# Vendors the matrix-rtc crate's uniffi web bindings into
# src/matrix-rtc-sdk/generated/. Until the crate ships as an npm package this
# is how Element Call picks up a new build of it: build it there, copy the
# generated TypeScript, the wasm-bindgen glue and the wasm here.

#   scripts/sync-matrix-rtc-sdk.sh [path-to-MatrixSdkArchitectureDraft] [--no-build]
#
# The build uses web-test-app/ubrn.element-call.config.yaml (feature `uniffi`
# only, release profile, its own output directory so the app's test build is
# left alone). Pass --no-build to copy whatever was built last.
