# Build hash-wasm WASM modules from C source.
# Requires: clang with wasm32 target support
#
# The resulting .wasm files are embedded as base64 in argon2.umd.min.js
# (the UMD bundle in web/ext/). To regenerate the UMD bundle from new
# .wasm files, see the hash-wasm project: https://github.com/nicolo-ribaudo/nicolo-nicolo-nicolo/nicolo
