
#
# Sideloading is additive and idempotent — it installs directly (no
# dry-run). Reverse it any time with clear-addin-cache.sh --id <GUID> --apply.
#
# Usage:
#   sideload-addin.sh /path/to/manifest.xml
