# Produces dist/stoke_<version>_all.deb from a clean staging copy of the
# working tree (only src/, package.json and package-lock.json are shipped;
# production dependencies are installed fresh with `npm ci --omit=dev`).
#
# Requirements: bash, node/npm, dpkg-deb, gzip. Runs lintian when available.
