run_kotoed_watching_static.sh

#!/usr/bin/env bash

# This script runs Kotoed and webpack watching static in parallel.
#
# The whole purpose of this mess is to ensure that webpack dies before Kotoed
# Otherwise webpack may recreate .vertx/file-cache- directory,
# so we will have two file caches on next run and webpack.config.watch.ts
# won't be able to find Vertx file cache next time.
