# make-package.sh - build an OTA update package for ButtonTask.
#
# Produces dist/buttontask-<version>.tar.gz containing:
#   ButtonTask        (the compiled binary)
#   webconfig/        (the web configurator + scripts)
#   manifest.json     ({"version": ..., "created": ...})
# and prints the package's sha256 (paste it into the web UI for integrity).
#
# Usage:
#   make-package.sh <version> [build-dir] [out-dir]
# Example:
#   ./webconfig/scripts/make-package.sh 2.1 build dist
